MTSS vs RTI: What Teachers Need to Know
Teachers often hear MTSS and RTI used interchangeably, which creates confusion about what they actually do. The simple answer is that RTI (Response to.
What Is the Difference Between MTSS and RTI?
Teachers hear MTSS and RTI used similarly, causing confusion. RTI (Response to Intervention) supports academic interventions. MTSS (Multi-Tiered Systems of Support) includes RTI, behaviour plans, and social-emotional learning. RTI is part of a bigger MTSS picture.
Many schools use the term MTSS today because it describes the whole-child approach to support. For more on this topic, see Mtss rti teachers guide tiered. If your school says "We use MTSS," they are likely running RTI in the academic domain alongside behaviour and social-emotional systems. Understanding both terms helps you work through school documentation, IEP meetings, and intervention planning more effectively.
What Is RTI?
Response to Intervention (RTI) helps find learners needing academic support, especially in reading and maths. Tier 1 provides all learners with good classroom teaching. Tier 2 gives small group support to learners showing early difficulties (Fuchs & Fuchs, 2006). Tier 3 offers intensive individual help for learners not responding to Tier 2 (Vaughn & Fuchs, 2003).
Tiered support uses screening and tracks learner progress with goals. Screening tools like CBM help find learners needing support (Deno, 2003). Progress checks, every 1-2 weeks, show if interventions work (Fuchs & Fuchs, 1986). Schools refer learners not responding to special education evaluation (Batsche et al., 2005).
Fletcher and Vaughn (2009) note the US introduced RTI around 2004. IDEA allowed schools to use RTI data to spot learning difficulties. Previously, schools waited for learners to struggle significantly before acting. RTI changed this to address issues sooner.
Classroom example: A Year 2 teacher notices that three students are not keeping pace with phonics instructional approaches. Using CBM, she identifies their specific weakness in digraph recognition. She pulls them aside three times weekly for a 15-minute small-group lesson using a structured phonics program. After four weeks, she monitors their progress. If they are catching up, they return to whole-class instruction. If not, the school considers evaluation for special educational needs.
What Is MTSS?
MTSS links academic intervention (RTI) and behaviour support (PBIS) with social-emotional learning. This creates a coordinated system, as explained in Mtss rti teachers guide tiered. MTSS acknowledges learners need help in literacy, numeracy, behaviour, attendance and emotional control. Schools connect these areas instead of using separate programmes.
MTSS uses tiers across learning. Tier 1 gives all learners universal help (classroom rules, good teaching, character work). Tier 2 targets learners at risk (behaviour plans, social skills groups, reading help). Tier 3 supports learners in crisis (individual plans, maths tutoring, mental health referrals).
MTSS emerged in the early 2010s as educators recognised that RTI alone did not address the full picture of student need. A student might respond well to reading intervention but still struggle with behaviour and attendance. MTSS puts these systems in dialogue so that classroom teachers see the whole student (O'Neill & Stephenson, 2012).
The Year 2 teacher tracks phonics intervention learners and uses discipline data. She also monitors attendance and social skills, using a checklist. If a learner improves in reading but shows anxiety, the school provides support. This helps prevent struggles in multiple areas.
MTSS vs RTI: Side-by-Side Comparison
| Feature | RTI | MTSS |
|---|---|---|
| Scope | Academic skills only (reading, maths, writing) | Whole child (academic, behaviour, SEL, attendance, health) |
| Main Focus | Identifying and remediating reading and maths deficits | Coordinated support across multiple domains |
| Legal Basis | IDEA 2004 (special education identification) | Broader education reform (not a legal mandate) |
| Behaviour Support | Not included (separate from RTI) | Included (via PBIS or equivalent) |
| Data Types | Academic progress monitoring (CBM, assessments) | Academic, behaviour, attendance, social-emotional, discipline |
| Primary Outcome | Reduced disability referrals; earlier intervention | Reduced discipline, improved attendance, fewer referrals |
| Terminology Trend | Less common; still used in specialist literature | Increasingly common term across US schools |
| Teacher Role | Deliver Tier 1 instruction; monitor academic progress | Deliver Tier 1 instruction; monitor multiple domains; collaborate across teams |
How MTSS Expanded Beyond RTI
RTI was powerful but narrow. A school could run RTI perfectly and still have high suspension rates, chronic absenteeism, and students in crisis. Educators realised that academic progress was only one piece of the student experience. A student cannot learn if they are suspended, anxious, or hungry.
MTSS includes behaviour via PBIS. PBIS mirrors its tiered support, teaching expectations, supporting learners with early issues, and giving intensive help for chronic problems. SEL teaches emotional control, relationship skills, and decision-making (Durlak et al., 2011).
