Adams' equity theory explains how perceived unfairness affects pupil motivation and behaviour. This guide covers the input-output-referent model, the distinction between equity and equality in SEND contexts, and practical strategies for creating fair classroom systems.
Equity Theory, developed by John Stacey Adams in 1963, proposes that individuals are motivated by their perception of fairness in social exchanges. People compare the ratio of their inputs (effort, skill, time) to their outputs (rewards, recognition, grades) against the ratios of others around them. When they perceive an imbalance, they experience psychological discomfort and are motivated to restore equilibrium. In educational settings, this theory explains why a pupil who works hard but receives the same grade as a peer who barely tried may reduce their effort next time.
The theory has three core components. Inputs represent everything an individual contributes: effort, attendance, participation, prior knowledge, and natural ability. Outputs are the benefits received in return: grades, praise, recognition, opportunities, and personal satisfaction. Referents are the comparison points against which the individual judges fairness, typically peers in the same classroom or year group.
| Component | Inputs (What Is Given) | Outputs (What Is Received) | Classroom Example |
|---|---|---|---|
| Effort and Time | Homework completion, revision hours, lesson participation | Grades, verbal praise, written feedback | A pupil who revises for 3 hours expects a higher mark than one who did not revise at all |
| Skills and Prior Knowledge | Subject expertise, reading ability, prior learning | Stretch tasks, leadership roles, opportunities | A pupil with strong writing skills expects recognition through challenging extension work |
| Behaviour and Compliance | Following rules, helping peers, positive attitude | Trust, privileges, positive relationships | A well-behaved pupil notices a disruptive peer receiving more teacher attention |
Understanding equity theory helps teachers anticipate how pupils will respond to marking decisions, praise distribution, and resource allocation. A Year 9 pupil who watches a friend receive a merit for the same quality of work they submitted without recognition will feel a sharp sense of inequity, and that feeling affects subsequent effort and engagement more powerfully than any motivational speech.
Adams proposed that people do not evaluate fairness in absolute terms but through comparison. An individual calculates their own input-to-output ratio and then compares it against a referent, another person in a similar situation. If the ratios appear roughly equal, the individual experiences equity and is motivated to maintain their current level of contribution. If the ratios appear unequal, the individual experiences distress.
Adams identified two forms of perceived inequity. Under-reward inequity occurs when a person believes they contribute more (or receive less) than their comparison point. This typically produces anger, resentment, or withdrawal of effort. Over-reward inequity occurs when a person believes they receive more than they deserve relative to others. This produces guilt, though research suggests people tolerate over-reward more easily than under-reward.
When individuals perceive inequity, they respond in predictable ways: altering their inputs (working harder or less hard), attempting to change their outputs (requesting better treatment), cognitively distorting the situation ("Their work wasn't actually that good"), changing the referent (comparing themselves to someone else), or leaving the relationship altogether. In classrooms, this last option manifests as disengagement, task avoidance, or persistent absence.
The theory's strength is its recognition that motivation is not just about absolute reward levels but about perceived relative fairness. A pupil who receives a Grade 5 might be perfectly satisfied if their peers received similar grades, but deeply dissatisfied if a peer who did less work received the same grade. The comparison, not the grade itself, drives the emotional response.
Translating equity theory from workplace psychology into classrooms requires understanding the specific inputs, outputs, and referents that matter to pupils. While Adams developed the theory for organisational settings, its principles apply directly to any social exchange where effort and reward are visible, and classrooms are among the most transparent environments for this.
Pupils constantly assess whether teacher behaviour is fair. They notice who gets called on, whose hand is ignored, who receives praise, and who receives criticism. They track which pupils get extra time, which get easier tasks, and which seem to be "the favourite." These observations form their equity judgement, and that judgement influences their intrinsic motivation far more than external reward systems.
A Year 7 science teacher who consistently praises one table group while overlooking another creates an equity imbalance that the overlooked group will correct, typically by reducing effort. Similarly, a teacher who provides detailed written feedback on some essays but only ticks others communicates differential value, regardless of intent. Consistency in how feedback, attention, and recognition are distributed is one of the most important applications of equity theory in practice.
Assessment is the highest-stakes arena for equity perception. When pupils compare results, they are not just comparing grades; they are comparing the ratio of their perceived effort to their grade against the same ratio for their peers. A pupil who studied hard and received 70% will feel aggrieved if a friend who barely revised also received 70%. The grade is identical, but the equity calculation produces a sense of injustice.
Teachers can reduce this by making assessment criteria explicit (so pupils understand precisely what earns marks), using formative assessment that recognises effort and progress alongside attainment, and discussing openly how different types of effort, such as revision technique versus hours spent, produce different outcomes.
