Transitional Kindergarten (TK) is a relatively new model of early childhood education, with little evidence on whether and how it affects children's development. This study provides new evidence using data from Michigan, which has the nation's second-largest TK program. Using survey data (N=171) from administrators in 2021-2022, the paper…

School districts in northeastern Tennessee have had persistently low proficiency rates in grade 3 English language arts, which were exacerbated by disruptions in schooling due to the Covid-19 pandemic. In response, the Niswonger Foundation, a technical assistance provider that supports these districts, developed Project On-Track, a high-dosage,…

Transitional kindergarten (TK) is a relatively recent entrant into the US early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on third-grade test scores. Using an augmented regression discontinuity design, we find that TK improves third-grade…

Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on 3rd grade test scores. Using an augmented regression discontinuity design, we find that TK improves 3rd grade…

Public preschool boosts academic skills in kindergarten, but little is known about whether that boost lasts to third grade because many studies stop directly assessing children after kindergarten. The current study tests for sustained associations between preschool attendance and an array of repeatedly measured, directly assessed language and math…

This study evaluated the effectiveness of faithful use of Imagine Math, a computer adaptive math intervention for elementary students in grades three through five. To achieve this objective, the researcher compared the math achievement growth as measured by the NWEA MAP math assessments from fall 2021 to spring 2022 between the treatment group and…

This study investigated the costs of different summer reading programs and compared costs to the benefits of summer school as a way to avoid retaining students not reading proficiently at the end of third grade. Per pupil costs ranged from US$1,665 to US$2,194. The average cost was US$1,887 (range: US$266-US$5,552) with 82% of overall expenses…

Inquiry-based science interventions aim to improve students' science proficiency by helping them understand scientific processes. In these interventions, students conduct hands-on investigations of science concepts and everyday phenomena, construct explanations for what they observe, consider alternative explanations, and communicate and justify…

Purpose: This study examines the impact of the Amira Learning AI-powered reading platform on literacy outcomes for elementary students in 12 school districts in Louisiana during the 2023-24 school year. Methodology: Employing a quasi-experimental design aligned with the Every Student Succeeds Act Level II (Moderate Evidence) standard, a…

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…

This quantitative, causal-comparative study aims to examine the academic performance of all third-grade students who participated in after-school tutoring from English Language Arts (ELA) in comparison to those who did not, using the results from the 2022-2023 Mississippi Academic Assessment Program English Language Arts (MAAP ELA) assessment. The…

Pioneer Valley Books (PVB) contracted McREL International to investigate the effects of the third grade Literacy Footprints (LFP) guided reading system on English language arts (ELA) performance on state assessments. LFP is a research-based, comprehensive, small-group literacy tool that facilitates explicit and systematic guided reading…

Purpose: In this study, we investigated the effects of a schoolwide program, Bookworms K-5 Reading and Writing, on student achievement. Method: The study included seven cohorts of students (N = 8,806) in grades 2-5 in 17 elementary schools across three school years. We used a comparative interrupted time-series design, conducting multilevel growth…
