Clarke, Ben; Strand Cary, Mari G.; Shanley, Lina; Sutherland, Marah – Grantee Submission, 2020
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…

Martinez, Rebecca S.; Missall, Kristen N.; Graney, Suzanne Bamonto; Aricak, O. Tolga; Clarke, Ben – Assessment for Effective Intervention, 2009
The current study examines the technical adequacy of four Early Numeracy Curriculum-Based Measurement (EN-CBM) screening tasks: "Oral Counting" (OC), "Number Identification" (NI), "Quantity Discrimination" (QD), and "Missing Number" (MN). Results from 59 kindergarten students assessed in the fall and spring reveal moderate to high test-retest and…
