A challenge for many EAP teachers working on pre-sessional programs is to find ways to reconcile the dual aims of preparing students for university study and for the IELTS test. The study described here seeks to provide some guidance on this issue through an analysis of the type of writing required in the two domains. We compared the standard IELTS Task 2 rubric with a corpus of 155 assignment tasks collected at two Australian universities and found that whilst IELTS writing bears some resemblance to the predominant genre of university study-the essay, there are also some very important difference. Our findings suggest that the type of writing the test elicits may have more in common with certain public nonacademic genres, and thus should not be thought of as an appropriate model for university writing. We conclude that it is probably best to deal with test preparation and the broader EAP writing curriculum within separate programs. (Contains 11 tables and 1 figure.)
