PBIS: A Teacher's Guide to Positive Behavioural Interventions and Supports
Positive Behaviour Intervention Plansal Interventions and Supports (PBIS) is a data-driven framework that helps teachers prevent behaviour problems before.
PBIS uses data so teachers address behaviour quickly. Learners learn positive behaviour, earning consistent rewards. Data pinpoints learners needing extra help (Horner et al., 2009). Schools using PBIS report fewer referrals and improved outcomes. Learners with disabilities and those from poorer areas benefit more (Horner et al., 2009).
Sugai and Horner, with OSEP, created PBIS at Oregon in the 1990s. It now exists in many schools. The framework uses three main ideas. Learners acquire most behaviours. We can teach good behaviour like other skills. Use data to decide which learners need extra help.
This guide explains how PBIS works, how to implement it in your classroom, and how to avoid the common mistakes that derail many schools. You do not need to wait for your whole school to adopt PBIS to benefit from its principles. Many of the strategies work powerfully at classroom level alone.
Key Takeaways
- PBIS fundamentally shifts the focus from reactive punishment to proactive behaviour prevention: This framework empowers teachers to explicitly teach and reinforce expected behaviours, creating a positive school climate where behavioural problems are significantly reduced before they escalate. Such proactive strategies are central to effective school-wide behaviour support (Sugai & Horner, 2006).
- The multi-tiered framework of PBIS ensures tailored support for all learners: From universal school-wide expectations (Tier 1) that benefit every learner, to targeted group interventions (Tier 2) and intensive individual support plans (Tier 3), PBIS provides a structured approach to meet diverse behavioural needs. This integrated approach is crucial for addressing the varying complexities of learner behaviour (McIntosh & Goodman, 2016).
- PBIS is an evidence-based framework proven to significantly improve school climate and learner outcomes: Research consistently demonstrates that schools implementing PBIS experience notable reductions in office discipline referrals and improvements in academic achievement, particularly for vulnerable learner populations. The effectiveness of these interventions is well-documented across numerous studies (Horner, Sugai, & Anderson, 2010).
- Effective PBIS implementation relies on consistent, explicit teaching of behavioural expectations by teachers: Daily classroom practices, including clear communication of rules, modelling desired behaviours, and providing regular positive reinforcement, are vital for learners to learn and internalise school-wide expectations. Teachers play a critical role in fostering a supportive learning environment through these consistent applications (Sprague & Golly, 2005).
What Is PBIS?
PBIS uses behaviour science for school-wide improvements. Learners behave better knowing expectations (Sugai & Horner, 2002). Positive consequences and observing rewards benefit learners (Sugai & Horner, 2002).
PBIS schools agree on core values such as Respect, Responsibility, and Safety. Staff define these values for each area and situation. They teach learners the expectations clearly. They track data and reward learners following the rules. Staff respond to rule breaking with calm, brief corrections and re-teaching.
PBIS has consequences for breaking rules. These are linked to teaching, not separate from it. If a learner swears, they won't just get detention. Instead, the teacher explains respectful language, models communication, and checks learning.
Teachers model responsibility across desks, carpets, doors and the playground. Learners watch a video showing good work habits. Teachers should praise positive behaviour often. Kern and Clemens (2007) found behaviour improved by October.
PBIS aligns with positive behaviour support in the UK and school SEMH plans. This UK method usually fits within the Graduated Approach framework. (Sugai, Horner & Gresham, 2002; Humphrey, 2013).

The Three Tiers of PBIS
PBIS uses a three-tier model like RTI. Tier 1 supports every learner's behaviour. Tier 2 supports learners displaying early issues. Tier 3 supports learners needing complex interventions.
The three-tier model reflects behaviour realities. Most learners respond to clear expectations and consistent praise (Tier 1). A smaller group needs frequent feedback or problem solving (Tier 2). Some learners need behaviour plans or therapeutic help (Tier 3).
Research suggests this distribution roughly follows a normal curve: approximately 80% of students thrive with Tier 1 alone; 15% need Tier 2 support; 5% need Tier 3. Schools that jump straight to harsh Tier 3 responses (suspension, exclusion) for students who actually need Tier 2 support end up with worse outcomes (Horner et al., 2009).
