Evidence can be in the form of a certificate of attendance, signed supervision attendance record, a letter from a supervisor confirming dates and times, journal subscription receipts, documents or a statutory declaration. It is recommended to attach evidence at the time you are recording your CPD. If you are ever selected to participate in an a CPD record audit, you will be required to provide proof of your CPD activities. The AASW recommends that you keep records of evidence of CPD for a minimum of 2 years.
