Best linear prediction (BLP) and penalized best linear prediction (PBLP) are techniques for combining sources of information to produce task scores, section scores, and composite test scores. The report examines issues to consider in operational implementation of BLP and PBLP in testing programs administered by ETS [Educational Testing Service].

In this study, differential item functioning (DIF) methods utilizing 14 different matching variables were applied to assess DIF in the constructed-response (CR) items from 6 forms of 3 mixed-format tests. Results suggested that the methods might produce distinct patterns of DIF results for different tests and testing programs, in that the DIF…

Investigated how well the generalized and Rasch models described item and test performance across a broad range of mixed-item-format test configurations (six tests from two state proficiency testing programs). Evaluating the impact of model assumptions on the predictions of item and test information permitted a delineation of the implications of…

Used a curriculum-based measurement (CBM) of reading aloud from narrative passages to predict performance on statewide achievement tests in reading and mathematics. Results for 51 students (third graders in the second year of the study) provide initial support for the use of timed oral readings to predict students' performance on statewide…

Deals with the methodology and practices for Environmental Impact Assessment (EIA). Describes the EIA process, prediction process, alternative assessment methods, training needs, major activities, training provision and material, main deficiencies and the precautions, and real world training examples.

The relationship between student GPAs and scores on the National Board of Chiropractic Examiners tests was investigated in an effort to determine if the chiropractic curriculum was properly preparing students to be licensed. The study found that there was a significant correlation between GPAs and board scores. (Author/MLW)
