Purpose: Measuring the growth of young children's vocabulary is important for researchers seeking to understand language learning as well as for clinicians aiming to identify early deficits. The MacArthur-Bates Communicative Development Inventories (CDIs) are parent report instruments that offer a reliable and valid method for measuring early…

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,…

Touch-screen tablets are used in the classroom for assessment. Little is known about the psychometric properties of tablet-based assessments. This study examined the validity and reliability of an expressive and receptive assessment app designed to measure literacy skills. Children (N = 45; 3-5 years) completed the app assessments for alphabet and…

The present contribution aims at presenting an assessment tool (i.e., the TALK-assessment) built to evaluate the language development and school readiness of Italian preschoolers before they enter primary school, and its predictive validity for the children's reading and writing skills at the end of the first year of primary school. The early…

Pragmatics has been a key component of language competence frameworks. While the majority of second/foreign language (L2) pragmatics tests have targeted productive skills, the assessment of receptive pragmatic skills remains a developing field. This study explores validation evidence for a test of receptive L2 pragmatic ability called the American…

This article describes the development and validation of the new CATSS (Computer Adaptive Test of Size and Strength), which measures vocabulary knowledge in four modalities -- productive recall, receptive recall, productive recognition, and receptive recognition. In the first part of the paper we present the assumptions that underlie the test --…

Latinx dual language learners (DLLs) are an enormous and growing student body that faces educational adversities and inequities. One of the most salient findings to emerge from decades of educational research is that DLLs who close the gap with their monolingual peers and have the best long-term academic performance are those who develop strong…

The American Sign Language Comprehension Test (ASL-CT) is a 30-item multiple-choice test that measures ASL receptive skills and is administered through a website. This article describes the development and psychometric properties of the test based on a sample of 80 college students including deaf native signers, hearing native signers, deaf…

Computer-based and standardized administration of the Test of Word Knowledge were compared for 30 adolescent subjects with learning disabilities. The total, receptive, and expressive composites were higher for the standard administration. Results indicated the need for independent norms for computer-based adaptations of standardized language…
