The release of School Grades by the State of Florida in the late summer of 2010 created quite a stir. Over 500 elementary schools all over the state dropped at least one grade level. Among those schools that experienced drops, the Reading Gains and Mathematics Gains components seemed especially low. Some of the historically best performing schools…

This Digest introduces the advantages and disadvantages of three commonly used methods of reporting test score changes: (1) change in percentile rank; (2) scale or raw score change; and (3) percent change. The change in percentile rank method focuses on the increase or decrease of the mean percentile ranking for a group of students. This method…

Attempted to improve the measurement quality of a complex performance assessment through principled assessment design using the example of the National Board for Professional Teaching Standards Early Childhood/Generalist examination. All indexes examined improved after revisions were made. Results show the importance of attention to assessment…

An earlier Digest described the shortcomings of three methods commonly used to summarize changes in test scores. This Digest describes two less commonly used approaches for examining changes in test scores, those of Standardized Growth Estimates and Effect Sizes. Aspects of these two approaches are combined and applied to the Iowa Test of Basic…

Studied modeling individual latent growth curves of older adults on measures of fluid intelligence by fitting second-order polynomial curves reflecting initial test performance improvement followed by relative stability/drop to the recorded scores of each of 248 subjects. Results suggest substantial plasticity in fluid intelligence of older…

The effects of student coaching in preparation for the College Board Scholastic Aptitude Test (SAT) on the predictive validity of this test for freshman year performance were studied using data on 1985 freshman year students from four colleges. After the validity of the SAT was estimated for each school, a given proportion of students was picked,…

Data from the College Board Validity Study Service show that the average multiple correlation of the Scholastic Aptitude Test (SAT) with college grades peaked in 1974 and then tended to decline. Data from other sources also estimate a small average decline from 1974 to 1985. This study documented changes in the SAT and related these changes to…

Scholastic Aptitude Test (SAT) scores, student-reported high school grades, and scores for four other Admissions Testing Program tests were correlated with freshman grade point average for 299,794 students at 198 colleges from the enrolling classes of 1978, 1981, and 1985. The purpose of the study was to determine whether observed changes in…

This study analyzed data from a survey conducted in 1987. The sample consisted of 2,136 examinees who took the Graduate Record Examination (GRE) during 1986-87. The purpose was to determine how well the intended field-of-study item in the GRE background questionnaire can be relied on as an indicator of what examinees will actually study in…

Changes in verbal, spatial, and reasoning intelligence among Swedish 13-year olds were studied from 1960 to 1990. Rising verbal scores until 1980 have been followed by a decline to essentially the 1960 level. Spatial and reasoning results have risen continuously. Gender and social class differences are discussed. (SLD)

As part of a continuing evaluation of the Swedish school system, changes in intelligence test scores from 1960 to 1995 were studied in relation to cohort, gender, and socioeconomic background. Changes in verbal, spatial, and reasoning ability were studied by comparing results on identical tests given to representative samples of Swedish…

Effects of the policy of mandated busing for integration on overall achievement test scores of African-American children were studied with 434 elementary school students in Norfolk (Virginia). Achievement test scores declined after the elimination of mandated busing. School characteristics explained 9% of the variance in scores for all students.…
