A method for calculating "standardized" grade equivalents for learning disabled students is criticized because it recreates some problems of the original mental age concept and has little to offer teachers or diagnostic personnel. (Author/CL)

A procedure for checking the score equivalence of nearly identical editions of a test is described and illustrated with Scholastic Aptitude Test data. The procedure uses the standard error of equating and uses graphical representation of score conversion deviations from the identity function in standard error units. (SLD)

Limitations of grade and age equivalent scores in the educational assessment of handicapped students include unequal variance across content areas, grade and age groups, and encouragement of comparison with inappropriate groups. The author recommends the use of expanded scale scores. (Author/CL)

Two principles and one verbal technique provide a sound basis for communicating to students and their parents the information obtained from testing: (1) parents have the right to know whatever the school knows about the abilities, performance and problems of their children; (2) the school has the obligation to see that it communicated…

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)

Guidelines for explaining standardized test results to parents of students are provided. More specifically, the guidelines cover rationales for testing, the various types of scores and their meanings, and means of interpreting scores. Scores covered include stanine scores, percentile scores, and grade-level equivalent scores. The importance to…

The study examined the hypothesis that different evaluative interpretations of studies of special education effectiveness may be a function of the manner in which data are summarized and reported. Four metrics are compared including raw score, grade-equivalent score, z-score, and discrepancy index. Criteria for selecting metrics for program…

The advantages and disadvantages of grade equivalent (GE) scores are explored, including appropriate uses for GE type scores and how to bring current GE scales closer to the type of information educators appear to desire. Although GE scores are not an equal interval scale, not comparable across school subjects, and do not indicate the grade level…

Organized as a question-and-answer booklet, this parents' guide explains scores on standardized reading achievement tests. Examples illustrate the meaning of certain grade equivalent scores. The grade equivalent method is described as a poor way to report scores; raw scores, percentiles, and stanine ranges are discussed as alternatives. The…

The single most important output of any school is probably the magnitude of its students' growth in academic achievement. A variety of standardized tests has been developed to measure aspects of this achievement; however, only recently have administrators attempted to use such tests to help review and make decisions about educational programs.…

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)

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…

This document contains 49 pages of tables presenting data ranking schools' reading achievement in New York City. Scores are from the Degrees of Reading Power test administered in grades 3 to 10 in 1986. This report complies with the New York City Decentralization Law's requirement that each school be ranked by the percentage of pupils reading at…

In certain situations, grade equivalent scores are the most appropriate statistic available for reporting achievement test data. It is noted that testing practitioners have found that raw scores, normal curve equivalents, stanines, and standard scores are very useful. However, it is best to convert to either grade equivalents or percentiles before…

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.…
