No, the Certificate IV in Kinesiology is no longer a prerequisite for the Diploma course, as it was withdrawn in December 2015.  

If you have already completed your Certificate IV in Kinesiology you will receive credits towards your Diploma.   You will also be eligible for professional indemnity insurance once you have completed the Certificate IV in Kinesiology or our ACVH equivalent, so you can start earning an income while you study your Diploma.