The key innovation of MTSS is the integration layer. Rather than having separate "RTI meetings," "PBIS meetings," and "counselling services," MTSS brings data from all domains into one system. A student struggling with reading might also have behaviour referrals and attendance issues. MTSS helps the school see these connections and coordinate support instead of treating them as separate problems.
MTSS improves outcomes, unlike RTI alone. A Year 5 learner shows maths progress but also has behaviour issues and absences. The behaviour specialist, teacher, and attendance officer meet. They find behaviour worsens when maths help is absent, suggesting anxiety. The school changes the schedule, adds support, and speaks with family. Six weeks later, behaviour, attendance, and maths all improve. (Example inspired by research, see e.g., Sailor, 2009; Sugai & Horner, 2009; Batsche et al., 2005).
The Role of Behaviour in MTSS
RTI prioritises academic help, not behaviour. MTSS, though, addresses behaviour directly. Schools often use PBIS (Sugai, Horner, & Gresham, 2008) within MTSS for behaviour. PBIS teaches behaviours, rewards good choices, and supports learners needing help (Simonsen et al., 2008).
PBIS mirrors RTI with a three-tier system. Tier 1 teaches all learners three core values (Sugai & Horner, 2006). Staff recognise positive behaviour and keep routines consistent (Simonsen et al., 2008). Tier 2 supports learners showing early warning signs. These include minor referrals and peer conflict (Walker et al., 1995). Learners get small group skills training (Lane et al., 2005). Tier 3 gives intensive support for chronic issues. Learners receive individual plans and assessments (Scott & Barrett, 2004).
MTSS schools use behaviour data alongside academic results. Teachers log behaviour referrals in a central system. The school analyses trends by learner, time, and setting. Then they adjust support (Bradshaw et al., 2008).
Classroom example: A primary school uses PBIS as part of MTSS. All staff teach the school value of "Respect" through specific routines (lining up calmly, waiting turns, listening without interrupting). Students who follow these routines earn positive recognition (stickers, notes home, public praise). When a Year 3 student shows early warning signs (two behaviour referrals in one week), the behaviour specialist offers Tier 2 support: weekly check-ins with a trusted adult, a visual schedule in the classroom, and recognition for meeting one specific self-advocacy goals (staying in seat during maths). This Tier 2 support prevents the student from needing a formal behaviour plan.
Data Systems in MTSS and RTI
Both RTI and MTSS rely heavily on data. RTI collects academic data: scores on reading fluency measures, maths facts tests, curriculum-based assessments. Teachers plot these data weekly on progress monitoring graphs. If the line shows improvement, the intervention is working. If the line is flat or declining, the teacher adjusts the intervention and may escalate to special education evaluation.
MTSS applies similar logic across areas. Schools record behaviour data, like suspensions (Sprick, 2016). They monitor attendance, such as absences (Gottfried, 2010). Schools gather SEL data, including emotional surveys (Brackett, 2016). Teachers view all data in a central dashboard (Sailor, 2009).
Schools use software like Illuminate, Schoolzilla, or Skyward for MTSS data. Teachers record learner progress, behaviour, and attendance in these systems. The software identifies learners needing Tier 2 or 3 support and prompts meetings. This differs from RTI, where teachers may keep data separately.
Classroom example: A secondary school uses an MTSS data system. Every Friday morning, each teacher enters grades and behaviour observations for students they taught that week. The system automatically identifies students with two or more behaviour referrals or failing grades in two or more classes. The school's MTSS team (principal, counsellor, RTI coordinator, behaviour specialist) reviews these flagged students in a 30-minute meeting. They decide which students need Tier 2 support and coordinate with teachers. By next Tuesday, the student is in a small-group class or has a check-in schedule. This rapid response prevents students from falling deeper into crisis.
Which Framework Does Your School Use?
RTI schools focus on academic intervention (reading and maths). You will see progress monitoring and special education discussions. RTI schools may have separate behaviour support systems. (Burns, VanDerHeyden, & Boice, 2008).
MTSS schools take a coordinated approach. They discuss data from multiple sources. Meetings include teachers, specialists, and counsellors. They discuss behaviour, attendance, social-emotional needs, and academics. Schools often see this integration as a strength (e.g. researchers [Names] and dates).
Many schools use the term MTSS but run RTI as the academic component. This is increasingly common, especially in districts that have updated their improvement plans. If you are unsure, ask your principal directly: "Are we implementing MTSS or RTI?" The answer tells you a lot about how the school views student support and where to focus your energy as a teacher.
Classroom example: A teacher in an RTI school notices that a student is struggling in reading intervention but receives no other support systems. The teacher refers the student for special education evaluation based on RTI data alone. In contrast, a teacher in an MTSS school notices the same reading struggle. However, they also see that the student has three behaviour referrals and poor attendance. The MTSS team meets and discovers that the student's parents are going through a separation. The school adds SEL support, a check-in with the counsellor, and a flexible homework plan before pursuing special education. The student may catch up without formal identification.
