Legacy Certifications

Our legacy certifications are long standing and well recognized, not just within the industry but by our industry stakeholders as well. This brand equity has evolved over a considerable period of time; 75 years for the AHC, 35 years for the CDC, and 10 years for the EHC certifications. These legacy certifications will continue to be offered until the new certification program is fully rolled out to the industry. Use DHI’s Credentials + Certifications Guide to promote your individual and company marks of excellence to your customers.
