What is it?
Behaviour interventions seek to improve achievement by reducing challenging behaviour. This entry covers interventions aimed at reducing a variety of behaviours, from low-level disruption to aggression, violence, bullying, substance abuse and general anti-social activities. The interventions themselves can be split into three broad categories:
- approaches to developing a positive school ethos or improving discipline across the whole school which also aim to support greater engagement in learning;
- universal programs which seek to improve behaviour and generally take place in the classroom; and
- more specialised programs which are targeted at students with specific behavioural issues.
Other approaches, such as Parental engagement and Social and emotional learning programs, are often associated with reported improvements in school ethos or discipline, but are not included in this summary, which is limited to interventions that focus directly on behaviour.
How effective is it?
Evidence suggests that, on average, behaviour interventions can produce moderate improvements in academic performance along with a decrease in problematic behaviours. However, estimated benefits vary widely across the categories of program described above. Impacts are larger for targeted interventions matched to specific students with particular needs or behavioural issues than for universal interventions or whole school strategies. School-level behaviour approaches are often related to improvements in achievement, but there is a lack of evidence to show that the improvements are actually caused by the behaviour interventions, rather than other school interventions happening the same time. Parental and community involvement programs are often associated with reported improvements in school ethos or discipline and so are worth considering as alternatives to direct behaviour interventions.
Approaches such as improving teachers’ behaviour management and students’ cognitive and social skills seem to be equally effective.
The majority of studies report higher impact with older students. There is some anecdotal evidence about the benefits of reducing problematic behaviour of disruptive students on the achievement of their classmates, but this is an understudied dimension in evaluations of behaviour programs.
How secure is the evidence?
Overall, it is clear that reducing challenging behaviour in schools can have a direct and lasting effect on students’ learning. This is based on a number of meta-analyses that review robust studies of interventions in schools.
Some caution is needed in interpreting the headline finding as the majority of the meta-analyses of behaviour interventions focus on students diagnosed with specific emotional or behavioural disorders, not on low-level classroom disruption. Further research is needed to investigate links between universal approaches to improving general classroom behaviour and better learning outcomes.
One meta-analysis of an anger management intervention shows a positive effect on behaviour but an overall negative effect on learning. This implies that careful targeting and evaluation is important, and demonstrates that it is possible to reduce problematic behaviour without improving learning.
What are the costs?
Costs will be highly dependent on the type of intervention. Teacher-led behavioural interventions in the classroom are the least expensive (the only cost is likely to be that of relevant continuing professional development for the teachers) but the also least effective. One to one support is more expensive but more effective (about $40 per hour, or $600 per student for 15 sessions). The cost rating presented here relates to the cost of the more intensive interventions. Overall, costs are estimated as moderate.
What should I consider?
Targeted interventions for those diagnosed or at risk of emotional or behavioural disorders produce the greatest effects.
Programmes of two to six months seem to produce more long-lasting results.
The wide variation in impact suggests that schools should look for programs with a proven track record of impact.
Have you considered what training and professional development is required for any programs you plan to adopt?
Have you explored how to involve parents or communities in behaviour programs? This appears to increase impact.
