Recommended Herpetology Programs?

Hello!
I’ve recently decided I want to get a better education regarding herpetology. I graduated in 2016 with a BS in Animal Science and I’ve interned/worked at several zoos, but my knowledge with reptiles specifically is mostly self taught.

Is anyone familiar with online programs or certifications for herpetology that they would recommend? (Or any you would NOT recommend, that would be equally helpful) I’m not looking to get my Masters or anything that intensive, just programs I could do over 3-6 months to have a better herp foundation. Right now I’m looking at the Master Herpetology Certification Program offered by the Amphibian Foundation.
Thanks!
