This study determined the validity of vocational interest scores for persons with high, medium, and low levels of experience appropriate to their predominant interests. The experiences and interests of a national sample of 1,380 young adults were assessed concurrently with scales paralleling Holland's types. The degree of congruence between…

From l979 to l985, data were gathered from approximately 600 students in 24 Dutch elementary schools to determine changes occurring in the interrelationships among the reading skill components of decoding, reading comprehension, and spelling ability. Information for each student was obtained from reading performance test scores recorded at the end…

This study examined how well the scores from the revised National Teacher Examinations (NTE), the American College Test (ACT), cumulative grade point average, personal characteristics, and certification level can predict actual classroom performance, as measured by three instruments from the Teacher Performance Assessment Instruments (TPAI).…

The York Region Board of Education in Ontario, Canada, screens students for giftedness in grade 3. This report analyzes data produced in the 1986-87 screening procedure, involving approximately 3,400 students. The report begins with a review of procedural changes that were designed to make the screening more effective and efficient than earlier…

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:…