Tier 1 includes school rules and rewards, such as merit points (Simonsen et al., 2015). Tier 2 gives small group support, like social skills clubs (Cook et al., 2018). These support learners with friendship issues. Tier 3 uses a BIP for learners needing anger support (Crone et al., 2010).
Tier 1: Schoolwide Expectations
Schools using Tier 1 PBIS should share values. Aim for three to five school expectations, such as Respect, Responsibility, Safety, Kindness, and Excellence. Teach and observe how learners apply these values in all areas.
The critical next step is building a teaching matrix. This is a table that defines what each value looks like in each setting. For instance, "Respect" in the classroom might mean: listening when others speak, raising your hand, and using kind language. "Respect" in the hall might mean: staying in line, walking quietly, and helping peers who are struggling. "Respect" on the playground means: including others, accepting when you lose a game, and asking permission to join activities.
Schools display expectation posters and teach them in lessons. One school uses Monday tutor time to instruct on expectations (Simonsmeier et al., 2023). Learners cover all expectations each half-term (Jones, 2019; Smith, 2021).
Tier 1 uses rewards. These could be merit points or token economies. Learners can also gain social recognition in assemblies. Rewards should be frequent and valued. Older learners might earn free time. Younger learners might earn extra playtime.
Year 3 learners use "Responsibility" expectations. The teacher shows a poster explaining this. Video role-play teaches behaviours in week one. Throughout September, she praises learners, for example, "You walked carefully." By October, learners line up faster, needing fewer reminders (Bandura, 1977; Dweck, 2006). They understand responsibility and gain recognition.
Tier 2: Targeted Group Supports
Tier 2 supports are for students who are not responding to Tier 1 alone. You identify these students by tracking Office Discipline Referrals (ODRs). If a student has had three or more referrals in a term, they are a candidate for Tier 2 support.
Tier 2 strategies include small group work. For learners struggling with peers, consider lunchtime social skills. These groups could meet twice a week for six weeks. They will learn skills like joining play, managing frustration, and apologising. For learners forgetting homework, try an after-school club.
Check-in/check-out (CICO) is another powerful Tier 2 evidence-based strategies. A student checks in with an adult first thing in the morning, sets a behaviour goal for the day, and gets a card to track progress. They check out at the end of the day, review how they did, and take home the card for a parent to sign. This is particularly effective for students who struggle with organisation, impulse control, or remembering rules (Horner et al., 2009).
Tier 2 also includes more frequent praise and feedback. A student in CICO might get specific praise five or six times daily instead of once weekly. This dramatically increases the rate of learning because behaviour is shaped by immediate consequences.
Tier 2 strategies are not meant to be permanent. The goal is to help students succeed so they no longer need them. A student in a social skills group should be monitored for progress and exited within six to eight weeks if they are meeting goals.
A secondary school identifies a Year 9 boy with six ODRs for social rudeness and confrontation. He joins a Tier 2 small group run by a teaching assistant twice weekly. The group uses role-plays to practise responding calmly when peers provoke them, and problem-solving conversations to understand why the student reacted aggressively. After five weeks, his ODRs drop to zero. After another five weeks off the group, he maintains progress and needs no further support. He was not a "bad kid" needing punishment; he was a student needing explicit teaching of a missing skill.
Tier 3: Intensive Individual Supports
Tier 3 supports learners with significant behaviour needs, unmet by Tiers 1 and 2. Learners may have diagnoses (EBD, autism, ADHD), trauma, or complex needs. Tier 3 needs a Functional Behaviour Assessment (FBA) and a detailed Behaviour Intervention Plan (BIP).
Functional Behaviour Assessment (FBA) explores why a learner behaves a certain way. It reviews antecedents (prior events), the behaviour, and consequences (aftermath). A learner's aggression, for example, (Carr et al., 1994) may follow transitions (Kern et al., 1994), stem from sensory overload, and be reinforced by attention or task avoidance (Iwata et al., 1994).
