CEU is a standardized continuing-education unit while PDH is commonly used for professional-license development hours; acceptance and conversion rules are controlled by the licensing authority.
The difference between CEU and PDH
The practical difference is the governing definition and where the credit is accepted. CEU is a standardized continuing-education unit while PDH is commonly used for professional-license development hours; acceptance and conversion rules are controlled by the licensing authority.
Do not assume automatic conversion
Keep the original unit or credit label from the completion record. Convert only when the receiving licensing board or certification program tells you how it treats the activity.
What to record
Save the provider, activity title, date, original credit unit, amount, category, certificate, and the authority rule you relied on. That makes later audits and multi-credential use easier to verify.
Sources and verification
Defines one CEU as ten contact hours of participation in an organized continuing-education experience.
