A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

The Computer-based Orthographic Processing Assessment (COPA) is a newly developed assessment to measure orthographic processing skills, including rapid perception, access, differentiation, correction, and arrangement. In this study, cognitive diagnostic models were used to test if the dimensionality of the COPA conforms to theoretical expectation,…

Parent-teacher relationship (PTR) quality is linked to child and family-school functioning and may be especially important in the school adjustment of autistic children. However, measurement of PTR quality has been limited by inconsistency in the use of measures, a paucity of two-informant measurement, and limited psychometric consideration. We…

In this report I share the results of a document-based, comparative case study aimed at increasing our understanding about the potential utility of state kindergarten entry assessments (KEAs) to provide evidence of English learner (EL) kindergartners' knowledge and skills and, in turn, inform kindergarten teachers' instruction. Using a sample of 9…

Measuring program outcomes is required for documenting effectiveness of interventions with youths participating in programs funded through the U.S. Department of Agriculture's Children, Youth, and Families at Risk (CYFAR) initiative. The California CYFAR program provided programming for youths aged 5-8, which necessitated the development of an…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

We describe the psychometric evaluation of the "Elementary Social Behavior Assessment" (ESBA™), a 12-item scale measuring teacher-preferred, positive social skills. The ESBA was developed for use in elementary school classrooms to measure teacher perceptions of students using time-efficient, web-based data collection methods that allow…

This study examined the dimensionality and measurement invariance of the Kindergarten Student Entrance Profile (KSEP), a brief screening tool designed for use as a universal school readiness assessment. Teachers rated the readiness of 10,031 children during the first month of kindergarten in four ethnically diverse, medium-sized school districts…

We investigated the latent factor structure of the "Phonological Awareness Literacy Screening for Kindergarteners" in Spanish ("PALS español K"). Participants included 590 Spanish-speaking, public-school kindergarteners from five states. Three theoretically-guided factor structures were measured and tested with one half of our…
