A Psychometric Measurement Model for Adult English Language Learners: Pearson Test of English Academic
Pae, Hye K.
Educational Research and Evaluation, v18 n3 p211-229 2012
The aim of this study was to apply Rasch modeling to an examination of the psychometric properties of the "Pearson Test of English Academic" (PTE Academic). Analyzed were 140 test-takers' scores derived from the PTE Academic database. The mean age of the participants was 26.45 (SD = 5.82), ranging from 17 to 46. Conformity of the participants' performance on the 86 items of PTE Academic Form 1 of the field test was evaluated using the partial credit model. The person reliability coefficient was 0.96, and item reliability was 0.99. The results showed that no significant differential item functioning was found across subgroups of gender and spoken-language context, indicating that the item data approximated the Rasch model. The findings of this study validated the test stability of PTE Academic as a useful measurement tool for English language learners' academic English assessment.
