While numerous studies show positive immediate effects of pre-k (Reception), studies also show that these effects usually fade as soon as kindergarten or first grade (Year 1 and Year 2). To discover if consistency in programming from pre-school to elementary (primary) school can extend these positive effects, Virginia Knechtel and colleagues at Mathematica Policy Research (MPR) recently performed the first randomised study of the effectiveness of The Knowledge is Power Program (KIPP) pre-school on second graders (Year 3) who had continued with the KIPP programme into elementary school.
KIPP is a network of 200 elementary and secondary charter schools serving 80,000 pupils in the US, most of whom are low-income and African American or Latino. Admission to KIPP is via lottery. KIPP schools emphasise academics and character development in safe environments that foster pupils’ progression to further education. As part of an i3 scale-up grant, MPR performed a randomised study on the effects of KIPP on elementary to high school pupils, and found positive, statistically significant effects for KIPP pupils. For the pre-school study, the researchers drew their population sample from pupils in the 2015 study who had started KIPP in pre-K (n=97), comparing them to pupils who did not win the KIPP lottery and attended other schools (n=147). At the end of second grade (Year 3), when most pupils had attended KIPP for five years, both reading and maths scores were higher on subtests of the Woodcock-Johnson for KIPP pupils than for control pupils (ES=+0.43 on Letter Word ID, +0.21 for Passage Comprehension, +0.34 for Applied Problems and +0.31 for Calculation). This is not a lasting effect of pre-k, but the cumulative impact of everything KIPP schools did in grades pre-K-2 (Reception to Year 3).
Authors interviewed school staff and identified six key factors that differed between KIPP and non-KIPP programmes. These included that the schools’ structures allow for continuity among year groups, KIPP pre-K is academically focused, and there is a conscious effort to build relationships between school staff and pupils’ families.

The evidence of the effects of state-funded pre-kindergarten (preschool) programmes in the US was recently reviewed by a task force of scientists from the Brookings Institute and Duke University. These findings were released in a report called “The Current State of Scientific Knowledge on Pre-Kindergarten Effects”. Following the evidence review, the task force released a consensus statement outlining conclusions and recommendations about the effects of state-funded pre-kindergarten. According to the report:
- Greatest improvements at the end of the pre-kindergarten year are more often found for pupils from low-SES backgrounds or who are dual language learners than for their higher-SES and English-proficient peers.
- Not all pre-k programmes are equally effective, and this may be influenced by several factors. Positive influences include using evidence-based programmes that are well-implemented; utilising ongoing professional development and coaching for teachers; and promoting classrooms with predictable routines and positive, supportive pupil-teacher relationships.
- Pre-k environments are most effective when pupils’ individual abilities, knowledge and backgrounds are considered, and teaching strategies and content accordingly adjusted.
- Children who attend pre-k demonstrate more school readiness at the end of the year than those who do not, especially in the areas of literacy and numeracy.
- Long-term effects of pre-k in the later elementary (primary)years are inconclusive.
- More complete and reliable evidence is needed, during and after pre-k programmes, to create and sustain pre-kindergartners’ long-term gains.
The full report goes into more detail about the consensus statements, and discusses the results of the evidence with regards to funding, policy and other considerations.

Stanford University’s Center for Research on Education Outcomes (CREDO) has released findings from a new study on school closures. The report, authored by Chunping Han and colleagues, systematically examines closure of low-performing charter and traditional public schools (TPS) in the US. A main goal of the study was to see whether children whose schools had been closed for poor performance do better or worse in their new schools.
The authors used existing longitudinally linked data that CREDO had developed in partnership with 26 state education agencies. They identified low-performing, full-time, regular (non-alternative) schools and closures in those 26 states from academic year 2006-07 to 2012-13. A total of 1,522 low-performing schools, including 1,204 TPS and 318 charters, were closed in the 26 states during the study period. To measure academic performance across the low-performing schools, the authors used scores from state standardised achievement tests.
Key findings of the study included:
- A little less than half of displaced closure pupils landed in better schools.
- In both the charter and traditional public school sectors, low-performing schools with a larger share of black and Hispanic pupils were more likely to be closed than similarly performing schools with a smaller share of disadvantaged minority pupils.
- The quality of the receiving school made a significant difference in post-closure pupil outcomes. Closure pupils who attended better schools post-closure tended to make greater academic gains than did their peers from not-closed low-performing schools in the same sector, while those ending up in worse or equivalent schools had weaker academic growth than their peers in comparable low-performing settings.

A multi-year scale-up study has examined the effectiveness of Open Court Reading (OCR), a phonics-based curriculum for grades K-6 (Reception to Year 7).
The study, by Michael Vaden-Kiernar and colleagues, and published in the Journal of Research on Educational Effectiveness, was a school-level, cluster randomised trial, involving around 4,500 pupils and 1,000 teachers in 49 elementary schools across the US.
The OCR curriculum includes pupil materials, teacher manuals, diagnostic and assessment tools and test preparation practice guides. In all grades (K-5), the instructional format is a three-part lesson with specific instruction in phonemic awareness and phonics, vocabulary and comprehension skills and writing skills. The programme includes one- or two-day summer workshops at the start of each school year to train teachers on programme implementation, and ongoing support by OCR reading consultants.
An implementation study showed adequate to high levels of fidelity to the programme. However, there were no statistically significant effects on reading performance in Year 1, and a small negative effect (effect size = -0.09) in Year 2. Relative to the “business-as-usual” controls, no positive overall impacts of OCR and mixed impacts for pupil subgroups were found.

What difference do smaller class sizes, and more teachers, make in early childhood education (ECE)?
A meta-analysis by Jocelyn Bowne and colleagues, published in Educational Evaluation and Policy Analysis, attempts to find some answers. The analysis included evaluations of ECE programs in the US between 1960 and 2007. The evaluations were either experimental studies, used a high-quality quasi-experimental design, or showed baseline equivalence of treatment and control participants. In total, 38 studies were included, all of which looked at children ages 3 to 5 years old attending an ECE center for 10 hours a week or more for at least 4 months. Child-teacher ratios ranged from 5:1 to 15:1 and class sizes from 11 to 25.
The findings were as follows:
- Above a child–teacher ratio of 7.5:1, changing the ratio had no effect on children’s cognitive and achievement outcomes. Below this, a reduction of the ratio by one child per teacher predicted an effect size of +0.22.
- For class sizes greater than 15, increasing the size of the class had little effect on children’s cognitive and achievement outcomes. Below this, one child fewer in the class size predicted an effect size of +0.10.
The authors caution that these findings are correlational, rather than causal, so changing class sizes or ratios, certainly at scale, may not lead to these results. However, they conclude that “very small and/or well-staffed classrooms might confer some small benefits for children’s cognitive and academic learning”.

An SRI Education evaluation of the New Teacher Center’s (NTC’s) induction model shows some positive results on pupil achievement in mathematics and English language arts (reading, writing, and linguistic/communication skills).
The NTC induction model provides new teachers with two years of coaching from a trained mentor. New teachers meet with their assigned mentor for a minimum of 180 minutes each month and work through a programme of NTC-developed support. The evaluation, conducted by Rebecca Schmidt and colleagues, reports on findings from a three-year randomised controlled trial of NTC’s induction model in two US school districts (one in Florida and the other in Illinois). New teachers in participating schools were randomly assigned to receive either the NTC induction model (the treatment condition) or business-as-usual new teacher support (the control condition).
Pupils in grades 4–8 (Years 5–9) who were taught by teachers who had participated in NTC induction for two years did better in English language arts (effect size = +0.09) and maths (effect size = +0.15) compared to pupils of control teachers.
