The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

This study is a secondary data analysis that extends knowledge about the effects of the early childhood Family Check-Up (FCU) intervention to trajectories of general psychopathology problems (p factor) across early and middle childhood, and effects on adolescent psychopathology and polydrug use. The Early Steps Multisite study (ClinicalTrials.gov…

Rasch and classification analyses on a field-test version of the third edition of the Assessment, Evaluation, and Programming System (AEPS-3), a curriculum-based assessment used to assess young children birth to age 6 years, were conducted. First, an evaluation of the psychometric properties of data from each developmental area of an AEPS-3…

This study examined Oregon's early intervention (EI) and early childhood special education (ECSE) pipelines as a function of children's intersecting ethnicity and home language(s) with a focus on children from Latino/a backgrounds with communication disorders. We found differences in children's referral source and age of referral, likelihood of…

Opportunities for practice play a critical role in learning complex behaviors. In the context of explicit mathematics instruction, practice facilitates systematic opportunities for students with mathematics difficulties (MD) to learn new mathematics content and apply such knowledge and skills to novel mathematics problems. This study explored…

The purpose of this article is to provide evidence of the technical adequacy of the Assessment, Evaluation, and Programming System--Third Edition (AEPS-3). The AEPS has long been identified as one of the most psychometrically sound early childhood curriculum-based assessments. In this article, results of three studies of technical adequacy are…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to…

This article discusses why and how states are integrating "DC:0-5™: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood" (DC:0-5) into state policy and systems; provides state examples to highlight some of the strategies that states have used to allow, promote, or require the use of…

This paper examined whether a younger starting age of formal instruction on a foreign language is beneficial in expanding circle countries. An experimental study was designed to examine to what extent the five varieties of English language teachers are intelligible to Japanese- (JSLs) and Korean-speaking language learners (KSLs), who have…

This study examined the cost-effectiveness of a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS. The study utilized a randomized block design with 1,251 at-risk students within 138 classrooms randomly assigned to one of two active treatment conditions (small groups of either two…

Parent-mediated interventions are cost-effective ways to increase access to appropriate treatment services to children with autism spectrum disorder. We aimed to engage parents working as partners within rural autism identification teams to facilitate prompt initiation of autism-specific treatment services and expand the amount of treatment…

A labor force of migrant farmworkers, mostly of Latino origin, largely support the agriculture industry in the US. While migrant labor is essential in the modern food system, food insecurity remains high among migrant farmworkers. Presented are the results from a survey on food insecurity, access, and farm to preschool involving 32 farmworker…

The COVID-19 pandemic tremendously disrupted ECE in the U.S., closing many private programs and nearly all public preschool and primary classrooms. To understand this impact, we used multiple strategies, including a nationwide survey of parents; a review of state policies, guidance and resource documents; and scans of media coverage to obtain…

Purpose: This study investigated the effects of enhanced milieu teaching (EMT) on caregiver implementation of language support strategies and child communication skills using a hybrid telepractice service delivery model. Method: Four caregivers and children with language delays aged 18-27 months participated in a multiple baseline across behaviors…

Universal screening is a critical component of school-based prevention systems. Screening data enable educators to target students for supplemental intervention, align resources to meet needs, and identify students who may be at risk for learning disabilities. One major requirement of the screening process is that all students are included to gain…
