This is such important work, thank you for doing it!
While each state has its own requirements, all of the states whose educator licensure I am familiar with (Illinois, Iowa, Ohio, Michigan, Massachusetts) maintain a list of state-approved continuing education providers. In order to receive continuing education credits that count toward licensure, the teacher must go through an approved provider. There are often processes for submitting professional development from a provider not on the list, for example from out of state, but information about those processes is not generally transparent or easily accessible.
One way to deal with this could be to partner with a college or university that has a teacher licensure program in each state to co-sponsor or co-host your programming. They are typically on the state-approved lists and could potentially help you with the continuing education paperwork requirements.
As a neurodivergent teacher educator, I'd love to learn more about your programming!
