I believe that each and every certification needs to have a practical part in order for someone to receive those credentials. So far, the 1 or 2-day certifications (such as RKC, CrossFit, FMS, etc.) are the ones that require their students to do a practical test as well unfortunately (participate with hands-on training). I also believe that if we as an industry are going to require health insurances to include us on their lists as providers and pay us for taking their clients/patients, then the certifications will need to become a lot more detailed and a practical exam will definitely help. Anybody can read and memorize book material, but can they actually deliver it and explain it in a safe and correct form when they have too?
