Reading has been at the forefront of early-grade educational interventions, but addressing the educational needs of students in math early on is also critical given that early gaps in math skills widen further over the course of schooling. In this study, we examine the effects of Kentucky's Math Achievement Fund -- a unique state-level program…

The purpose of this study was to examine the academic impact of two distinct tutoring approaches implemented in a public elementary school in Virginia. The study focused on two tutoring models: a collaboratively designed university-based program that leverages pre-service teachers for in-school tutoring and a state-funded after-school initiative,…

While policymakers have demonstrated considerable enthusiasm for "science of reading" initiatives, the evidence on the impact of related reforms when implemented at scale is limited. In this pre-registered, quasi-experimental study, we examine California's recent initiative to improve early literacy across the state's lowest-performing…

Michigan's Great Start Readiness Program (GSRP) is a state-funded pre-K program that serves at risk four-year-old children across the state. Utilizing longitudinal data from 1,394 children in a mid-sized urban school district, we conducted regression analyses and piecewise linear growth models to examine the growth trajectory of GSRP children and…

We systematically examine the existing evidence and compute meta-analytic averages for the effects of scaled-up, publicly funded pre-kindergarten (pre-K) programmes in the United States on student mathematics and reading achievement. The analysis is restricted to experimental and quasi-experimental research designs with the highest internal…

This study drew data from a randomized trial of a statewide prekindergarten program in Tennessee and presents new evidence on the impacts of preK on third-grade achievement using administrative data on children's neighborhood environments. Results indicate that preK had no measurable impact on children's third-grade math achievement regardless of…

Math Teachers' Circles (MTCs) bring math teachers and university mathematicians together to engage in collaborative mathematical activity. Currently there are over 110 MTCs across 40 states. A key claim is that MTCs are "communities of practice." However, to date there has been no research to substantiate this claim. In this paper, we…

The Massachusetts Department of Elementary and Secondary Education (DESE), like other state education agencies, recognizes that a key lever to turning around low-performing schools is the quality of instruction and thus embeds a schoolwide instructional quality measure into its monitoring process. Massachusetts' schoolwide quality instruction…

Traditionally, teacher salaries have been determined solely by experience and educational attainment. This has led to chronic shortages of teachers in particular subject areas, such as math, science and special education. We study the first long-running statewide program to differentiate teacher pay based on subject area, Georgia's bonus system…

The purpose of this evaluation study was to examine children's longitudinal academic and social outcomes associated with attendance in Georgia's Pre-K Program and to examine the quality of the classrooms attended. This report covers pre-k to 4th grade outcomes collected between the 2013-2014 and 2018-2019 school years as well as a sub-study…

We investigate the effects of a statewide program designed to increase the supply of teachers in designated "hard-to-staff" areas, such as special education, math, and science. Employing a difference-in-difference estimator we find that the loan forgiveness component of the program was effective, reducing mean attrition rates for middle…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. The major issue addressed by this type of study is around the benefits of offering children access to enrollment in NC Pre-K. An RCT is considered the…

North Carolina's Smart Start and More at Four (MAF) early childhood programs were evaluated through the end of elementary school (age 11) by estimating the impact of state funding allocations to programs in each of 100 counties across 13 consecutive years on outcomes for all children in each county-year group (n = 1,004,571; 49% female; 61%…

Several states have changed their statewide achievement tests over the past 5 years. These changes may pose difficulties for educators tasked with identifying students in need of additional support. This study evaluated the stability of decision-making accuracy estimates across changes to the statewide achievement test. We analyzed extant data…

The Every Student Succeeds Act (ESSA) requires states to identify and turn around struggling schools, with federal school improvement money required to fund evidence-based policies. Most research on turnarounds has focused on individual schools, whereas studies of district-wide turnarounds have come from relatively exceptional settings and…
