Introduction
Rewards and sanctions are among the most discussed and most contested tools in school behaviour management. Every school has them. Research on their effectiveness is substantial, nuanced and, at times, contradictory. Practice varies enormously, from highly structured token economies to informal, relationship-based systems to the largely punitive approaches associated with certain high-profile school models.
This article explores what the evidence says about how rewards and sanctions work, what makes them effective or counterproductive, and how school leaders can design systems that genuinely serve the culture they are trying to build rather than operating as a parallel, bureaucratic layer that students learn to navigate around.
The Purpose of Rewards and Sanctions
It is worth starting with first principles. The purpose of a reward, in a school context, is not to bribe students into compliance. It is to communicate clearly and publicly what the school values, to reinforce the behaviours that contribute to the school's culture and to celebrate the individuals who exemplify it. The purpose of a sanction is not punishment for its own sake. It is to signal clearly that certain behaviour falls below the school's standards, to create a consequence that makes that signal meaningful and to give the student concerned the opportunity to understand why the behaviour was unacceptable and what is expected instead.
When both rewards and sanctions are understood in these terms, some common practices immediately reveal their limitations. A reward that is given so frequently it loses its meaning is no longer communicating anything. A sanction that is applied without explanation, in a way the student experiences as arbitrary or unfair, is creating resentment rather than understanding. And a system that relies heavily on sanctions while treating rewards as secondary has inverted the balance that the research suggests is most effective.
What the Research Says About Rewards
The research base on rewards in school behaviour management is broadly supportive of their use, with important qualifications. A DfE research report on pupil behaviour (2012) found that reward systems, including token economies and merit-based recognitions, showed evidence of effectiveness, particularly with younger students and with students experiencing emotional and behavioural difficulties.

UK research on pupils' perceptions of rewards and sanctions found that parental contact about good behaviour, positive comments on work and school reward trips were among the most universally effective rewards. What worked less well were rewards that felt impersonal, trivial or disconnected from genuine achievement. Students, particularly older ones, were more motivated by rewards that recognised real effort and real accomplishment than by those that felt like participation tokens.

This points to an important design principle: rewards work best when they are genuinely earned, clearly connected to the values and expectations of the school and experienced by students as meaningful recognition rather than administrative acknowledgement. A house point given for compliance feels different from a house point given for persisting with a genuinely difficult piece of work. Both may technically be rewards, but their cultural effect is not the same.
The Risk of Over-Reliance on Extrinsic Motivation
A significant body of research, drawing particularly on the self-determination theory of Ryan and Deci (2000), raises concerns about the long-term effects of external reward systems on intrinsic motivation. The argument, supported by laboratory and field research, is that introducing external rewards for behaviours that a person would otherwise engage in for their own intrinsic reasons can reduce the intrinsic motivation for that behaviour over time.
For school leaders, this research does not support the abandonment of reward systems; it supports their careful design. Rewards that are informational, that communicate genuine recognition of achievement, are less likely to undermine intrinsic motivation than rewards that are controlling, that communicate conditional approval contingent on compliance. The language, timing and framing of rewards matters as much as the rewards themselves.
Verbal praise, used specifically and descriptively, has demonstrated positive effects not only on those who receive it but on nearby students. Evidence-based guidance on classroom behaviour management recommends that teachers provide at least four praise statements for every reprimand. Schools whose culture is characterised by a significantly higher ratio of critical to affirming interactions have not only a less pleasant culture; they have a less effective one.

What the Research Says About Sanctions
Sanctions are necessary. The research does not support the view that consequences are inherently counterproductive or that a restorative-only approach is sufficient in all circumstances. Students need clear signals that certain behaviour falls below the community's standards, and those signals must carry genuine weight if the standards are to be credible. A sanction that has no practical effect is not a sanction; it is an administrative ritual that confirms to students that the rule it is supposed to protect is not real.
Research has identified certain sanctions as broadly effective. Detention, particularly where it involves a genuine loss of preferred time and a structured conversation about the behaviour that led to it, is widely used and broadly supported by evidence. Contact with home, particularly where the school has a positive relationship with parents and the contact is framed constructively, is found to be highly effective across age groups. Internal exclusion, used judiciously, can serve as both a consequence and a cooling-off structure.
Certain practices, however, are clearly counterproductive and should have no place in a well-designed behaviour system. Public shaming, whether through visible punishment in front of peers, callout systems that expose individual students to ridicule or exclusionary practices that single students out for sustained negative attention, does not improve behaviour. It damages the relationship between student and school, increases the likelihood of retaliatory or avoidance behaviour and, in some students, contributes to anxiety, depression and disengagement from education entirely. Lagos State, in its own formal guidance, has placed such practices within the category of physical and emotional harm, and the principle stands in any context: shame is not a behaviour management tool.

