Acelero 2011-12 Program Evaluation—Summary Report
June 1, 2013 Assessment • Outcomes
This report presents the results from the second year of NIEER’s evaluation of Acelero students’ learning in language and general conceptual knowledge and early math skills.
The results presented in this report are from the second year of NIEER’s evaluation of Acelero students’ learning in two areas: language and general conceptual knowledge, as measured by the Peabody Picture Vocabulary Test (PPVT), and early math skills, as measured by the Applied Problems subtest of the Woodcock Johnson Tests of Achievement (WJ-AP). In addition to measuring overall growth, authors Steve Barnett and Kwanghee Jung examined relationships between learning gains and children’s personal and family characteristics, program structure, curriculum, assessment system used, classroom process as measured by CLASS observations, and teacher characteristics.
