We use data from a large-scale experiment conducted in Indiana in 2009-2010 to examine the impact of two interim assessment programs (mCLASS and Acuity) across the mathematics and reading achievement distributions. Specifically, we focus on whether the use of interim assessments has a particularly strong effect on improving outcomes for low…

This study operationalizes four measures of instructional differentiation: one for Grade 2 English language arts (ELA), one for Grade 2 mathematics, one for Grade 5 ELA, and one for Grade 5 mathematics. Our study evaluates their measurement properties of each measure in a large field experiment: the Indiana Diagnostic Assessment Tools Study, which…

The What Works Clearinghouse (WWC) has updated its 2009 intervention report for SuccessMaker®, a set of computer-based courses designed to supplement regular K-8 reading instruction. The program is designed to improve skills in areas such as concepts of print, phonological awareness, phonics, fluency, vocabulary, comprehension, grammar, and…

Recent work that has examined the impact of what are variously called periodic, interim, benchmark, or diagnostic assessments, typically administered three or four times during a school year, has produced mixed findings. For instance, one study reported small significant effects in mathematics in grades 3-8, but not in reading (Carlson et al.,…

The interpretation of Indiana Public Law 109 and subsequent policy adopted by the Indiana Department of Education resulted in the Indiana State Board of Education mandating circumstances implemented during the 2011-2012 school year regarding grade level retention of Grade 3 students. IREAD-3, a standardized, gateway assessment, was administered to…
