Administered the Slosson Intelligence Test (SIT) to 92 preschool children. Administered the Stanford-Binet Intelligence Scale to a sample of the group, and the results were compared to the results from the SIT. Results indicated the SIT overestimated the performance of average preschool children. (Author)

Addresses issues faced by institutions attempting to design school profiles to meet accountability standards. Reports of high-stakes test results can be skewed by choice of statistic type (percent of students passing versus mean scores), sample bias, geographical transients, and omission errors. Administrators must look beyond "common…

Many testing programs include a section of optional questions in addition to mandatory parts of a test. These optional parts of a test are not often truly parallel to one another, and groups of examinees selecting each optional test section are not equivalent to one another. This paper provides a general method based on missing-data methods for…

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

A popular method of analyzing test items for differential item functioning (DIF) is to compute a statistic that conditions samples of examinees from different populations on an estimate of ability. This conditioning or matching by ability is intended to produce an appropriate statistic that is sensitive to true differences in item functioning,…

The relationship between student scores on standardized achievement tests taken in the eighth grade and the Ohio Ninth Grade Proficiency Test (ONGPT) was studied to determine whether standardized achievement test cut-off scores can be used in place of the ONGPT. Students enrolled in the eighth grade in an urban school district in the spring of…

Concern was expressed for the possible effects of testing Elementary Secondary Education Act (ESEA) Title I students with norm-referenced tests that may be so difficult that many students will have scores in the chance range. The likelihood of such students obtaining equal scaled scores if they were tested with easier out-of-level tests was…

It is often proposed that high schools are partly to blame for the decline in achievement test scores. Critics of current practices in education cite the decline in Scholastic Aptitude Test (SAT) score averages that has occurred each year since 1963 as evidence. The College Entrance Examination Board Advisory Panel on SAT Score Decline has…

A group of highly regarded schools in affluent suburban areas was divided into two groups: those judged to have a traditional orientation and those judged to have a more experimental orientation, in terms of course and program structure. A review of the mean Scholastic Aptitude Test (SAT) from the 1966, 1969, 1973, and 1976 graduating classes from…

The Scholastic Aptitude Test (SAT) scores of the 1960 to 1974 valedictorians and salutatorians from a sample of public, experimental, and private schools were studied. The experimental schools were specifically chosen for demographic stability. The comparison schools were also selected for stability, but by less stringent criteria. For the…
