Sound assessment tools are needed to evaluate effects of mathematics interventions that familiarize children with early mathematics concepts before they enter the formal school system. We developed a short version of an existing early mathematics tool based on analyses of data collected in a nationally representative Danish sample. Research…

Indicators of academic achievement for bilingual students can be inaccurate due to linguistic heterogeneity. For indigenous populations, language shift (the gradual replacement of one language by another) is a factor that can increase this heterogeneity and poses an additional challenge for valid testing. We investigated whether and how indigenous…

The present study examined the technical adequacy of curriculum-based measures (CBMs) of early numeracy. Six 1-min early mathematics tasks were administered to 137 kindergarten and first-grade students, along with an omnibus test of early mathematics. The CBM measures included Count Out Loud, Quantity Discrimination, Number Identification, Missing…

The Preschool Behavioral and Emotional Rating Scale (PreBERS) is an assessment of emotional and behavioral strengths in preschoolers with well-established reliability and validity for educational and clinical application in children with and without disabilities. The present study provides further evidence of psychometric rigor for items and…

In administration of individually administered intelligence tests, items are commonly presented in a sequence of increasing difficulty, and test administration is terminated after a predetermined number of incorrect answers. This practice produces stochastically censored data, a form of nonignorable missing data. By manipulating four factors…

This study describes the dimensionality and continuum of Spanish phonological awareness (PA) skills in 3- to 6-year-old children. A 3 x 4 factorial design crossed word structure of test items (word, syllable, phoneme) with task (blending multiple-choice, blending free-response, elision multiple-choice, elision free-response) to assess 12 PA…

Determining the cross-cultural equivalence of multilingual tests is a challenge that is more complex than simple horizontal equating of test forms. This study examines the functioning of a trilingual test of preschool readiness to determine the equivalence. Different forms of the test have previously been examined using classical statistical…
