Testimonials

  • I recently completed my cert 3 with FEO and had a very positive experience. I liked that the course plan and activities were clearly laid out and easy to follow. The team was always easily accessible for questions and always completed assessment marking in a timely matter. I'd recommend FEO to anyone who's interested in completing their Cert 3 at their own pace alongside other commitments/work.

  • Just completed my cert 3 with FEO and onto my cert 4, I really enjoyed doing the practical intensive weekend and the experience of getting to be immersed in the industry. It was great to be able to manage completing my certificate around my busy schedule so I would recommend anyone who's sitting on the fence to give it a go, it's actually managable to accomplish!

    Certificate III in Fitness
  • I just finished my Cert 3 with FEO. I enjoyed doing the course and only wished that I could have applied myself a little more. It was a very busy time for me but now things have settled down I look forward to completing my cert 4. The option for online face to face work was great. The opportunity to complete the practical components in one weekend definitely made it less stressful. That weekend enabled me to meet other students and create a couple of contacts. The support from the student administration was excellent. Cheers

  • I enrolled in my Cert IV with FEO after completing my Cert III and Group Fitness Certification with other providers years ago. AusActive required nine subjects to be re-completed through bridging units. I expected this to be a hurdle, although FEO made the process straightforward. Assessments are marked quickly, and any questions about content or the course are answered clearly and concisely. The content is friendly, engaging, and well structured, with none of the clunkiness I experienced with other providers. I am also completing the Older Adult Population CEC modules and enjoying those as well.
