COUNSELORS OFTEN ADMINISTER TESTS OF QUESTIONABLE VALIDITY. IN RELIABILITY STUDIES, EVERY PRECAUTION IS TAKEN TO STABILIZE THE STIMULUS SITUATION. IN ASSESSING VALIDITY, CONCERN CENTERS ON BEHAVIOR UNDER DIFFERENT STIMULUS CONDITIONS. CRONBACH'S THEORETICAL LIMIT FOR A VALIDITY COEFFICIENT OF A TEST IS THE SQUARE ROOT OF THE RELIABILITY…

In a study of the relationship between teacher behavior and reading achievement, trained observers, using the Georgia Assessment of Teacher Effectiveness (GATE), observed 36 teachers and 820 students in grades five and six. The Iowa Tests of Basic Skills, Reading Comprehension subtest was administered and the socioeconomic status of each student…

Selection criteria at a graduate school of business were examined in a study evaluating the predictive validity of the Graduate Management Admissions Test and the Miller Analogies Test for 203 recent graduates. Implications of the correlations between test results and grade point average for admission policy are discussed. (SLD)

Replication was undertaken of a recent study conducted by Buell and Anthony which had found that recidivism and posthospital employment could be predicted by a single demographic variable, number of previous hospitalizations and employment history, respectively. Results of the replication were consistent for posthospital employment but not for…

Recently there appears to have been an increase in interest in the relative power of general ability and narrower cognitive aptitudes to predict real world performance in training programs and on the job. This area has important practical implications for personnel selection and classification, particularly for large organizations such as the…

During the academic year 1978-79 school teams implemented a newly developed early identification system in all kindergarten and grade one classes in London, Ontario schools. After analysis and revision of the system, the short-term predictive validity of the process was investigated by comparing school team identification ratings made in January…

A REVISION OF THE READABILITY GRAPH WITH DIRECTIONS FOR ITS USE AND VALIDTIY DATA ARE PRESENTED. THE USE OF THE GRAPH INVOLVES WORD SAMPLES, NUMBER OF SENTENCES, AND NUMBER OF SYLLABLES. THE LATTER TWO ARE PLOTTED ON A GRAPH TO ASCERTAIN GRADE LEVELS. THE CORRELATIONS OF THE READABILITY GRAPH WITH THE DALE-CHALL, FLESCH, AND SPACHE FORMULAS ARE…

A test was made to determine the impact of positive or negative expectations on individuals conducting formal observation of teachers in the classroom for the purpose of evaluation. Two groups of graduate students who were receiving training in classroom observation viewed a video tape of a teacher instructing her class. Group one was given the…

In the spring of 1966, a follow-up study of the original form of the ACT Student Profile Section (SPS) was conducted at 35 colleges. As a part of the larger study, this report investigates the question of how accurately the students' pre-college responses predicted their behavior and plans during the first year of college. The follow-up data were…

Using academic achievement data for 655 University students, direct validation of differential predictions based on a battery of aptitude/achievement measures selected for their differential prediction efficiency was attempted. In the cross-validation of the prediction of actual differences among five academic area GPA's, this set of differential…
