This paper analyses new research into learner-assisted testing. The results of this research, in addition to advances in computer technology and programming, have opened up the possibility of helping students to learn more effectively by providing immediate feedback or further information in the form of clues or hints. The implications of these developments regarding a formative approach to assessment and autonomous learning are reviewed. Finally, innovative approaches within computer-based assessment of language learning, such as modules entirely taught through the use of computer courseware and CAL methods, and applications of Intelligent Tutoring Systems (ITS) to foreign language learning, are discussed.
