Frequent Deficiencies (Revised 2-23-2024)

Revision History

To help your facility avoid common pitfalls, the table below outlines deficiencies that are frequently found during the accreditation process. These deficiencies must be addressed before a facility will be granted accreditation. Please note that other serious deficiencies not frequently seen and therefore not listed here may also require corrective action and documentation prior to accreditation.
