this paper reports on the use of can do statements (CDS) for the development of learning materials to prepare japanese university students for the Test of english for international Communication (TOEIC). These learning materials have been made available on ATR CALL BRIX (www.atr-lt.jp/products.brix/index.html), a www based courseware with a learning management system(LMS) which contains study logs, achievement rate reports on student-set goals, the identification of students' weak points, and advice on test-taking strategies. CDS, the specific behaviors that an examinee at a certain score level can be expacted to be able to perform in English have been conventionally used as descriptors to explain test scores to educators and employers who use TOEIC scores to assess the English proficiency levels of students and prospective employees. Official CDS published for the TOEIC 600-score level, and the CDS, at comparable levels, for the society for Testing English Proficiency test (STEP), and for the Common European Framework of Reference for Languages (CEFR) were used to complie this study's CDS set. The CDS were given to 592 students as a self-report inventory immediately . after they took a TOEIC test. the CDS were then used to develop TOEIC learning materials which were trialed in a TOEIC skill- building course for 22 students. According to comparisons of pre- and post- course TOEIC scores. it was concluded that the use of CDS-based TOEIC learning tasks, which include advice on test-taking strategies, in a www-based course may help students improve their TOEIC scores.
