To demonstrate that some methods used to assess item fit can be applied to assess person fit and vice versa, performance of a chi-squared item-fit statistic was compared with that of a likelihood-based person-fit statistic for examinees and items under Monte Carlo conditions. (SLD)

Examines patterns of enrollment, choice, and degree attainment of undergraduate students attending college between 1975 and 1986 in five metropolitan areas with private institutions as well as public systems enlarged during the postwar period.

A method for predicting freshman performance based on high school grades allows calculation of any student's likely grades in a similar university course. The method is contrasted with several more traditional predictive methods and examined in a study of 3,734 University of Western Australia students. (MSE)

Variability of aided sound field thresholds (ASFTs) was examined in 30 hearing-impaired children comprising 2 age groups (5-9 and 10-14 years). Findings showed that 2 ASFTs would have to differ by more than 10 decibels across signal test frequencies to attain statistical significance. (Author/DB)
