Which gyms accept certifications from the International Sports Conditioning Association?
You do not say whether you are talking about personal training or group ex. I will assume in my answer that you are talking about training, but the general points I make can be taken for either thing.
There is a great tool for comparing personal training certifications on the ACE site, if you are interested in looking at the types of things that employers look for : http://www.acefitness.org/fitness-certifications/personal-trainer-certif…
There are a lot of ‘certifications’ out there. Some may be what we used to call a workshop…. a couple of hours of instruction, but if you call it a certification people feel it sells better and is a better value. Some may be totally online, including the exams. Some may not have a proctored exam (one where someone makes sure you don’t look up answers while you take it), some are not NCCA accredited.
Where I have worked what I have seen is that that NCCA piece seems to be the baseline. Though an exception seems to be made for AFAA in a number of places, otherwise if you certify with an agency that is accredited specifically with NCCA it means that there is a certain baseline…. so the manager doesn’t have to know about every one of the multitude of certifications that are out there, but can be sure it meets minimum standards. Like with yoga if the program is on the registry it will be accepted in most places.
I have no personal familiarity with the organization you mention.
I am an ISSA Certified Fitness Trainer and I have not had a problem with organizations not accepting it. I took my training in 2003 and ISSA is better known now. As far as accreditation goes this link will explain why ISSA chose to take a different route. http://www.issaonline.edu/why-issa/accreditation.cfm
ISSA has also been very good about accepting continuing education credits for college courses and from other associations.
