Whether adjustments to differential prediction observed among sex, racial/ethnic, or age subgroups in a college-level freshman class could be used to improve grade prediction accuracy for these subgroups in future freshman classes was studied. This study is based on the American College Testing program test scores, high school grades, and college…

The management development program (MDP) at the University of Tulsa provides an opportunity for identification and development of managerial skills among administrators in the elementary and secondary schools of northeastern Oklahoma. The validity of assessment center exercises for predicting performance as a school principal was examined by a…

A study was conducted (1) to obtain an estimate of the amount of error in prediction that occurs when static measures are used to interpret work-sample performance; (2) to identify a number of dynamic performance measures that reflect learning that might occur on the task; and (3) to compare the predictive accuracy of those measures to that of…

This study investigated (1) selected academic, personality, and attitude characteristics of the Wright State University School of Medicine (WSUSOM) class of 1984 and (2) the relationships between first-year grades and various personality, attitude, and premedical academic measures. In September 1980, first-year medical students (n-99), class of…

Heckman's correction for regression in selected samples for predictive validity studies was applied to a large data file on 7,984 law school applicants. Data included ethnic group, sex, socioeconomic status, undergraduate degree, school, scores on the Law School Admission Test (LSAT), writing ability, undergraduate grade point average, and age.…

Classical statistical methods and the small enrollments in graduate departments have constrained the Graduate Record Examinations (GRE) Validity Study Service to providing only validities for single predictors. Estimates of the validity of two or more predictors, used jointly, are considered too unreliable because the corresponding prediction…

This report summarizes selected information from American College Testing (ACT) Program records (1978-79 through 1982-83) for five groups of ACT Assessment examinees: (1) examinees who indicated that they did not have a disability that might require special services from the college they planned to attend (these examinees tested on national test…

Previous research has studied the effects of different methods of item option weighting on the reliability and concurrent and predictive validity of achievement tests. Increases in reliability are generally found, but with mixed results for validity. Several methods of producing option weights, (i.e., Guttman internal and external weights and…

This study seeks evidence for the validity of the concept of egocentrism in children. Three standard egocentrism tests are intercorrelated to determine the degree to which they appear to be measuring a single construct (convergent validity); whether the three tasks intercorrelate more than they do with a theoretically unrelated task (discriminant…

A study explored the relation between Piagetian conservation tasks, IQ scores, and reading test scores. A series of 16 items involving conservation tasks for area, length, weight, and volume were presented to 516 students in grades four through nine. The scores on these conservation items were correlated with students' scores on achievement and IQ…

A review of literature by reading authorities identified seven criteria necessary for meaningful research about reading readiness tests. These criteria were then used in analysis of 15 research studies dealing with the "Metropolitan Readiness Test" and first grade reading achievement. Five major findings resulted from this analysis:…

This longitudinal study examined the relationship of the physical-neurological conditions of infants at one minute after birth to mental and motor development at prekindergarten and kindergarten levels. Subjects were 44 children, 16 males and 28 females, born in 1970 in the same hospital. Neonatal physical status one minute after birth was…

Thirty-four research reports and summaries of projects studying law school admission and the Law School Admission Test (LSAT) are presented. These research projects were supported by the Law School Admission Council between 1970 and 1974. A subject index and an author index for volume I, covering 1949-1969, and for this volume are also provided.…

This study investigated the predictive power of four indices of cognitive style, the intercorrelations of cognitive style with selected cognitive and affective variables, and the test-retest reliability of the Matching Familiar Figures (MFF) test. The social, emotional, and cognitive development of 38 kindergarten children was assessed by their…

Thirteen of the 41 classroom observation dimensions derived from Medley's review of teacher effectiveness reports were scored on the Georgia Assessment of Teacher Effectiveness. Subjects were 53 fifth and sixth grade teachers in language arts and mathematics. The dimensions were: large group instruction; group size without adult supervision;…
