The exam is recommended for Home Health Nurses, Therapists, and other home health professionals who conduct comprehensive assessments, score OASIS items, audit clinical records, or educate and orient staff.

Here are 5 benefits to becoming a certified OASIS specialist:

  1. Becoming a part of the COS-C community is an investment in your career that differentiates you from others in your agency, organization and market. It demonstrates your willingness to take action to learn and excel.
  2. The COS-C exam is the premier test of one’s understanding of CMS’ OASIS guidance. The nationally recognized COS-C designation can then be leveraged to increase your credibility with audits, education, orientation, or data collection within your organization.
  3. By attaining and maintaining your COS-C certification, you will establish a solid foundation of knowledge, and a process for regularly updating and refreshing your knowledge, even in the ever-changing environment of OASIS.
