The first of a series of quizzes on types of derived scores concerns interpreting grade-equivalent (GE) scores. The true-false items require a response about whether the stated interpretation of the GE score is sound. An answer key explains specific scoring methods. (CM)

The cautions needed for correctly interpreting grade equivalent scores are presented simply, for persons who are not statisticians. Four potential limitations of grade equivalent scores are summarized. (1) Comparisons across grades are of little value when the subject content is not the same; for example, sixth grade American history is not…

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…

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…

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)

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 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)

A STUDY OF FIVE DIFFERENT ESSAY EVALUATION PROCEDURES WAS CONDUCTED TO DETERMINE THE INTRARELIABILITY OF EACH AND TO USE THESE RELIABILITY SCORES AS A BASIS FOR COMPARING THE FIVE PROCEDURES. TEN THEMES WERE ASSIGNED TO FIVE RATING GROUPS, EACH USING A DIFFERENT EVALUATION PROCEDURE--(1) THE CALIFORNIA ESSAY SCALE, (2) THE CLEVELAND COMPOSITION…

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.…

For Title I evaluations, it may be appropriate to test out-of-level; that is, to override publisher's recommendations concerning the difficulty, length, and content appropriate for a particular grade. It is seldom necessary, however, to move more than one grade down. If the mean is substantially higher than the median, then some pupils will have…

An experiment investigated the extent to which the results of out-of-level testing may be biased because the child given an out of level test may have had a significantly different curriculum than the children given in-level tests. Item analysis data suggested this was unlikely. (CTM)

Out of level testing is defined and reasons for administering out of level tests, especially in compensatory education programs are explained: (1) to achieve optimum test reliability; (2) to test student achievement--provided out of level test scores are interpreted in terms of the appropriate in-level population; (3) to avoid carelessness and…

The Portland Board of Education had requested that the Oregon Central Evaluation Department provide student achievement data so as to allow comparisons with other school districts by reporting national grade level equivalent (GLE) scores on standardized tests of reading and mathematics for grades 4 and 8. For years, the position of most research…

This study was mounted to assess the validity of standard score transformations of raw test scores and test bias on the 1970 edition of the Metropolitan Achievement Test Battery, in the context of a controversial federally funded compensatory education program, the Educational Voucher Demonstration (EVD). On an individual level the validity of the…
