On the seminar certificate you received after the seminar, if your trainer submitted the course for CEU approval at a Credentialing body, that would be noted on your class certificate. If the Credentialing body is not listed on the seminar certificate, then the ADDC seminar is not CEU approved and the trainer did not present the ADDC curriculum to your credentialing body to get CEU approval.
The CADDCT trainers are not required to submit a course for CEU approval. There are hundreds of credentialing bodies, and it is up to the trainer to pick which credentialing bodies to apply for CEU approval, should they choose to do so.
If you do not see your credentialing body on the seminar certificate, I recommend that you contact your credentialing body to ask if they will accept the 7 hours towards the required CEUs you need to renew your license or certification.
