An equating procedure for a testing program with evolving distribution of examinee profiles is developed. No anchor is available because the original scoring scheme was based on expert judgment of the item difficulties. Pairs of examinees from two administrations are formed by matching on coarsened propensity scores derived from a set of…

This manual was written to provide technical information regarding the General Educational Development (GED®) test as evidence that the GED® test is technically sound. Throughout this manual, documentation is provided regarding the development of the GED® test and data collection activities, as well as evidence of reliability and validity. This…

This technical report provides detailed information regarding the technical, statistical, and measurement attributes of the New York State Testing Program (NYSTP) for the Grades 3-8 Common Core English Language Arts (ELA) and Mathematics 2016 Operational Tests. This report includes information about test content and test development, item (i.e.,…

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…

This technical report provides detailed information regarding the technical, statistical, and measurement attributes of the New York State Testing Program (NYSTP) for the Grades 3-8 Common Core English Language Arts (ELA) and Mathematics 2015 Operational Tests. This report includes information about test content and test development, item (i.e.,…

This technical report provides detailed information regarding the technical, statistical, and measurement attributes of the New York State Testing Program (NYSTP) for the Grades 3-8 Common Core English Language Arts (ELA) and Mathematics 2014 Operational Tests. This report includes information about test content and test development, item (i.e.,…

An attempt was made to evaluate the standard error of equating (at the mean of the scores) in an ongoing testing program. The interest in estimating the empirical standard error of equating is occasioned by some discomfort with the error normally reported for test scores. Data used for this evaluation came from the Admissions Testing Program of…

Test developers continue to struggle with the technical and logistical problems inherent in assessing achievement across different languages. Many testing programs offer separate language versions of a test to evaluate the achievement of examinees in different language groups. However, comparison of individuals who took different language versions…

The research leading to the decisions to revise the Graduate Record Examination Aptitude Test (GRE) (beginning in October 1981) is reviewed. The issues discussed include the format of the test (the timing of each section and the number of sections, the content of the sections--especially the analytical section), the scoring procedure for the GRE,…

Effects of passage and item-scrambling on equipercentile and item-response theory equating were investigated using 2 scrambled versions of the American College Testing Program Assessment for approximately 25,000 examinees. Results indicate that using a base-form conversion table with a scrambled form affects the individual examinee level. (SLD)

Although few question the positive impacts alternative forms of assessment can have on instruction, concerns about the psychometric quality of data obtained from such assessments are taking their toll. Scoring issues are at the heart of many of these concerns. This paper addresses the causes of these concerns: misinformation about psychometric…

Statistical equating of scores from direct writing assessments is performed in Maryland to hold the difficulty of passing the Maryland Writing Test (MWT) equivalent from year to year and to allow a demonstration of growth in student writing achievement over the years. Passage of the test is a high school graduation requirement. Prior to…

This paper summarizes an investigation of applications and issues in free response (FR) testing during 1989. It draws on ideas from the results of the National Educational Longitudinal Study 1988 (NELS:88) field test, a seminar series at the Educational Testing Service (ETS), working papers prepared for several FR testing applications, and…

The current New Jersey high school graduation law requires that students pass a ninth grade test in reading, writing, and mathematics. Equating the writing test from year to year to be sure that passing scores remain identical, regardless of the test form administered, requires developing a scoring technique. A research study was developed based…

This manual contains preliminary information, largely of a technical nature, about the enhanced American College Testing (ACT) Program introduced in October 1989. It focuses primarily on the tests of educational development, the component of the program that has been substantially revised. Although one-third of the ACT Interest Inventory Items has…
