Project TALENT, the Equality of Educational Opportunity Survey, and the Base-Year Survey of the National Longitudinal Study tested national probability samples of American high school seniors in 1960, 1965, and 1972. This study is concerned with the feasibility of using these data for studying trends in educational attainment. Three separate…

The increasing use of educational performance or outcome measurements for a range of policy purposes points to new procedures for adjusting data for population composition. The purposes include: program formulation, budget resource allocation, grant-in-aid designs, performance incentive payments, consumer information for school selection, and…

The Anchor Test Study provides a method for translating a pupil's score on any one of eight widely used standardized reading tests for Grades 4, 5, and 6 to a corresponding score on any of the other seven tests, as well as furnishing new nationally representative norms for each of the eight tests. In addition, the Study presents new estimates of…

A Monte Carlo study was conducted to compare the statistical bias and standard errors of non-equivalent-groups linear test equating in small samples of examinees. One thousand samples of each size (15, 25, 50, and 100) were drawn with replacement from each of five archival data files from elementary school and secondary school teacher subject area…

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…

Conference speakers reviewed and analyzed the current thinking underlying the basic concepts of test norms, reliability, and validity. Roger T. Lennon's paper called for more attention to the development of norming theory and summarized current norming practices and the establishment of a system which would permit comparable norms for tests which…

The three RMC models endorsed by the U.S. Office of Education for the evaluation of Elementary and Secondary Education Act Title I programs are based on narrowly conceived approaches to evaluation--the measurement of cognitive achievement gains. Each model requires the comparison of observed student performance with an estimate of what level of…

The Anchor Test Study (ATS) yielded equating tables for vocabulary, reading comprehension, and total reading scores for eight commonly used reading tests at the 4th, 5th, and 6th grade levels. Because of the original ATS sampling design which resulted in a nationally representative sample of school children at those grades, the equating tables…

Several issues associated with equating and interpreting reading test scores from two different measures of achievement are discussed. The discussion is based on an investigation assessing the impact of classroom functional/ability grouping on academic performance of 5,439 special educational students in elementary, middle, and high schools.

Both on-level and out-of-level tests were administered to third and fifth grade children in order to compare the scaled scores of different level tests of the same testing program and to discover whether the relationship between levels might be distorted by ceiling or floor effects. Only reading tests were used in this study. The Stanford…

Goodness of fit of raw test score data were compared, using two latent trait models: the Rasch model and the Birnbaum three-parameter logistic model. Data were taken from various achievement tests and the Scholastic Aptitude Test (Verbal). A minimum sample size of 1,000 was required, and the minimum test length was 40 items. Results indicated that…

High school and college grades are suggested to have the nature of ordinal scales rather than interval scales; hence the median is the appropriate and preferred average, rather than the mean. The use of a median grade point average has some of the major advantages of pass-fail grading. Assuming grades to be ordinal rather than interval data…

This primer is an introduction to item response theory (also called item characteristic curve theory, or latent trait theory) as it is used most commonly--for scoring multiple choice achievement or aptitude tests. Written for the testing practitioner with minimum training in statistics and psychometrics, it presents and illustrates the basic…

Concern was expressed for the possible effects of testing Elementary Secondary Education Act (ESEA) Title I students with norm-referenced tests that may be so difficult that many students will have scores in the chance range. The likelihood of such students obtaining equal scaled scores if they were tested with easier out-of-level tests was…
