The AAT assessments differ for each paper. Level 4 papers include extended writing tasks.  The assessments vary between 1-2.5 hours long, depending on the subject and level of the exam you are sitting.  The questions in each assessment are chosen from a large bank and differ in each exam.  The competency level for AAT assessments is set at 70%.  Competence must be achieved in each section of the overall test to pass the exam.  Your results will be confirmed on your MyAAT account. A results' breakdown is available from your exam centre.
