# Update a group specialty's effective or termination date

`PUT /groups/{id}/specialties`

Updates the effective date and/or termination date of an existing group specialty association, identified by tenantGroupSpecialtyId in the request body. At least one of effectiveDate or terminationDate must be supplied. This is a partial update — an omitted date field is preserved from the existing record, not cleared. For bulk specialty management (adding new specialties and updating existing ones in a single call) use PATCH /groups/{id}/specialties.
