Functioning-level testing has been proposed as an alternative to grade-level testing for the evaluation of compensatory educational programs in which students score well below their own grade level. Data from two studies, however, suggest an adverse impact on program evaluation from the adoption of functioning-level testing. Two compensatory…

Empirical reliabilities of scores based on item-pattern scoring, using 3-parameter item-response theory and number-correct scoring, were compared within each of 5 score metrics for at least 900 elementary school students for 5 content areas. Average increases in reliability were produced by item-pattern scoring. (SLD)

A test of mental arithmetic skills was developed and normed for children in grades one to six. Statistical techniques were used to predict the probability correct for each item and to rank order the items. Students in a given grade took only one level of the test and inferences were made of their performance on those tests which they did not take.…

Retention practices are poorly documented yet the most comprehensive research on retention (Holmes and Mathews) shows that children who repeat a grade make less progress than similar children who are promoted. Explores the contradiction existing between school reform policy and actual retention practice. (MD)

The developer of the Comprehensive Tests of Basic Skills scaling responds to Hoover's attacks on Thurstone and item response theory scales (TM 510 173). While agreeing that grade equivalent (GE) scores are presently the most appropriate developmental score for reporting elementary grade achievement tests, limitations and inconsistencies in the GE…

Statistical methods and test writing for reading comprehension have been based on the assumption that certain reading tasks or levels are appropriate at one age level that would be too difficult at another. A clear-cut determination of grade levels for reading materials has, however, not been defined. Grade and age equivalent scores on silent…

Grade equivalent (GE) scores for elementary school achievement tests are defended in response to efforts to ban their use. Equal interval developmental scoring methods for the Sequential Tests of Educational Progress and the Comprehensive Tests of Basic Skills are criticized. (BS)

A comprehensive assessment was made of the status of elementary education in Missouri in reading, mathematics, language, and study skills. The Comprehensive Tests of Basic Skills (CTBS) and the Short Form Test of Academic Aptitude (SFTAA) were administered to a sample of Missouri fourth and sixth graders. For each curricular area, Missouri…

The relative magnitudes of R-squared values computed through multiple regression models using grade equivalent scores, raw scores, standard scores, and percentiles as both predictor and criterion variables are compared. Grade equivalents and standard scores produced the highest R-squared values. (Author/JKS)

This guide explains the concept of out-of-level testing and suggests a formula for estimating the occurrence of floor effects and ceiling effects, within the context of models for evaluating Elementary Secondary Education Act (ESEA) Title I programs. An analogy explains floor and ceiling effects as if test items are stored in different levels in a…

The author addresses issues raised by Burket (TM 510 174) about the Iowa Test of Basic Skills scaling procedures. Further reasons for his criticism of Thurstone scale scores and item response theory scale scores for elementary school achievement tests are given. (BS)

School unit achievement gains computed by six different methods are compared. The data include total reading scores from the Metropolitan Achievement Test administered to Title I students in 32 elementary schools. The achievement gains were computed in standard scores, grade equivalents, percentile ranks, residual scores based on individual scores…

The use of standardized achievement tests as the primary criterion measures in the evaluation of basic skills programs has been criticized. In a comparative study of three types of tests, this article examines the major issue behind this criticism. (Author/JAZ)

To eliminate maturation as a factor in the pretest-posttest design, pretest scores can be converted to anticipate posttest scores using grade equivalent scores from standardized tests. This conversion, known as historical regression, assumes that without specific intervention, growth will continue at the rate (grade equivalents per year of…

While most school districts believe they understand grade equivalent scores, teachers, parents, and measurement specialists frequently misinterpret this apparently simple statistical expression. Echternacht's article describes the construction, application, and interpretation of grade equivalent scores from the test publisher's perspective.…
