The reliability of an assessment is defined as the extent to which candidates' results would remain stable if the entire assessment exercise was repeated. Whilst numerous studies have evaluated the reliability of written examinations, relatively little has been done to quantify the reliability of internal teacher assessment within schools. This is…

Building on Shulruf, Hattie and Tumen (2008), this work examines the capacity of various National Certificate in Educational Achievement (NCEA)-derived models to predict first-year performance in Biological Sciences at a New Zealand university. We compared three models: (1) the "best-80" indicator as used by several New Zealand…

The Texas Projection Measure (TPM) has grown out of the state's need to meet the requirements of No Child Left Behind (NCLB). An examination of the state's method of predicting 8th grade mathematics scores reveals that several factors have been ignored in the process of developing the model, including assumptions in its underlying statistical…

Examined the construct validity of scores on the Psychological Empowerment Scale of G. Spreitzer (1995). Confirmatory factor analysis of data from 160 nurses supported Spreitzer's four empowerment dimensions, and these findings were cross-validated with a subset from the same sample. Results also support the predictive validity of the scale.…

The study was conducted to provide formulae by which College-Level Examination Program (CLEP) General Examination scores may be predicted from scores earned on the American College Test (ACT) Assessment. Five basic areas of liberal arts achievement are measured by the CLEP General Examinations: English Composition, Humanities, Mathematics, Natural…

One purpose of this study was to compare the incremental effectiveness over high school grade point average (GPA) alone of the American College Testing Program (ACT) assessment, the Scholastic Aptitude Test (SAT), and the California Achievement Tests (CAT) in predicting college freshman GPA. A second purpose was to look at the relative…

Using a national sample of recent medical school graduates (n=12,213), a study of predictive validity of the National Board of Medical Examiners test parts I and II found strong correlations between performance on those parts and part III, supporting the test's use, at least in part, for selection of residency applicants.

Several advantages to the use of factor scores as independent variables in a multiple regression equation were found. To help select the most desirable type of factor score on which to calculate a regression equation, computer-based Monte Carlo methods were used to compare the predictive accuracy upon replication of regression of five…

Evidence indicates that college grades have increased on the average and that the college-bound population has decreased in traditional kinds of academic skills, based on observed declines on the Scholastic Aptitude Test (SAT) and the American College Test (ACT). But the relationship between these traditional skills and grades appears not to have…

Previous research has shown that students often overestimate their performance levels on course examinations. A model of motivation was applied to an individual's predictions and postdictions of his/her own performance levels in course examinations to obtain actual predictions and postdictions for 111 college students over a period of three…

The predictive validity of the new Medical College Admission Test (MCAT) was examined; the validity coefficients were compared to those obtained from previous versions of the MCAT and from performance data gathered early in a first-year basic science program. Data were collected from about 400 medical students, including: (1) MCAT…

The purpose of this study was to test the predictive efficiency of the Graduate Record Examination Analytical (GRE-A) score when used in combination with other predictors for doctoral candidacy decisions in an educational psychology department. It was hypothesized that the GRE-A would be a more efficient predictor than faculty ratings on a…

Concerned with the relationship of a print awareness indicator to subsequent reading achievement, a study measured changes in the development of print awareness across age and grade levels as well as across time. It also compared the levels of print awareness in lower ability and educationally disadvantaged children in second and third grades to…

The relationship was investigated between test scores obtained from the Iowa Tests of Basic Skills (ITBS) and the Iowa Tests of Educational Development (ITED), and the grade point average (GPA) at the high school and college level. The data used were unique in providing a longitudinal comparison of college students' performance with the results of…

Studies comparing neuromotor and mental functioning of normal and disabled populations have shown that lower cognitive functioning is significantly related to lower motor functioning for retarded or disabled children but not for normal children. In an effort to further examine the relationship between these two functions, a study was conducted of…
