District and state education leaders frequently use screening assessments to identify students who are at risk of performing poorly on end-of-year achievement tests. This study examines the use of a universal screening assessment of reading skills for early identification of students at risk of low achievement on nationally normed tests of reading…

Given the serious consequences of making ill-fated admissions and funding decisions for applicants to graduate and professional school, it is important to rely on sound evidence to optimize such judgments. Previous meta-analytic research has demonstrated the generalizable validity of the "GRE"® General Test for predicting academic…

A recurrent trend in higher education research has been to identify additional predictors of college success beyond the traditional measures of high school grade point average (HSGPA) and standardized test scores, given that a large percentage of unaccounted variance in college performance remains. A recent study by Wyatt, Wiley, Camara, and…

In this technical report, we document the results of a cross-validation study designed to identify optimal cut-scores for the use of the easyCBM[R] mathematics test in the state of Washington. A large sample, randomly split into two groups of roughly equal size, was used for this study. Students' performance classification on the Washington state…

This technical report presents results from a cross-validation study designed to identify optimal cut scores when using easyCBM[R] reading tests in Oregon. The cross-validation study analyzes data from the 2009-2010 academic year for easyCBM[R] reading measures. A sample of approximately 2,000 students per grade, randomly split into two groups of…

This report summarizes research findings and implementation practices for teacher and principal value-added models (VAMs), as a first step in the Team Pennsylvania Foundation's (Team PA) pilot project to inform the development of a full, statewide model evaluation system. We have selected 21 studies that represent key issues and findings in the…

This report is meant to help juvenile courts develop practical risk-screening instruments. Courts increasingly are using some method of risk classification to assist in assignment of youth to differential service/supervision programs. A comparison of commonly used or advocated risk classification methods may provide courts with guidance in…

In an effort to continuously monitor the validity of the SAT for predicting first-year college grades, the College Board has continued its multi-year effort to recruit four-year colleges and universities (henceforth, "institutions") to provide data on the cohorts of first-time, first-year students entering in the fall semester beginning…

In this study, two statistical approaches for adjusting grades were tested on data obtained from four law schools, with samples of 157, 188, 206, and 191. These approaches were previously validated using data on undergraduates but have not been used in a study of postgraduate performance. Neither method yielded consistent improvements in the…

This study was designed to examine questions about the validity and utility of two commonly used predictors of academic success in law school, the Law School Admission Test (LSAT) score and the undergraduate grade point average (UGPA), when the criterion measure is grade point average at the completion of law school (LGPA). The study also examined…

This study investigated the relationship between the scales used for the NMSBA assessments and the RIT scales used to report performance on Northwest Evaluation Association tests. The study estimated the changes in reading and mathematics RIT score equivalents for the NMSBA performance levels in those subjects. Test records for more than 17,000…

This study was designed to address questions of differential validity and questions of differential prediction in the law school admission process. The former were evaluated by comparing the magnitude of validity coefficients resulting from both simple and multiple correlations between first-year performance in law school and the traditional…

Recently NWEA completed a project to connect the scale of the WKCE with NWEA's RIT scale. Six Wisconsin school systems participated in the study, using test information from a group of over 1,500 students enrolled in fourth, eighth, and tenth grade who took both the WKCE and NWEA tests in the fall of 2003. Information from these tests was used in…

Each year, Montana students participate in testing as part of the state's assessment program. This past spring, students in grades 4, 8, and 10 took Montana Comprehensive Assessment System (MontCAS) tests in reading and mathematics. These tests serve as an important measure of student achievement for the state's accountability system. Results from…

Each year, Nevada students in grades 3, 4, 5, and 7 participate in testing as part of the Nevada assessment program. Students in grades 3 and 5 take the Nevada Criterion Referenced Assessment (Nevada CRT) while students in grades 4 and 7 take the Iowa Test of Basic Skills (ITBS). These tests serve as an important measure of student achievement for…
