An initial study of the revised (1985) Student Descriptive Questionnaire (SDQ) of the College Board found it to be of sufficient accuracy to fulfill its intended purposes. This second phase examined the adequacy of the SDQ in terms of the predictive validity of its student academic self-report information against a criterion of first-year college…

A study was undertaken at California's Riverside Community College District to determine predictors of grades and success rates in a first-semester general chemistry course. Fall 1996 course outcomes were analyzed for two groups of students: 137 who had completed the course, successfully or not, and 178 who had dropped it. Data were also collected…

The Bean and Metzner Nontraditional Undergraduate Student Attrition Model appeared to be a good model to address community college student attrition because it takes into account the environmental variables that colleges must consider to enhance persistence. A study was conducted to determine how well the Bean and Metzner Model fit with community…

As a consequence of a validation study based on over 200 skilled technicians employed in engine manufacturing, seven aptitude tests were administered to 50 applicants in June 1982. This report presents correlations between test scores and three criteria (math grades, job performance ratings, and a composite) for the 26 people who entered the…

Although frequently attacked as invalid, demeaning, biased, illegal, and irrelevant, preemployment testing procedures appear to be increasing in popularity. Many prominent companies and organizations are making extensive use of tests. Part of the resurgence of testing is attributable to clearer definitions of acceptable practice. Legal precedents…

In forecasting its fall credit headcounts, the Office of Institutional Research and Analysis at Prince George's Community College (PGCC) utilizes the Component Yield Method (CYM), an enrollment projection model developed by the college's planning analyst in the early 1980's. By disaggregating enrolled students into multiple groups, each with an…

The National Teacher Examination (NTE) was given to a sample of 64 new trades and industrial (T&I) teachers attending 6-week workshops in Maryland during three summers. Each summer 18 to 25 teachers took the three tests in the Core Battery of the NTE, as well as a selection of other tests. The project sought to determine the pass-fail ratio of…

Three research studies conducted at Thai universities involving language testing and courses in General English and English for Academic Purposes (EAP) are discussed. The first study examined the predictive validity of different types of language tests on academic achievement in General English and EAP courses. It found that the test format, as…

From the fall of 1981 through June 1984, more than 850 disabled examinees took special administration of the Graduate Record Examinations (GRE). Grade point averages were obtained on 278 disabled students; 236 had enough complete data to be included in the study. Disabled students earned lower mean GRE scores than their nonhandicapped counterparts…

The first purpose of this study was to examine the relationships between changes made during the development of written instruction and the effectiveness of the materials when presented to students. For this purpose, the Written Instruction Stylistic Evaluation was used to assess the comprehensibility of passages before administration of the…

Tinto's conceptual schema of college dropout forms the theoretical framework for the development of a model of university student dropout intention. This study validated Tinto's model in two different departments within a single university. Analyses were conducted on a sample of 684 college freshmen in the Education and Economics Department. A…

A study was conducted at Miami-Dade Community College (MDCC) to provide data on the relationship of cumulative grade point average (GPA) and College-Level Academic Skills Test (CLAST) performance. Because Florida community college students must be eligible for graduation in order to take the CLAST, the study focused mainly on MDCC students with…

A visual display is introduced that enables one to compare the predictive validities of all possible non-negatively weighted sums of two predictors. This two-predictor validity curve assesses the level of predictability of a criterion from composites of two predictors. Derivations are presented for the general case. For illustrative purposes, the…

The validity of the Communication Skills and General Knowledge portions of the NTE (National Teacher Examination) Core Battery as predictors of student performance was examined, including scores on the test of professional knowledge required for certification in teacher education programs. This predictive validity was compared to that of the…

This report addresses the problem of sample size in developing prediction equations for college freshman grade averages under the American College Testing (ACT) Assessment Program. For the ACT Assessment, the prediction weights are estimated by standard least squares procedures. Because prediction weights are estimated regression coefficients…