The Teacher's Role in Both Frameworks
RTI means you provide good Tier 1 teaching using proven methods and track learner progress. Give curriculum assessments to the team. Use specialist interventions and report back. Discuss learner progress in meetings, as per Fuchs & Fuchs (1986) and Deno (2003). Feedback on learner engagement aids decision-making, as noted by Batsche et al. (2005).
In MTSS, teachers deliver Tier 1 teaching and monitor learner behaviour (Sugai, 2002). They refer behaviour concerns to the central system (Horner, 2000). Teachers collaborate with specialists and deliver PBIS/SEL (Bradshaw, 2012). They attend meetings where data informs support decisions (Sailor, 2009).
MTSS needs more teamwork and clear communication for useful information. You stop working separately. If a learner struggles with learning, you quickly see behaviour or attendance issues. This means better support and stops intervention conflicting with crisis management (Adelman & Taylor, 2007).
Classroom example: An RTI-only teacher enters progress monitoring data into a spreadsheet and attends a monthly RTI meeting. She knows which students are in reading intervention. However, she has no idea that three of them have discipline referrals or chronic absence. In contrast, an MTSS teacher enters the same progress monitoring data into a dashboard alongside behaviour observations. When she enters data, she sees that a student is making progress in reading but has 12 absences. She mentions this in the MTSS weekly check-in. The attendance officer calls home and discovers the student has no transportation. The school arranges bus fare, and attendance improves within two weeks, which then boosts reading progress.
Common Misconceptions About MTSS and RTI
Misconception 1: MTSS means we stop doing RTI. False. MTSS includes RTI. When a school adopts MTSS, the academic intervention system (RTI) continues, but it is now coordinated with behaviour and SEL support. RTI is still used to identify students needing help with reading and maths.
RTI and MTSS support every learner, not just those with disabilities. Tier 1 provides universal support for all. PBIS, academic help, and SEL benefit all learners. MTSS prevents problems becoming severe; it does not replace special education.
MTSS is not just special education. It is a general framework (Batsche et al., 2005). Special education works with the MTSS team. General education leaders own MTSS, and it helps all learners. Some learners may need special education after MTSS. This happens through the MTSS process (Buffum et al., 2012).
Misconception 4: MTSS and PBIS are the same thing. False. PBIS is the behaviour component of MTSS. MTSS includes PBIS plus RTI plus SEL. A school can run PBIS without running RTI, but that school is not fully implementing MTSS. Think of PBIS as one piece of the MTSS puzzle.
Misconception 5: Interventions must be delivered by specialists only. False. Classroom teachers deliver most Tier 1 instruction and much Tier 2 support. Specialists help design and monitor interventions, but teachers are the primary delivery mechanism. If teachers do not buy in and use with fidelity, the whole system fails (Fuchs & Fuchs, 2006).
Misconception 6: More tiers are better. False. RTI and MTSS use three tiers because research shows this is effective. Some schools add a 'Tier 0' for prevention before Tier 1. Others add 'Tier 4' for crisis intervention after Tier 3. However, the basic three-tier model is the standard. Adding tiers often creates confusion and slows decision-making.
Key Takeaways
- MTSS is a comprehensive framework that encompasses RTI, not a replacement for it: Teachers should understand that RTI specifically addresses academic interventions, typically in reading and maths, while MTSS integrates these academic supports with behavioural and social-emotional learning interventions for a comprehensive approach to learner well-being and success (Sugai & Horner, 2006). This broader perspective ensures all aspects of a learner's development are considered within a tiered system of support.
- Effective implementation of both RTI and MTSS relies heavily on robust data collection and analysis: Regular progress monitoring and universal screening are fundamental to identifying learners needing support, evaluating intervention effectiveness, and making informed instructional adjustments (Fuchs & Fuchs, 2006). This data-driven approach ensures resources are allocated efficiently and interventions are tailored to specific learner needs.
- Classroom teachers are pivotal in the successful implementation of both RTI and MTSS: Teachers are responsible for delivering high-quality core instruction, conducting universal screening, implementing Tier 1 interventions, and collaborating with specialist staff to support learners across all tiers (Algozzine & Anderson, 2007). Their expertise in differentiating instruction and observing learner progress is indispensable for early identification and effective support.
- MTSS explicitly integrates behavioural and social-emotional support alongside academic interventions: Unlike RTI's primary focus on academic skills, MTSS provides a framework for addressing the whole child, recognising that behavioural and social-emotional challenges can significantly impact learning outcomes (Horner & Sugai, 2015). This integrated approach ensures that learners receive comprehensive support for all aspects of their development, fostering a positive school environment.
