Language Summary 2020  \nEducation  \nTargeted school-based interventions improve achievement in reading and maths for at-risk students in Grades 7-12  \nSchool-based interventions targeting students with, or at risk of, academic difficulties in Grades 7-12 have on average positive effects on standardised tests in reading and maths. The most effective interventions have the potential to considerably decrease the gap between at-risk and not-at-risk students. Effects vary substantially between interventions, however, and the evidence for using certain instructional methods or targeting certain domains is weaker.  \nWhat is this review about?  \nLow levels of literacy and numeracy skills are associated with a range of negative outcomes later  \nin life, such as reduced employment, earnings and health. This review examines the effects of a broad range of school-based interventions targeting students with, or at risk of, academic difficulties on standardised tests in reading and maths. Included interventions changed instructional methods by, for example, using peer-assisted learning, introducing financial incentives, giving instruction in small groups, providing more progress monitoring, using computer-assisted instruction, and giving teachers access to subject-specific coaching.  \nSome interventions targeted specific domainsin reading and maths, such as reading comprehension, fluency and algebra, while others focused on building for example meta-cognitive and social-emotional skills.  \nSchool-based interventions targeting at-risk students in Grades 7-12 improve performance on standardised tests in reading and maths.  \nWhat is the aim of this review?  \nThis Campbell systematic review examines the effects of targeted school-based interventionson standardised tests in reading and maths. The review analyses evidence from 71 studies, 52 of which are randomised controlled trials.  \nWhat studies are included?  \nIncluded studies examine targeted school-based interventions that tested effects on standardised tests in reading and maths for students in Grades 7-12 in regular schools. The students either have academic difficulties, or are deemed at risk of such difficulties on the basis of their background. The interventions are targeted as they aim to improve achievement for these groups of students, and not all students.  \nThe review summarises findings from 71 studies. Of these, 59 are from the USA, four from Canada, three from the UK, two from Germany, two from the Netherlands, and one from Australia.  \nFifty-two studies are randomised controlled trials and 19 are quasi-experimental studies.  \nWhat are the main findings ofthis review?  \nThe interventions studied have on average positive and statistically significant short-run effects on standardised tests in reading and maths. This effect size is of an educationally meaningful magnitude, for example, in relation to the gap between groups of at-risk and not-at-risk students. This means that the most effective interventions have the potential of making a considerable dent in this gap.  \nOnly seven included studies tested effects more than three months after the end of intervention, and there is therefore little evidence of longer-run effects.  \nEffects are very similar across reading domains. Interventions have larger effects on standardised tests in maths than on reading tests. Small group instruction has significantly larger effect sizes than computer-assisted instruction and incentive components.  \nWhat do the findings ofthis review mean?  \nThe review provides support for school-based interventions for students with, or at risk of, academic difficulties in Grades 7-12. However, the results do not provide a strong basis for prioritising between earlier and later interventions. For that, estimates of the long-run cost-effectiveness of interventions would be needed.  \nThe lack of long-run evidence should not be confused with a lack of effectiveness.
