The ISAT test is a 3 hour computer-based multiple choice test. The test is presented in units, with stimulus material followed by questions. There are 100 questions with 4 or 5 answers from which the candidate is asked to choose the most appropriate response. There is only one correct answer, with no marks deducted for incorrect answers. ISAT is not a test of subject specific knowledge. Rather, it aims to assess a candidate's 'critical' and 'quantitative' reasoning skills.
'Critical Reasoning' (CR) - involves comprehending and analysing information; understanding, applying and extending ideas; drawing appropriate conclusions; and evaluating arguments. These questions use material from the humanities and social sciences.
'Quantitative Reasoning' (QR) - involves analysis and application of information; drawing conclusions and making decisions; and solving problems. These questions use material from the mathematics and sciences.
