Honestly I don't think there is any centralized database. Gyms that participate in TOPs vary from year to year. My piece of advice is not to worry about finding a gym that does TOPs. Just look for a gym that has a solid track record of developing athletes to L10 and/or elite. Look in the area that you want to move to, see the gym(s) and look up on MSO or Mymeetscores how that gym has performed. With a little bit of sleuthing you reasonably deduct the strong gyms. Then of course visit those gyms.
You can find a lot of mixed opinions around here about TOPs and they are all valid. Some gyms really just view it as an additional revenue stream and just a mechanism to charge for extra practice/conditioning. Other gyms are more sincere about using TOPs to develop the athlete. Still, even then there are mixed reviews on the benefits of TOPs since a significant component seems to focus on physical ability (can they do a rope climb) versus actual skills. I do believe a gym that does it right can really help with a solid foundation on form. But in the long run I think you are better served with a gym that does a good job of athlete development, they will get you where you need to be, whether that is elite or DP and don't worry if they do or do not have a TOPs program.
