Pearson Test of English Academic (PTE Academic) has six item types that assess academic writing either independently or integratively. This research focuses on evaluating the construct validity and effectiveness of the six writing item types. Exploratory Factor Analysis was performed to examine the underlying writing constructs as measured by the six item types. Item scores for different writing skills were subjected to Rasch IRT analysis. The difficulty of the item types was estimated and the effectiveness of each item type was evaluated by calculating the information function of each one. The results identified two writing constructs: an Analytical/Local Writing construct and a Synthetic/Global Writing construct. The study has implications for test developers on the use of multiple item types and their effectiveness, and for test users on how they can improve their writing skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