Consistency and the Code of Conduct
Perhaps the most important principle governing the effective use of both rewards and sanctions is consistency. A reward system that is applied differently by different staff members, or that is seen to favour some students over others, loses its ability to communicate genuine cultural values. A sanction system that operates at the discretion of individual teachers, without a shared code, produces exactly the inconsistency of expectation that research identifies as one of the most corrosive forces in school culture.
Rewards and sanctions should not be improvised. They should be set out clearly in the school's code of conduct, known to all members of the community and applied in a way that is consistent with that code. The code itself should be accessible to students, parents and staff, frequently referenced, and regularly reviewed to ensure it remains fit for purpose.
Research on student perceptions found that students' approval of rewards and sanctions systems was significantly higher in schools where the system was perceived to be consistently applied by all staff. In one study, consistently applied systems were associated with significantly more positive student attitudes not only towards the system itself but towards the school more broadly.

Connecting Sanctions to the Class Teacher
One structural principle that is both practically effective and culturally important is that each student's behaviour record, both rewards and sanctions, should be held and managed in relation to their class teacher or form tutor. This ensures that the person who has the deepest knowledge of and relationship with the student is the person who accumulates the picture of their conduct over time. It prevents behaviour management from becoming an anonymous administrative process, divorced from the relational context in which behaviour actually occurs.
When a student receives a sanction, it should not feel like a bureaucratic outcome of a system. It should feel like a response from an adult who knows them, cares about their progress and is holding them to a standard that applies to everyone in the community equally. This relational framing of both rewards and sanctions is one of the most powerful determinants of whether they actually change behaviour.
Designing the System: Practical Principles for School Leaders
Effective rewards and sanctions systems share several design features:
> • Clarity: every student and every member of staff knows what > behaviours are rewarded, what behaviours are sanctioned, and what the > range of consequences looks like at each level. > > • Proportionality: sanctions are graduated, with the most serious > responses reserved for the most serious behaviours. Minor > infringements do not attract the same response as deliberate, repeated > or seriously harmful conduct. > > • Transparency: the system is publicly available and consistently > referred to, so that its application is never experienced as > arbitrary. > > • Parity: the same standards apply to all students, regardless of > background, ability or history. Any departure from this principle, > however well-intentioned, undermines the cultural authority of the > system. > > • Regular review: the system is monitored and evaluated over time, > including against data on how rewards and sanctions are distributed > across different pupil groups. Systems that disproportionately > sanction disadvantaged students or fail to recognise their > achievements require urgent redesign. > > • Balance: the system recognises and celebrates good behaviour with > the same energy and visibility that it addresses poor behaviour. In > many schools, the sanction architecture is significantly more > elaborate than the reward architecture. This imbalance communicates, > tacitly but powerfully, that the school is more interested in what > students do wrong than in what they do right.
Examples in Practice
Rewards
House points, merit awards and public celebration in assemblies remain widely used and broadly effective when they are genuinely earned and publicly meaningful. Positive communication with parents, whether by phone, letter or through a school communication platform, is consistently rated by students as among the most valued forms of recognition. Appointment to roles of responsibility, whether as form representatives, subject ambassadors or mentors for younger students, rewards and develops simultaneously. Certificates, trips and treats retain their effectiveness when they are rare enough to be genuinely valued and clearly connected to real achievement.
Sanctions
Detention, used consistently and with a structured conversation component, is effective across age groups when it involves a genuine loss of preferred time. Report cards allow for close monitoring of individual students while providing a mechanism for targeted, incremental positive recognition. Internal exclusion, properly resourced and purposefully structured, can interrupt a pattern of behaviour without the disruption to learning that external exclusion causes. External exclusion, as a sanction of last resort for seriously harmful conduct, is necessary in some circumstances and must be applied in accordance with statutory guidance.
Throughout all of this, corporal punishment has no place in any school. In Nigeria, Lagos State has formally prohibited it as a form of physical abuse. In the UK it has been illegal in all schools for decades. Beyond legality, the evidence is clear that physical punishment does not improve behaviour in the long term and causes measurable psychological harm.
Conclusion
Rewards and sanctions, designed well, consistently applied and understood by the whole community, are among the most effective tools available to school leaders in the building and maintenance of a strong school culture. Designed poorly, applied inconsistently or used in ways that humiliate or disproportionately burden certain groups of students, they actively damage the culture they are supposed to serve.
The measure of a rewards and sanctions system is not its theoretical elegance. It is whether students experience it as fair, whether it changes behaviour, and whether it contributes to a school community in which every student feels genuinely valued and genuinely held to account. Those are not different things. They are the same thing.
