We present findings from an analysis of tests of teacher mathematical knowledge identified over a 20-year period of mathematics education literature. This analysis is part of a larger project aimed at developing a repository of instruments and their associated validity evidence for use in mathematics education. We report on how these tests are…

Drawing from the developmental and cognitive mathematics literature, the purpose of this study was to investigate the reliability, validity, and diagnostic utility of a widely-researched number line task in kindergarten. Specifically, the Number Line Assessment 0-100 (NLA 0-100) as compared to an established kindergarten screening measure was…

We report on the construction and validation of the Young Children's Math Anxiety Scale (YCMAX), a developmentally appropriate measure of math anxiety intended for kindergarten students. We administered the YCMAX to a sample of public school kindergarteners (N = 355) and conducted factor analyses to examine its structure. A two-factor solution…

This manuscript presents the results from a study to investigate the technical characteristics of two versions of a number line assessment (NLA 0-20 and NLA 0-100). The sample consisted of 60 kindergarten and 46 first grade students. Both number line versions had sufficient alternate form and test-retest reliability. The NLA 0-20 had low and the…

This study assessed the psychometric properties of a digital early mathematics assessment, the Ani Banani Math Test (ABMT) in three samples (N[subscript 1] = 243, N[subscript 2] = 691, N[subscript 3] = 1282) in kindergarten and first grade (age range 4.67-7.30). Confirmatory factor analyses showed that the ABMT appears to measure one general…

This study aimed at (a) constructing a reliable and valid test to assess Ecuadorian 4-5-year olds' number and arithmetic skills; (b) providing empirical data on Ecuadorian 4-5-year olds' number and arithmetic skills; and (c) confronting these children's actual performances with the performances expected by national experts in this domain. We…

The purpose of this study was to examine six early numeracy measures used to monitor the mathematics progress of kindergarten and first-grade students. Seventy-one kindergarten students and 75 first-grade students were administered the measures each week. Delayed-alternate form reliability was adequate for instructional decision making on some…

Development of the Common Core State Standards (CCSS), and the creation of the Smarter Balanced Assessment Consortium (Smarter Balanced) and the Partnership for Assessment of Readiness for College and Careers (PARCC), changes the pattern of accountability testing. These changes raise the question: "How should NAEP's validity and utility be…

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…

In the following technical report, we present evidence of the technical adequacy of the easyCBM[R] math measures in grades K-2. In addition to reliability information, we present criterion-related validity evidence, both concurrent and predictive, and construct validity evidence. The results represent data gathered throughout the 2009/2010 school…
