The DC Board will accept Calypso courses for credit. (For verification please see board document here)
Non-DC approved Certificates must state explicitly that the Courses are approved by another Appraisal Regulatory body or the Appraisal Qualification Board’s (AQB) Course Approval Program (CAP).
Calypso certificates include approvals from states Nationwide. If you are licensed in more than one state, you may use the course for credit in approved states.
