In this study, I investigated 2 procedures intended to create test-taker groups of equal ability by poststratifying on a composite variable created from demographic information. In one procedure, the stratifying variable was the composite variable that best predicted the test score. In the other procedure, the stratifying variable was the…

This study examined the extent to which log-linear smoothing could improve the accuracy of differential item functioning (DIF) estimates in small samples of examinees. Examinee responses from a certification test were analyzed using White examinees in the reference group and African American examinees in the focal group. Using a simulation…

This research examined the relation between test-retest changes on scholastic aptitude tests and g-loaded cognitive measures (viz., college grade-point average, Wonderlic Personnel Test, and word recall). University students who had twice taken a scholastic aptitude test (viz., Scholastic Assessment Test or American College Testing Program…

This report contains the results from the first administration of the fourth and sixth grade science and social studies portions of the Delaware Student Testing Program (DSTP). As such, they are an important part of the state's efforts to educate all students to a higher level. Science and social studies data for grades 4 and 6 are summarized…

The statistical parallelism of a pair of tests equated by the P-value method was investigated, as well as the relationship between their raw scores and scores transformed by linear equating. Data were obtained from eight sections of the 1980 New Jersey Minimum Basic Skills Program; specifically, the reading and mathematics tests for each of grades…

This report contains summaries of the results from the third administration of the fourth and sixth grade science and social studies portions of the Delaware Student Testing Program (DSTP). These results are part of a long-term effort to gather data on the educational progress of Delaware students and to use the data to inform decisions about…

The correlations of each of the 22 tests in the Johnson O'Connor Research Foundation battery with all other tests in the battery are listed. Four fairly large samples are used, each including cases of one sex and a narrow age range. These cases come from a file of 3,555 examinees tested between June 1981 and the fall of 1982. The purpose of…

A procedure is described for estimating the reliability and conditional standard errors of measurement of scale scores incorporating the discrete transformation of raw scores to scale scores. The method is illustrated using a strong true score model, and practical applications are described. (SLD)

The results from the third administration of the 8th and 11th grade science and social studies portions of the Delaware Student Testing Program (DSTP) represent an important step in Delawares efforts to educate all students to a higher level. Science and social studies data for grades 8 and 11 are summarized here, and the results for grades 4 and…

This report contains the results from the first administration of the 8th and 11th grade science and social studies portions of the Delaware Student Testing Program (DSTP). As such, they are an important part of the state's efforts to educate all students to a higher level. Science and social studies data for grades 8 and 11 are summarized here;…

Issues related to linking tests with constructed response items were explored, specifically by comparing single-group and anchor-test designs to link raw scores from alternate forms of performance-based student assessments in the context of Delaware's assessment program using performance-based assessment. This study explored use of the two test…

Results of the Alberta, Canada Grade 12 Diploma Examinations Program are presented for the January 1985 test administration. All twelfth grade students are required to pass at least one of these tests in order to receive a high school diploma. Some students also receive course credit by passing the appropriate examination. Examinations are…

The administrators' and teachers' manual for the New York State Preliminary Competency Test in Reading provides information on the student population to be tested; the degrees of reading power (DRP) methodology to measure students' reading comprehension; the test content; and the state reference point, a cutoff score expressed in terms of…

Florida's Statewide Assessment Program of the State Department of Education has been involved in a major effort to develop adequate strategies for releasing and publishing assessment scores for schools. One dimension of this effort has been the development of predicted or "adjusted" scores. These scores compare a school to other similar…

The Statewide Assessment Program of the Florida State Department of Education is responsible for measuring student achievement and disseminating the assessment results. One dimension of this effort has been the development of predicted or adjusted school scores. These scores are based on several factors which are related to achievement. Among…
