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…

A study was conducted at St. Louis Community College to validate the Nelson-Denny Reading Test (NDRT), Form C, as an instrument for student placement, to empirically establish a cutoff score for a mandatory reading improvement program, and to provide more complete and meaningful feedback to students about their reading test results. The study…

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…

In Fall 1994, the San Diego Community College District (SDCCD), in California, conducted a study to determine the validity of the Mathematics Diagnostic Testing Project (MDTP) placement test. The MDTP provides tests at four levels (i.e., algebra readiness, elementary algebra, intermediate algebra, and pre-calculus) and is used in the District for…

This report describes a large scale research effort to validate and improve the Armed Services Vocational Aptitude Battery (ASVAB) aptitude area (AA) composites now used by the Army to select and classify enlisted personnel. Data were collected from existing Army sources on over 60,000 soldiers and over 60 Military Occupational Specialties (MOS).…

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…

The purpose of the NMSBA technical report is to provide users and other interested parties with a general overview of and technical characteristics of the 2007 NMSBA. The 2007 technical report contains the following information: (1) Test development; (2) Scoring procedures; (3) Summary of student performance; (4) Statistical analyses of item and…

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…

Each year, Pennsylvania students participate in testing as part of the Pennsylvania assessment program. Students in grades 5, 8, and 11 take tests in reading and math while those in grades 6, 9 and 11 are assessed in writing. These tests serve as an important measure of student achievement for the state's accountability system. Results from these…

Each year, South Carolina students participate in testing as part of the South Carolina assessment program. Students in grades 3 through 8 take the Palmetto Achievement Challenge Tests (PACT) in English/Language Arts and Mathematics. Students in grade 10 take the High School Assessment Program (HSAP) in English/Language Arts and mathematics. These…

This study investigated the relationship between the scales used for the ISTEP+ assessments and the RIT scales used to report performance on Northwest Evaluation Association tests. The RIT scale was developed using Rasch scaling methodologies. RIT-based tests are used to inform a variety of educational decisions at the district, school, and…

As part of an effort to statistically validate the placement tests used in California's San Diego Community College District (SDCCD) a study was undertaken to review the criteria- and content-related validity of the Assessment and Placement Services (APS) reading and writing tests. Evidence of criteria and content validity was gathered from…
