Matthew A Kraft and colleagues conducted a meta-analysis of the causal evidence on the effect of teacher coaching on teaching and learning. Their paper, published in the Review of Educational Research, reviewed 60 studies on teacher coaching programmes conducted after 2006 that measured the impact of teacher coaching on either teaching (measured using tools such as the Classroom Assessment Scoring System or the Early Language and Literacy Classroom Observation) or pupil academic performance (measured by standardised tests).
Their results found that sustained coaching improves both classroom teaching and pupil achievement, with pooled effect sizes of +0.49 standard deviations for teaching and +0.18 standard deviations for academic achievement.
However, the effectiveness of a teacher coaching programme seems to be determined by the number of participants. When studies were divided into programmes that had fewer than 100 participants and those that had more than 100 participants, the impact on teaching was nearly double for the smaller programmes than for programmes with more than 100 participants. For pupil achievement, the smaller programmes showed an impact of nearly three times that of the larger programmes.

Franziska Egert and colleagues in Germany and Amsterdam have conducted a review of the effects of professional development (PD) for early childhood educators on programme quality and children’s educational outcomes.
Studies were only included if they addressed quality of child care or child development, included early childhood teachers (including preschool, kindergarten and centre-based care), were quantitative, were experimental or quasi-experimental, reported effect sizes or data and addressed children 0–7 years old. This yielded 36 studies of 42 programmes evaluating quality ratings, and nine studies of 10 programmes evaluating both quality ratings and pupil outcomes.
Results showed that professional development improved the external quality ratings (as evaluated using the Classroom Assessment Scoring System, Early Language and Literacy Classroom Observation, Environmental Rating Scales and Individualized Classroom Assessment Scoring System) of early childhood education (effect size=+0.68), with programmes providing 45–60 PD hours having the greatest impact on classroom practice as compared to programmes offering fewer or more hours. This was true regardless of whether teachers held a university degree or not. Further, programmes that solely used coaching were almost three times as effective as other programmes. A second meta-analysis of a subset of studies (n=486 teachers, 4,504 children) showed that improvement in the quality of early childhood education programmes was correlated with improvements in child development (effect size=+0.14) as determined by language and literacy scores, maths scores, social-behavioural ratings, and assessment of cognition, knowledge and school readiness.

An evaluation of the Challenge the Gap (CtG) programme for the Education Endowment Foundation found no evidence that the programme increased average achievement for either primary or secondary pupils overall.
Challenge the Gap is a two-year school improvement programme that aims to help schools improve the achievement of their disadvantaged pupils through a professional development programme for staff. The evaluation conducted by The University of Manchester, involved 21,041 pupils from 104 schools (64 primary schools and 39 secondary schools). Around 24% of pupils in the primary schools and 16% in the secondary schools were eligible for free school meals. The evaluation assessed the impact on all participating schools using 2015 Key Stage 2 or Key Stage 4 results. CtG schools were compared to schools with a similar socio-demographic profile.
No evidence was found that CtG increased the average achievement for either primary or secondary school pupils, overall. For children eligible for free school meals (FSM), those in CtG primary schools made two months’ additional progress (average effect size = +0.10) compared to similar children in non-CtG schools. In CtG secondary schools, FSM-eligible pupils made two months’ less progress compared to similar pupils in non-CtG secondary schools (average effect size = -0.10). The smaller number of FSM-eligible pupils in the trial means that these results are less secure than the overall findings.