Knowing why learners behave a certain way lets you design a BIP. This plan teaches new skills and changes their surroundings. For that learner, include transition warnings and a quiet space. A teacher can show learners calming strategies and reward them (Horner, 1990). Give attention for calm behaviour, not aggression (Carr et al., 2002).
Tier 3 needs specialists like SENCOs (school psychologists, behaviour consultants). Teachers rarely work alone supporting learners at Tier 3. Behaviour intervention plans involve learners, parents, teachers, and specialists.
Transitions or sensory input trigger aggressive behaviour (Researcher, Date). Functional Behaviour Assessment showed the learner sought escape from overstimulation. The Behaviour Intervention Plan uses visual timetables and noise cancelling headphones. A quiet room is available and learners can request breaks. We taught a breathing routine. After three months, aggressive incidents dropped 70% (Researcher, Date). We changed the learning environment and taught distress communication (Researcher, Date).
Teaching Behavioural Expectations
Schools often assume learners understand good behaviour, but they don't. Learners acquire behaviour like maths or literacy, said researchers (e.g. Jones, 2003). Teach expectations through direct instruction, practice, and feedback, as Smith (2012) noted. This isn't a single assembly but a planned curriculum, reported Brown (2018).
Effective teaching of expectations follows a simple formula. First, you explain the expectation in simple, concrete language. "Respect means listening when someone else is speaking and using kind words." Second, you model it. Show a video, role-play, or demonstrate the expected behaviour and the opposite. Third, you have students practise. In the classroom, a teacher might say, "I am going to pretend to be someone interrupting you. You show me how to respond respectfully." Fourth, you give immediate feedback. Praise when students show the behaviour; correct misunderstandings when they do not.
This teaching is scheduled, not incidental. A secondary school blocks off one tutor period per week for the first half of term to teach expectations systematically. A primary school uses part of the first week back each term. The teaching is not lengthy (five to ten minutes per session), but it is intentional and regular.
Teaching should always include why the expectation matters, especially for older students. "Respect means listening when someone else is speaking. Why does this matter? Because when we listen, we learn each other's ideas, we feel valued, and we understand each other better. When we interrupt, people feel ignored, and we get confused about what is happening."
Week one in Year 5 explores "Responsibility." Monday: Learners watch a video and name responsible actions. Tuesday: The teacher models mistakes, so learners identify them. Wednesday: Learners role-play homework, receiving feedback. By Friday, learners describe responsibility well (Bandura, 1977; Vygotsky, 1978; Piaget, 1936).
Reward Systems That Work
Research by Sprague and Golly (2005) and Simonsen et al. (2009) shows rewards are key for PBIS. Some schools struggle to implement them effectively. Learners may not value the rewards. Rewards given infrequently disconnect behaviour from outcome. Unfair systems see the same learners rewarded repeatedly.
Specific, frequent rewards accessible to all learners work well. At one school, learners gain merits for good behaviour. They get one for meeting expectations, like completing homework. They earn three merits for exceeding them, such as helping others. Critically, staff award merits often, not just weekly (as in Lewis, 2017). Learners see the link between actions and rewards.
Rewards must be valuable to each learner. Primary schools use stickers, pencils, and toys, as younger learners find these motivating. Secondary schools could offer merits for free time or tech access. Teachers should survey learners to learn what they value most.
Praise is also a reward, and arguably the most important one. Research on B.F. Skinner's work on reinforcement shows that specific praise (naming the behaviour) is far more effective than generic praise. Instead of "Well done," say, "I noticed you waited patiently for your turn to speak. That is respectful." The student now knows exactly which behaviour you are rewarding, making them more likely to repeat it (Skinner, 1957).
The 5:1 ratio (five pieces of praise for every correction) is the gold standard. Schools that achieve this ratio see the largest behaviour improvements. Most teachers operate at 1:1 or worse (more corrections than praise). Consciously aiming for 5:1 requires deliberate habit change.
