Diagnostic judgments are often based on the comparison of two measures in order to judge whether the individual shows a genuine discrepancy in the traits or characteristics that the two measures represent. Until a perfect psychometric battery comes along, psychometricians can offer some guidance on the level of confidence to be placed in…

Explanations of and guidelines for using the Stanford Achievement Test for Hearing Impaired (SAT-HI) children are given. Types of scores from the test (raw scores, grade equivalent scores, scaled scores, and percentile rankings) are described. Limitations on test interpretations are suggested as well as reminders on using achievement test scores…

The use of Stanford Achievement Tests (SATs) with hearing impaired students is considered. Background of the test is given, and the SAT-HI (SAT for the Hearing Impaired) is discussed in terms of its content, item wording, and norms. Among six specific recommendations made are to use the SAT-HI because it minimizes floor and ceiling effects,…

The factorial validity of the Stanford Achievement Test (SAT) was investigated with a sample of first graders (n=393). Although eight areas are proposed from the SAT, this analysis produced only one general factor. Results suggest limiting SAT interpretation for first graders to a total score approach. (Author/BS)

As a preliminary step in customizing the Stanford Achievement Test, a study was made to compare the test items at each level with the curriculum objectives of a Florida school district, classifying them as either matching, above or below grade level, or unmatching. Results are shown in table form. (TE)

The sampling of test items found within the Science portion of selected standardized achievement test batteries is examined. The lack of sensitivity of such items to the curriculum changes often attempted in Earth Science is demonstrated. The following five standardized achievement test batteries commonly administered to pupils in grades 7-9 were…

Describes procedure for combining Stanford Achievement Test items with local supplementary items to measure individual and aggregate student performance in mathematics. Two reports are generated from the test results: a diagnostic report of student mastery of each objective and an overall score. (TE)

An analysis of SAT-9 scores since passage of Proposition 227 indicates that scores increased for all students, not just for English-learning students; scores increased for most districts regardless of the programs implemented; it was not possible to isolate the impact of Proposition 227; and SAT-9 is not an appropriate measure for assessing…

This study provides data on norming and performance standards on the Stanford Achievement Test, 9th Edition, for both hearing and deaf students. It graphically analyzes these data in the context of interpreting individual test scores, examining achievement of groups of students, and specifically, interpreting test scores of high achieving deaf and…

The purposes of this study were to compare student, school, and group average distributions of two standardized tests, the Iowa Tests of Basic Skills (ITBS) and Stanford 7 Plus Achievement Test, and examine the American College Testing Programs college entrance examinations (Grades 11-12). In addition to the student-school norm comparisons, ratios…

Recent test results reveal that the test score decline has ended, but the legacy of this highly publicized educational episode continues. One widespread interpretation of the decline and recovery is that permissiveness and a collapse of standards in the late 1960s led to the decline and that a return to the basics and to tougher standards caused…

This study attempts to detect the presence of either of 2 different categories of large-scale bias in 4 widely used mathematics achievement tests: induced bias and norming bias. Subjects were 407 eighth graders. (IAH)

How two students with the same number-correct score, calculated by dramatically different patterns of responses, can achieve the same ability estimate is demonstrated. The present study investigated the incidence of person misfit to the model in a nationally standardized test of achievement devised using the Rasch item response theory model. It…

Proposes that objective-referenced tests replace norm-referenced tests as a vehicle for program evaluation. Describes a methodology, based on latent trait theory, for joining norm-referenced and objective-referenced testing in a customized testing program. (TE)

This report summarizes the results of the 1984 and 1985 administrations of the following tests in Hawaii: (1) the grade 8 Stanford Achievement Test (SAT), Advanced Level, 6th edition, of the Vocabulary, Reading Comprehension, Spelling, and Language Subtests; and (2) the grade 10 Stanford Test of Academic Skills (TASK), Level 1, 6th edition of the…
