Northwest Evaluation Association™ (NWEA™) is committed to providing partners with useful tools to help make inferences from Measures of Academic Progress® (MAP®) interim assessment scores. One important tool is the concordance table between MAP and state summative assessments. Concordance tables have been used for decades to relate scores on…

Concordance tables have been used for decades to relate scores on different tests measuring similar but distinct constructs. These tables, typically derived from statistical linking procedures, provide a direct link between scores on different tests and serve various purposes. Aside from describing how a score on one test relates to performance on…

Recently, Northwest Evaluation Association (NWEA) completed a study to connect the scale of the Minnesota Comprehensive Assessments (MCA) Testing Program used for Minnesota's mathematics and reading assessments with NWEA's RIT (Rasch Unit) scale. Information from the state assessments was used in a study to establish performance-level scores on…

Data from the ALEKS-based placement program at the University of Illinois is presented visually in several ways. The placement exam (an ALEKS assessment) contains precise item-specific information and the data show many interesting properties of the student populations of the placement courses, which include Precalculus, Calculus, and Business…

Recently, the Northwest Evaluation Association (NWEA) completed a study to connect the scale of the North Carolina State End of Grade (EOG) Testing Program used for North Carolina's mathematics and reading assessments with NWEA's Rausch Interval Unit (RIT) scale. Information from the state assessments was used in a study to establish…

In the following technical report, we present evidence of the technical adequacy of the easyCBM[R] math measures in grades K-2. In addition to reliability information, we present criterion-related validity evidence, both concurrent and predictive, and construct validity evidence. The results represent data gathered throughout the 2009/2010 school…

In this technical report, we present the results of a study examining the relation between the math measures available on the easyCBM[R] online benchmark and progress monitoring assessment system and the Oregon statewide assessment of mathematics. Designed for use within a response to intervention (RTI) framework, easyCBM[R] is intended to help…

easyCBM[R] is an online benchmark and progress monitoring assessment system designed for use within a response to intervention framework. Educators using easyCBM[R] are often interested in using the results to predict students' state test performance. In the following technical document, we report diagnostic efficiency statistics using a sample…

easyCBM[R] is an online benchmark and progress monitoring assessment system designed for use within a response to intervention (RTI) framework. Part of the purpose of easyCBM[R] is to help educators identify students who may be at risk for failure. Often, students deemed at-risk are those who would be predicted to not pass the state test. Previous…

California's College of the Canyons has used the four Mathematics Diagnostic Testing Project (MDTP) tests to assess students' abilities in basic and college math since spring 1989. These four reports dated June 1993, July 1993, May 1994, and June 1994 examine the predictive validity of the MDTP tests and the cut scores used to place students. The…

The National Assessment of Educational Progress (NAEP) is a congressionally mandated survey of educational achievement of American students in a variety of curriculum areas and of changes in that achievement over time. The National Assessment Governing Board (NAGB) has established new standards for reporting the results that determined three…

In 1992, a study was conducted at Golden West College (California) to determine the predictive validity of the Math Diagnostic Testing Project (MDTP) tests. A total of 1,137 students were tested in-class; 601 took the Algebra Readiness test, 376 took the Elementary Algebra test, and 160 took the Intermediate Algebra test. Two correlation…

There is a strong and consistent relationship between PSAT/NMSQT scores and AP Examination grades for nearly all courses--higher scores on the PSAT/NMSQT indicate a higher probability of success on AP Examinations. PSAT/NMSQT verbal or mathematics scores are often more highly related to AP Examination grades than overall high school GPA, number of…

This study examines the relative utility and predictive validity of the SAT I and SAT II for various subgroups in both California and the nation. The effect of eliminating the SAT I on the test impact and on the over- and under-prediction of various gender and racial/ethnic subgroups is examined. Two statistical adjustments and tables are appended.
