Once you have submitted your ACAT assessment, an assessor will be assigned your case. In most cases this assessment will take between 45 and 75 minutes. It can take up to six weeks to get an ACAT assessment once you apply, depending on how urgent your situation is and the level of care you need. If your situation is urgent because you are at risk of harm or in a crisis situation, an ACAT assessment can be completed within two days.