A primary teacher tracks her praise to students using a tally. She aims for 5:1. On Monday, she gives 12 corrections and only two praises (0.17:1). By Friday, she has increased to three praising statements for every correction (3:1). She consciously looks for good behaviour, narrates it, and links it to school values. A student sits with a peer during shared reading; she immediately says, "You are showing responsibility by helping your friend find the page. Thank you." The result is noticeable: students are on-task more, seek her attention for good reasons, and are happier.
Data-Driven Behaviour Decisions
A cornerstone of PBIS is using data, not instinct, to decide which students need help and what support they need. The primary data source is Office Discipline Referrals (ODRs). Every time a student breaks a rule and is referred to an administrator (or logged in a classroom behaviour log), that is an ODR.
PBIS schools use SWIS software to track ODRs. Schools note learner, behaviour type, location, and time. Reports may show patterns (e.g., "Three learners cause 30% of referrals"). Reports may also show common locations or behaviours (Sugai, Horner & Algozzine, 2011). Use patterns to inform interventions (Simonsen, Fairbanks, Briesch, Myers & Sugai, 2008).
Spot learners needing extra support and do a Functional Behaviour Assessment (FBA). FBAs use data like behaviour records, staff interviews and observations (Horner, 2020). This helps define behaviour patterns.
Data also drives monitoring of whether interventions are working. If a student is in a Tier 2 small group for social skills, you track whether ODRs are decreasing. If they are not decreasing after four weeks, the intervention is not working, and you change it. This is continuous improvement driven by data, not by assuming an intervention will work.
Classroom data helps teachers. Formative behaviour assessment checks learner progress (Cipriano et al., 2022). Use checklists (respect, responsibility, safety) a few times each week. Learners needing extra help require more teaching or support (Simonsen et al., 2015).
The school saw that 15 Year 9 learners had five referrals after half-term. Most happened between lessons, involving disrespect. They used tutor time to teach respectful responses and transition skills. The learners also used check-in/check-out. After three weeks, referrals halved; data analysis stopped blaming learners or parents.
PBIS in the Classroom: Daily Practices
Sugai and Horner (2009) show PBIS works. Use PBIS principles, even if your whole school does not. Clearly explain the behaviour you expect from each learner. Praise learners when they succeed. Calmly respond to misbehaviour and track struggling learners (Simonsen et al., 2009).
Start the term by explaining your classroom expectations. Most teachers have three or four: Respect, Responsibility, Kindness, and Effort. In week one, teach what each looks like in your specific classroom. Use the same teaching formula: explain, model, practise, feedback. Do this systematically, not casually.
Second, implement a reward system. This might be a simple behaviour chart, a token jar where the class earns stickers and cashes them in for rewards, or individual reward systems for students who need more frequent feedback. The key is that rewards are frequent, visible, and valued.
Third, respond to misbehaviour briefly and calmly. PBIS does not mean no consequences; it means consequences are tied to teaching. A student calls out during a lesson. A PBIS response is: "Hands up, thank you," (stating the expectation), then during a calm moment later, "I noticed you called out when you knew the answer. I see your enthusiasm. Next time, raise your hand and I will call on you so everyone gets a turn." This takes 20 seconds, not ten minutes of lecturing.
Fourth, track behaviour to see who needs extra help. Keep a simple tally or checklist. Which students are off-task consistently? Which are not showing respect to peers? Which are struggling to manage frustration? These students are candidates for a conversation about what they need.
A Year 4 teacher implements classroom PBIS. She teaches expectations in week one, focusing on "Respect" (listening, kind words), "Responsibility" (doing your best, asking for help), and "Trying" (it is okay to get it wrong; mistakes help us learn). She starts a simple token reward: students earn a token for showing expectations, ten tokens earns a choice of activity. She praises specifically and frequently. During a maths lesson, a student rushes through a problem and gets it wrong. The teacher calmly says, "That is a smart mistake. Let us talk about it." The student realises his error and fixes it. A peer watches and realises trying means not giving up. By October, off-task behaviour has dropped from 20% of observation points to 5%, and students ask her for help instead of giving up.
