Since the inception of computer assisted language learning (CALL), computers have been successfully used to provide leaning and assessment opportunities for groups or individual learners. This article describes a use of computer that is fundamentally different to most CALL approaches, and yet contributes to language learning. While presenting a case study conducted in higher education in the Gulf of Arabia, the paper builds a strong case for computer assisted vocabulary profiling as a means of objective needs analysis and language program evaluation. This approach is based on a lexical comparison of learner corpora with the corpora of teaching resources. The software used for this purpose is The Compleat Lexical Tutor. (Contains 3 figures.)
