The exam is ideal for Home Health Nurses, Therapists, or other home healthcare professionals responsible for conducting comprehensive assessments, coding OASIS items, auditing clinical records, or educating and orienting staff.

Why Get COS-C Certified?

You can turn your OASIS expertise into a recognized credential, proving that your OASIS knowledge goes beyond familiarity. The COS-C designation validates the accuracy, judgment and confidence you bring to assessments every day. It signals a higher level of commitment and credibility and distinguishes clinicians, educators, QA reviewers, and leaders who take accuracy seriously.
