All versions of CAN involving staff completion (i.e. CANSAS, CAN-R, CAN-C) can be used without any formal training by mental health professionals. Each version contains a page outlining how to rate responses and, in the CAN-R and CAN-C, every rating has anchor points for guidance. Reading through the CAN-R or CAN-C will give the staff member a good overview of the approach used, and a relatively good assessment can be expected from the first use. The main improvement in subsequent assessments is likely to be in the time taken for assessment, which will reduce as familiarity with the measure increases.
