In the last issue of Best Evidence in Brief, we included a PISA in Focus review on performance-based pay for teachers. This US study from the RAND Corporation also looks at performance pay, but specifically at the effects of rewarding teams of teachers. The study, which used a randomised design, included 159 teams of teachers teaching pupils in grades 6 to 8 (KS3) in nine schools. Teachers on selected teams had the opportunity to earn a bonus based on their pupil’s growth in achievement in mathematics, English language arts, science, and social studies.
The study showed that the intervention had no effect on pupil achievement, teacher practices, or teacher attitudes. Pupils taught by teacher teams who were offered incentives scored slightly better on some standardised tests, but the differences were small and not statistically significant.

Pupils who went to summer school had improved their literacy performance at the end of the summer. This randomised trial, from Early Childhood Research Quarterly, examined the effects of a summer literacy programme on struggling readers in the US where summer holidays are longer.
Overall, pupils who didn’t attend summer school showed mean declines in the reading of nonsense words (a standard test of fluency) of approximately five words per minute over the summer. Children who attended summer school at the end of Kindergarten (Year 1) had a fluency gain of approximately 12 words-per-minute. Pupils at the end of Grade 1 (Year 2) had a fluency gain of 7.5 words per minute.
The findings are generally consistent with previous studies of summer school effects and the summer learning outcomes of children, and suggest that summer school can be a useful strategy to support learning over the summer months.

This guide from the Coalition for Evidence-Based Policy summarises five well-conducted, low-cost randomised controlled trials (RCTs) carried out in real-world community settings. As the guide states, RCTs are regarded as the strongest method for evaluating programme effectiveness. Evaluations of the Triple P (Positive Parenting Programme) system and New York City’s teacher incentive programme are reviewed. The purpose of the guide is to illustrate the feasibility and value of low-cost RCTs for policy makers and researchers.