The distinction between equity and equality is one of the most important concepts for teachers, particularly those working with pupils who have special educational needs. Equality means giving everyone the same resources and opportunities. Equity means adjusting resources and opportunities so that everyone has a fair chance of success, recognising that some pupils face greater barriers than others.
| Concept | Definition | Classroom Example | SEND Implication |
|---|---|---|---|
| Equality | Everyone receives the same resources and treatment | All pupils complete the same worksheet in the same time | Pupils with learning difficulties fail because the task was not adapted to their needs |
| Equity | Resources are adjusted so everyone has a fair chance of success | Pupils receive differentiated tasks, scaffolding, or additional time based on need | Pupils with learning difficulties receive targeted support so they can access the same learning |
| Inclusion | Barriers are removed so all pupils belong and participate fully | The classroom environment, curriculum, and culture are designed with all learners in mind from the outset | Pupils with SEND are included as a starting assumption, not as an afterthought |
In practice, this distinction is crucial when other pupils ask why a classmate receives extra time, uses a laptop, or has different homework. Explaining equity, that different people need different things to succeed, is itself a valuable teaching moment. A Year 5 teacher might use the analogy of spectacles: we do not give everyone glasses, only those who need them. That is not unfair; it is equitable.
The Equality Act 2010 requires schools to make reasonable adjustments for disabled pupils, which is a legal expression of the equity principle. When a pupil with dyslexia receives coloured overlays and extra time, that is not special treatment; it is the adjustment needed to put them on a level playing field. Equity theory helps explain why some pupils may initially perceive these adjustments as unfair, and why explicit classroom discussion about different needs is so important.
Applying equity theory in your classroom means paying deliberate attention to how inputs, outputs, and comparisons operate among your pupils. The following strategies address the most common sources of perceived inequity in schools.
Share marking rubrics with pupils before they begin assessed work. When pupils understand what earns marks, they can more accurately judge the relationship between their input and their output. This reduces the sense that grades are arbitrary. In a Year 8 English class, projecting the success criteria alongside examples of work at different levels gives every pupil a clear picture of what is expected.
Explain openly that different pupils may receive different levels of support, and frame this as a strength of the classroom rather than preferential treatment. A teacher might say: "In this room, everyone gets what they need to do their best work. Sometimes that looks different for different people, and that is exactly how it should be." This normalises scaffolded support and reduces resentment.
Audit your praise patterns. Teachers often praise pupils who are naturally compliant or high-achieving while overlooking the effort of quieter or lower-attaining pupils. Keeping a simple tally over a week can reveal surprising imbalances. Aim to recognise effort and improvement, not just attainment, and ensure that praise reaches all areas of the classroom.
Give pupils regular opportunities to express how they feel about fairness in the classroom. This might be through anonymous feedback slips, structured circle time discussions, or one-to-one conversations. When pupils feel heard, their perception of equity improves even if the situation does not change immediately, because being consulted is itself an output that balances the equation.
Group tasks are a common source of inequity perception. Pupils who contribute most to a group project but receive the same grade as a peer who contributed little experience acute under-reward inequity. Strategies include individual accountability within group work (each member has a named role and assessed contribution), peer assessment of contribution, and designing tasks where individual input is visible alongside the collective outcome.
When pupils perceive inequity, they respond in predictable ways that teachers can learn to recognise and address before disengagement sets in. The most common responses are reduced effort ("Why should I bother if it makes no difference?"), confrontation (challenging the teacher or peers), psychological withdrawal (daydreaming, disengagement), and comparison-shifting (seeking out a new referent who makes the comparison more favourable).
Effective responses include conducting regular "equity audits" of classroom practices: reviewing who receives feedback, how quickly, and of what quality; examining behaviour management records for patterns of differential treatment; and reflecting on whether high-profile rewards (merits, prizes, public recognition) are reaching a broad range of pupils or clustering around the same individuals.
When a pupil raises a concern about fairness, taking it seriously is critical. Dismissing equity complaints ("Life isn't fair") confirms the pupil's internal working model that their inputs do not matter. Instead, acknowledge the concern, explain the rationale behind the decision, and, where appropriate, make adjustments. This does not mean giving in to every complaint; it means treating perceived inequity as legitimate data about your classroom climate.
Adams identified three core components that interact to produce equity or inequity perceptions in any social exchange.
Inputs are everything an individual contributes. In the classroom, pupil inputs include effort, attendance, participation, homework completion, behaviour, and willingness to take on challenges. Teacher inputs include lesson preparation, marking quality, emotional investment, and professional development. Crucially, what counts as an "input" is subjective: a pupil may believe their attendance alone is a significant contribution, while the teacher values effort and quality of work.
Outputs are the rewards and benefits received. For pupils, these include grades, praise, recognition, position in the class hierarchy, and the intrinsic satisfaction of learning. For teachers, outputs include salary, professional recognition, career progression, and the satisfaction of seeing pupils succeed. Again, the weighting of outputs is subjective: one pupil values grades above everything, while another values teacher approval.
