Abstract

Registered examinees for the GRE General Test answered open-ended sentence-completion items. For half of the items, participants received immediate feedback on the correctness of their answers and up to two opportunities to revise their answers.

In addition, the reliability of the revised scores and their correlation with GRE verbal scores were higher. The possibility of using revision scores as a basis for measuring potential future learning is discussed.
