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;…

WHILE ATTEMPTS HAVE BEEN MADE TO CONSTRUCT MEASURES WHICH HAVE VALIDITY FOR PREDICTING ACADEMIC SUCCESS IN COLLEGE, MOST OF THESE TESTS HAVE BEEN DEVELOPED FOR NATIONWIDE TESTING PROGRAMS AND MAY NOT BE AS COMPLETELY VALID FOR MEASURING THE APTITUDE OF MINORITY GROUP HIGH SCHOOL STUDENTS WHO HAVE RESTRICTED ENVIRONMENTAL BACKGROUNDS. TO TEST THE…

MAINTAINING FLEXIBILITY IN EDUCATIONAL PROGRAMING, NECESSARY TO MEET THE CHANGING NEEDS AND SOCIAL PROBLEMS OF THE ADULT STUDENT, CALLS FOR STAFF MEMBERS' WILLINGNESS TO ADAPT TO CHANGE. THUS, PREDICTING THE ATTITUDES OF ADULT EDUCATORS TOWARD INSTITUTIONAL CHANGE IS A SIGNIFICANT CONCERN. THIS RESEARCH TESTED THE NOTION, DRAWN FROM PSYCHOLOGICAL,…

The author presents his view that the public has not been well informed about the limitations of college entrance examinations. Several educational trends are discussed: (1) since World War II, college admissions testing has underscored the classic American tension between egalitarianism and meritocracy; (2) more students have aspired to attend…

This study investigated the value of the Advanced Placement English course in New York State secondary schools, the college performances of former Advanced Placement and Non-Advanced Placement English participants, the best predictor of accelerants' performances in the first college English course, and which predictors, when combined, stabilized…
