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…

The Early Literacy Program focuses on the development of early literacy skills, with additional emphasis placed on intervention for students at risk of not meeting grade-based reading benchmarks. Resources available to aid these students include interventions and supports for students in grades kindergarten through third grade, standards and…

The "Experimental Evaluation of the Tools of the Mind Pre-K Curriculum" study was designed to compare the effectiveness of the "Tools of the Mind" ("Tools") curriculum to the curricula the school system is currently using in enhancing children's self-regulation skills and their academic preparation for kindergarten.…

This technical report is an addendum to a study we initially reported on in 2014 (Wray, Lai, Saez, Alonzo, & Tindal, 2014). In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from the Wray et al study. This supplementary report presents the results of the…

The experimental evaluation of the "Tools of the Mind Pre-K Curriculum" described in this report was designed to examine the effectiveness of the "Tools of the Mind" ("Tools") curriculum for enhancing children's self-regulation skills and their academic preparation for kindergarten when compared to the usual…

This technical report provides detailed information about the sample, survey instruments, and resultant data for the 2022 American Instructional Resources Surveys (AIRS) that were administered to principals and teachers in spring 2022 via the RAND Corporation's American Educator Panels (AEP). The 2022 AIRS focused on the usage of, perceptions of,…

This report summarizes the results of a scale-up project funded by the Institute of Education Sciences in 2006. "Scaling up TRIAD: Teaching Early Mathematics for Understanding with Trajectories and Technologies" was a project that took a preschool mathematics intervention to scale across three sites, following children from their…

This in-brief technical report documents the results from two different analytic approaches for examining the reliability of the slope for easyCBM® math measures in Grades K-8. Results varied by grade, assessment measure, and the analytic approach. Results patterns are discussed.

In this technical report, we present the results of a study to gather criterion-related evidence for Grade K-1 easyCBM® reading measures. We used correlations to examine the relation between the easyCBM® measures and other published measures with known reliability and validity evidence, including the Dynamic Indicators of Basic Early Literacy…

aimswebPlus® is an assessment, data management, and reporting system that provides national and local performance and growth norms for the screening and progress monitoring of math and reading skills for all students in kindergarten through 8th grade. aimswebPlus uses two types of measures: (1) "curriculum-based measures" (CBMs)--brief,…

We report the results of an alternate form reliability and criterion validity study of kindergarten and grade 1 (N = 84-199) reading measures from the easyCBM© assessment system and Stanford Early School Achievement Test/Stanford Achievement Test, 10th edition (SESAT/SAT-­10) across 5 time points. The alternate form reliabilities ranged from…

Within a response to intervention (RTI) framework, students are administered multiple tests of equivalent difficulty. Changes in students' scores over time are then attributed to changes in learning. In the current study, we evaluated the reliability of score changes (i.e., slope) for the easyCBM[R] letter names, word reading fluency, and passage…

Previous norms for the easyCBM assessment system were computed using scores from all students who took each measure for every grade and benchmark season (fall, winter, and spring). During the 2013-­14 school year, new national norms were developed to more accurately (proportionately) represent reading and mathematics performance by two variables:…

In compliance with the Texas Education Code, the Houston Independent School District (HISD) has provided free prekindergarten classes for eligible Houston area four-year old students since the 1985-1986 scholastic year. The program curriculum focuses on beginning literacy, numeracy, and socio-emotional development, supporting the individual…
