If you failed the Pro course (ATC or ITC), it means that you did not meet the requirements to pass the course and that you are not ready to follow an internship yet. This decision is final and up to the Assistant Trainer's or Examiner's judgement with confirmation of the Training Department for special cases. Note that none of the fees are refundable.
If you wish to make a new attempt, first of all ensure that the reason of your failure allows you to do another ATC or ITC (if you are not sure, please directly ask to the IKO Office). You will then need to attend another event. To find a Pro course event, you can search on the Training Calendar. Once you find the course that you want to join, contact the IKO Office at office@ikointl.com to book your course. Be aware that the IKO fees are only going to be $90 USD for your second attempt.