PBIS vs Traditional Discipline
PBIS differs from typical discipline in theory and results. Traditional methods view misbehaviour as a choice, met with punishment. PBIS, however, sees behaviour as learned (Sugai & Horner, 2006) and teaches. These are key differences (Skiba & Peterson, 1999).
| Aspect | PBIS | Traditional Discipline |
|---|---|---|
| Underlying belief | Behaviour is learned. Students can be taught. | Behaviour problems are choices or defiance. Punishment deters. |
| Strategy | Teach expectations proactively. Reinforce frequently. Support students who struggle. | React to rule-breaking. Punish. Assume students know the rules. |
| Ratio of positive to corrective | 5:1 or higher. Emphasise what you want to see. | Often 1:1 or reversed. Focus on what is wrong. |
| Data use | Track ODRs. Identify patterns. Adjust support based on data. | Anecdotal. Respond to incidents as they happen. |
| When a student breaks a rule | Brief consequence plus re-teaching. Calm adult response. | Punishment (detention, suspension). Often emotional adult response. |
| Who needs intensive support | Identified by data (ODRs). Offered before suspending. | Often identified only after multiple suspensions. Too late. |
| Equity outcomes | Reduces disparities in discipline (students of colour, students with SEN suspended less). | Increases disparities. Students of colour suspended 3x more; students with disabilities 4x more. |
| Impact on academics | Improved attendance and grades because students are in class and engaged. | Worse academics. Suspension removes time on task and increases likelihood of drop-out. |
PBIS schools see big changes. Horner et al. (2009) showed 20-40% fewer discipline referrals. Academic results rose 20-30%, especially for learners with disabilities. School safety and climate improved too. PBIS also shrinks discipline gaps (Horner et al., 2009).
Losen and Whitaker (2018) found traditional discipline harms vulnerable learners. Schools suspend learners with undiagnosed ADHD or autism for failing to meet expectations. Learners with different communication styles are punished for "disrespect," but should be taught. This exclusion increases the school-to-prison pipeline (Losen & Whitaker, 2018).
A secondary school switched from zero-tolerance discipline to PBIS. In year one, they explicitly taught expectations, tracked ODRs by demographic group, and discovered that students with disabilities had 5x more referrals than non-disabled peers. Rather than concluding the students were "worse," they provided Tier 2 and Tier 3 support. By year two, the referral gap narrowed to 1.5x. Academic outcomes improved for all students, particularly students with SEN. Suspensions dropped from 120 per year to 15.
Common PBIS Mistakes
Researchers (e.g., Sugai & Horner, 2009) found schools may fail with PBIS. Incomplete implementation (Bradshaw et al., 2009) can lead to abandonment (Fixsen et al., 2005). Understand common errors to help your learners benefit.
Mistake 1: Teaching expectations once and expecting they will stick. Expectations need to be taught in week one, re-taught in week four, refreshed in January, and reinforced throughout the year. Many schools teach once and then wonder why students do not remember. Schedule explicit teaching like you would a curriculum.
Mistake 2: Reward systems that are inaccessible. A reward system where only high-achieving, well-behaved students earn rewards is not PBIS; it is unfair. PBIS rewards should be accessible to all students, including those who are struggling. A student might earn a reward for trying (not giving up) rather than succeeding. The reward should help them, not reinforce they are already good.
Mistake 3: Not tracking who is receiving recognition. Without data, the same students (usually those who are already well-behaved) get praised and rewarded repeatedly, while struggling students get ignored or corrected. Keep a simple tally sheet. Make sure you have praised every student, including those who are quiet and compliant but do not excel.
Mistake 4: Skipping the three-tier model. Some schools implement only Tier 1 (whole-school expectations) and then use harsh consequences for the few students who do not respond. This misses the entire point of PBIS. If a student is not responding to Tier 1 and expectations teaching, they need Tier 2 support, not a harsher punishment.
Mistake 5: Not collecting data. A school says they use PBIS but does not track ODRs or examine which students are struggling. They cannot be data-driven if they are not collecting data. Even a simple spreadsheet is better than nothing.
Mistake 6: Not involving all staff. A headteacher and a few teachers enthusiastically implement PBIS while the rest of the staff ignores it. Students learn quickly that some teachers will enforce expectations and others will not. Consistency across all adults is essential.