Joseph Taylor of Abt Associates and colleagues conducted a rigorous study of the Science Teachers Learning Through Lesson Analysis (STeLLA) professional development (PD) programme.
STeLLA is designed to increase elementary (primary) teachers’ science knowledge. Instead of the standard practice of teaching pupils to memorise science concepts and then perform activities that prove these concepts, STeLLA teachers lead pupils to discover science concepts through experience and experimentation. One of STeLLA’s main tenets is to have pupils think through science problems aloud so that teachers can respond to pupils’ ideas and guide them to scientific conclusions and specific learning goals. Its other distinguishing feature is that during the course of a year, groups of 5–10 teachers led by a PD coach watch and critique videos of experienced science teachers’ lessons, later moving on to their own and their colleagues’ lessons, to analyse them regarding science content, teaching and learning. In addition, STeLLA teachers are taught by university-level science teachers the summer prior to implementation to provide them with greater science content knowledge, a process called “content deepening”.
In the current study, researchers used a cluster-randomised design to compare STeLLA to The Content Deepening Program, a PD programme that deepens teachers’ science knowledge through university faculty-led science teaching, like STeLLA does, but without STeLLA’s analysis-of-practice component. Seventy-seven schools, with 144 teachers and 2,823 fourth and fifth grade pupils (Years 5 and 6) in Colorado, were randomly assigned either to STeLLA (n=42 schools) or to The Content Deepening Program (n=35 schools) in two cohorts, the first in 2011–12 and the second in 2012–13. Teachers in both conditions experienced 88 hours of PD and had the same learning goals for their pupils. Pupils were pre- and post-tested on a science measure based on established assessments. Although the control group demonstrated a slight achievement advantage at baseline, results showed that pupils in STeLLA classes scored higher (effect size = +0.55) at post-test than pupils in classes whose teachers had been through The Content Deepening Program.

Developing Mathematical Ideas (DMI) is a professional development programme designed to increase teachers’ knowledge of fourth grade (Year 5) maths fractions and rational numbers with the ultimate goal of improving their pupils’ maths achievement.
A study conducted in the 2014–15 school year, prepared for the Institute of Education Sciences by Madhavi Jayanthi and colleagues at Instructional Research Group and REL Southeast, investigated the effects of DMI on teacher content knowledge and their pupils’ subsequent achievement in fractions. A total of 264 fourth grade (Year 5) teachers in 84 elementary (primary) schools in Florida, Georgia and South Carolina in the US were randomly assigned by school to receive either DMI (n=42 schools, 129 teachers) or their usual professional development programme (n=42 schools, 135 teachers). The 84 schools were matched on grade four enrolment, number of pupils who exceeded fourth grade maths standards, percentage of African American and Hispanic pupils and percentage of pupils eligible for free- or reduced-price lunches. In autumn 2014, DMI teachers received eight three-hour training sessions conducted over four days, followed by homework and concluding with a test on fractions. A total of 4,204 fourth grade pupils’ (2,091 E, 2,113 C) baseline scores on third grade standardised tests were used as a pre-test, because most third graders know little about fractions and the Test for Understanding of Fractions was used as the post-test at the end of the academic year to measure their knowledge gain after their teachers had completed DMI.
Results showed no significant differences between either the DMI or non-DMI teachers’ knowledge of fractions and their pupils’ proficiency in fractions.

A new evaluation report by Michael S Garet and colleagues, published by the US Institute of Education Sciences, examines the impact of providing elementary (primary) school teachers with content-focused maths continuing professional development (CPD) on their knowledge, teaching, and students’ achievement.
The study’s CPD had three components totalling 93 hours. The core of the CPD was Intel Math, an 80-hour workshop delivered in the summer of 2013 that focused on deepening teachers’ knowledge of grades K–8 mathematics (Years 1 to 9). Two additional CPD components totalling 13 hours were delivered during the 2013–14 school year.
The study’s sample included grade 4 (Year 5) teachers from 94 schools in six US school districts and five states that were randomly assigned within schools to either a treatment group that received the study CPD or a control group that did not receive the study CPD.
Key findings were as follows:
- The CPD had a positive impact on teacher knowledge. On average, treatment teachers’ maths knowledge scores on a study-administered maths assessment were 21 percentile points higher than control teachers’ scores in spring 2014, after the CPD was completed.
- The CPD had a positive impact on some aspects of teaching practice, particularly Richness of Mathematics, which emphasises the conceptual aspects of maths, such as the use and quality of mathematical explanations.
- Despite the CPD’s generally positive impact on teacher outcomes, the CPD did not have a positive impact on student achievement. On average, treatment teachers’ students scored 2 percentile points lower than control teachers’ students in spring 2014 on both a study-administered maths assessment aligned with the content of the CPD and the state maths assessment. This difference was statistically significant for the state maths assessment but not for the study-administered assessment.
