In order to determine the “Date Deemed Skilled”, VETASSESS applies DIBP's definition of closely related employment; to the nominated occupation. DIBP defines closely related employment as paid employment of at least 20 hours per week in an occupation which has the same skill level and draws on a similar skill set and subject matter as the nominated occupation. Usually closely related employment is an occupation which is in the same Unit group of ANZSCO as the nominated occupation.
