1. One of the BEST ways is right here with IDEA! Go to your profile and there’s an area on the right hand side (tab), that you can post workshops and courses as well as dates/locations/time and a brief bio of your certifications.
2. Utilize your social media (i.e. Facebook, Twitter, etc) and post on your page your certification as well as invite people on your facebook list.
Good luck and success as the preschooler certification is something that we can use!
I looked at your profile and found the FuzeKids program. Looks great. One thing I would suggest, though. See whether you can make this continued education for existing certifications. Many instructors look for CeC opportunities. Here is a link to ACE’s application form. https://www.acefitness.org/conedproviders/default.aspx.