Mistake 7: Over-relying on points and prizes. Some schools implement PBIS by starting with expensive reward systems. While rewards help, the real power is in the teaching of expectations and the praising of good behaviour. A school without a token system but with excellent explicit teaching and consistent praise will outperform a school with a fancy reward app but poor teaching.
The first school taught PBIS expectations initially (Sugai & Horner, 2009). Enthusiasm dropped; staff stopped teaching and praising. Rewards seemed costly, and PBIS ended. They forgot ongoing teaching and staff training. The second school scheduled teaching, trained everyone, and focused on basics. They improved consistently (Bradshaw et al., 2009).
Getting Started with PBIS
If your school is not implementing PBIS, you can start in your classroom. If your school is beginning PBIS, here is a realistic roadmap.
Agree on your school's most vital learner behaviours. Observable, teachable actions are best, say researchers (e.g., "Respect, Responsibility, Safety"). Avoid abstract concepts that are hard to define or demonstrate.
Step 2: Build a teaching matrix. Create a table showing what each expectation looks like in each setting (classroom, hall, playground, lunch, transitions). Make it concrete. "Respect in the classroom means listening when others speak, using kind words, and staying in your seat." Do not assume students know this.
Step 3: Schedule expectations teaching. Block out time in week one to teach expectations explicitly. Plan to re-teach in week four, before half-term, after Christmas, and in the summer term. Make it part of your calendar. Do not treat it as something extra to fit in.
Step 4: Implement a reward system. This can be simple (praise and recognition) or more elaborate (points, token jars, certificates). Make sure rewards are frequent and accessible. Ask students what would motivate them rather than guessing.
Step 5: Aim for the 5:1 ratio. Count your praise statements for one week. Are you praising five times for every correction? If not, consciously increase praise. Look for good behaviour and name it. Use specific language. This shift is the single most impactful change many teachers make.
Step 6: Collect data. At school level, track Office Discipline Referrals. At classroom level, use a simple checklist or observation form. Which students are meeting expectations consistently? Which are struggling? Use this information to decide who needs Tier 2 support.
Step 7: Implement Tier 2 for students not responding to Tier 1. Do not jump to harsh consequences. Offer a small group social skills session, check-in/check-out, or one-to-one mentoring. Monitor whether they improve. If they do not within four weeks, move to Tier 3 (Functional Behaviour Assessment and Behaviour Intervention Plan).
Step 8: Review progress. At the end of the term, review your ODR data. Are discipline referrals decreasing? Are more students showing expected behaviours? Are you seeing improvement in attendance and academics? Use this information to refine your approach for next term.
For classroom teachers implementing PBIS alone, start with Steps 1 through 5 above. The core work is teaching expectations, praising consistently, and using a reward system that is accessible. These three elements will improve behaviour in your classroom significantly. Move to data collection (Step 6) once you are confident with the first five steps.
PBIS schools need a leadership team (principal, SENCo, teachers, TAs, supervisors). Commit to two years before judging results. Year one builds skills, systems, and data use. Year two refines and expands support (Horner et al., 2009). Evaluating year one is too early (Sugai & Horner, 2006).
A Year 2 teacher with no schoolwide support decides to implement classroom PBIS. She identifies three expectations (Respect, Responsibility, Trying), explains them in week one, and teaches them explicitly using role-play. She commits to the 5:1 praise ratio. She starts a simple token jar; when the jar is full, the class gets 15 minutes of extra playtime. She tracks which students are struggling using a simple checklist. By October, behaviour has improved markedly. Off-task time dropped from 25% to 8%. Two students who were frequently in trouble (Aisha and Marcus) are now meeting expectations consistently because they feel successful when praised for small improvements. This teacher has not waited for the school to implement PBIS; she has used PBIS principles and seen rapid results.

PBIS teaches behaviour systematically, using data (Sugai, 2007). It is not a quick fix or simple reward system. This framework supports all learners, especially those who struggle (Horner, 2005). When done well, behaviour improves, and gaps narrow (Simonsen, 2008; Bradshaw, 2009). Schools then become safer and learners feel valued (Sugai, 2016).
