This study examines the predictive validity of the TOEFL iBT with respect to academic achievement as measured by the first-year grade point average (GPA) of Chinese students at Purdue University, a large, public, Research I institution in Indiana, USA. Correlations between GPA, TOEFL iBT total and subsection scores were examined on 1990 mainland…

Data from 787 international undergraduate students at an urban university in the United States were used to demonstrate the importance of separating a sample into meaningful subgroups in order to demonstrate the ability of an English language assessment to predict the first-year grade point average (GPA). For example, when all students were pooled…

The assumption called PIRC (proportional item response curve) was tested in which PIRC was used to predict item scores of selected examinees on selected items. Findings show approximate accuracies of prediction for PIRC, the three-parameter logist model, and a modified Rasch model. (12 references) (Author/LB)

An investigation of person dimensionality attempted to identify student clusters relating to demographic variables and their core on a university English-as-a-Second-Language placement examination. The two genuine clusters for students with scores in the top or bottom 27 percent could not be accounted for solely on an ability basis. (CB)

Analysis of the English language aptitude test scores of 824 full-time Jewish students studying at a major Israeli university evidenced both slope and intercept bias by ethnicity (Western or Oriental), and by gender, tending significantly to overpredict or underpredict students' first-year cumulative grade point averages.

Examines the validity of the cultural bias contention with respect to English aptitude tests by looking at test scores of Jewish and Arab students applying for admission to a college in Israel. Results show evidence for differential construct or predictive validity of test scores as a function of cultural group membership. (31 references)…