Referents are the people against whom comparisons are made. Pupils typically compare themselves to classmates, siblings, or their own past performance. The choice of referent matters enormously: comparing yourself to the highest achiever in the class produces a different equity calculation than comparing yourself to a friend with similar ability. Teachers can influence referent choice by encouraging pupils to focus on personal progress rather than peer comparison, connecting to growth mindset principles.
This week, track your praise distribution across one day. Use a simple class list and add a tally mark each time you give a pupil verbal praise, written feedback, or public recognition. At the end of the day, examine the pattern. Most teachers discover significant clustering that they were completely unaware of. That single data point gives you a concrete starting point for building a more equitable classroom.
Equity Theory, developed by John Stacey Adams in 1963, proposes that individuals assess fairness by comparing their input-to-output ratio against the ratios of others. When the ratios are roughly equal, people feel motivated. When they perceive an imbalance, they experience distress and adjust their behaviour to restore equilibrium.
Make assessment criteria transparent so pupils understand the link between effort and outcome. Distribute praise and feedback consistently across all pupils, not just the highest achievers. Explain differentiated support openly, framing it as meeting individual needs rather than favouritism. Give pupils regular opportunities to voice their perceptions of fairness.
Equality means giving everyone the same resources and treatment. Equity means adjusting resources so that everyone has a fair chance of success, recognising that some individuals face greater barriers. In schools, the SEND Code of Practice and the Equality Act 2010 both operate on the equity principle: reasonable adjustments ensure pupils with disabilities can access learning alongside their peers.
Common mistakes include confusing equity with equality (treating everyone identically regardless of need), distributing praise unevenly without awareness, dismissing pupil concerns about fairness, and failing to explain the rationale behind differentiated provision. Teachers should also avoid assuming that their perception of fairness matches their pupils' perception.
Monitor engagement levels, effort, and willingness to participate. When pupils feel their contributions are fairly recognised, they typically maintain or increase effort. Regular pupil voice surveys, tracking praise distribution, and reviewing behaviour incident patterns all provide data on whether your equity practices are effective.

This meta-analysis of 183 justice studies confirms that perceived fairness strongly predicts satisfaction, commitment, and performance. The findings generalise to educational settings where pupils' sense of fair treatment predicts engagement and effort.
Equity Theory, developed by John Stacey Adams in 1963, proposes that individuals are motivated by their perception of fairness in social exchanges. People compare the ratio of their inputs (effort, skill, time) to their outputs (rewards, recognition, grades) against the ratios of others around them. When they perceive an imbalance, they experience psychological discomfort and are motivated to restore equilibrium. In educational settings, this theory explains why a pupil who works hard but receives the same grade as a peer who barely tried may reduce their effort next time.
The theory has three core components. Inputs represent everything an individual contributes: effort, attendance, participation, prior knowledge, and natural ability. Outputs are the benefits received in return: grades, praise, recognition, opportunities, and personal satisfaction. Referents are the comparison points against which the individual judges fairness, typically peers in the same classroom or year group.

A Year 9 pupil who watches a friend receive a merit for the same quality of work they submitted without recognition will feel a sharp sense of inequity, and that feeling affects subsequent effort and engagement more powerfully than any motivational speech.
Adams proposed that people do not evaluate fairness in absolute terms but through comparison. An individual calculates their own input-to-output ratio and then compares it against a referent, another person in a similar situation. If the ratios appear roughly equal, the individual experiences equity and is motivated to maintain their current level of contribution. If the ratios appear unequal, the individual experiences distress.
Adams identified two forms of perceived inequity. Under-reward inequity occurs when a person believes they contribute more (or receive less) than their comparison point. This typically produces anger, resentment, or withdrawal of effort. Over-reward inequity occurs when a person believes they receive more than they deserve relative to others. This produces guilt, though research suggests people tolerate over-reward more easily than under-reward.
When individuals perceive inequity, they respond in predictable ways: altering their inputs (working harder or less hard), attempting to change their outputs (requesting better treatment), cognitively distorting the situation ("Their work wasn't actually that good"), changing the referent (comparing themselves to someone else), or leaving the relationship altogether. In classrooms, this last option manifests as disengagement, task avoidance, or persistent absence.
The theory's strength is its recognition that motivation is not just about absolute reward levels but about perceived relative fairness. A pupil who receives a Grade 5 might be perfectly satisfied if their peers received similar grades, but deeply dissatisfied if a peer who did less work received the same grade. The comparison, not the grade itself, drives the emotional response.
Translating equity theory from workplace psychology into classrooms requires understanding the specific inputs, outputs, and referents that matter to pupils.
