The challenge of "educational" assessments--assessments that advance the purposes of learning and instruction--is to provide useful information regarding students' progress towards the goals of instruction in ways that are reliable and not idiosyncratic. In this commentary, the author indicates that the challenges are actually more…

In this technical report, we provide the results of a series of studies on the technical adequacy of the early reading measures available on the easyCBM[R] assessment system. The results from the two-level hierarchical linear growth model analyses suggest that the reliability of the slope estimates for the easyCBM[R] reading measures are strong,…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…

A 2.5-year longitudinal study of the reading scales of the Stanford Achievement Test confirmed the redundancy in its subtests. Strong and stable test-retest reliability coefficients were evident and supported the use of the Stanford total reading scale for longitudinal evaluations. (Author)

An item analysis of the Stanford Achievement Test performance of about 12,000 students in schools and classes for the hearing impaired is presented. Tables show the percentage of correct answers to each question, as well as a summary of the responses for each sub-test and major categories within some sub-tests. Because the test was developed for…
