Established in 2004, the Certificate for OASIS Specialist-Clinical (COS-C) Exam is the premier nationally standardized, psychometrically validated test that evaluates a clinician’s knowledge of CMS’ OASIS guidance.
Effective October 1, 2016, ALL COS-C Exams administered at computer-based testing sites or via proctored paper and pencil administrations will utilize a new exam updated for OASIS-C2 (effective January 1, 2017). The OASIS-C1/ICD-10 version of the exam will not be available by any testing means after September 30, 2016.
Candidates taking the COS-C Exam in the month of October 2016 should be aware that the reporting of exam results will be delayed in order to allow OASIS Answers to define and set a fair and equitable criterion-referenced passing score for this updated exam version.
Completion of the process relies on analysis of data from a sufficient number of OASIS-C2 candidates and input from a group of OASIS Subject Matter Experts, under the direction of the Exam Psychometrician. OASIS Answers expects to have sufficient data collected to allow analysis and validation by November 1, 2016, and expects that exam results for candidates testing in October will be mailed by November 21, 2016.
Candidates achieving a successful result on either version of the Exam (OASIS-C1/ICD-10 or OASIS-C2) will be awarded the COS-C designation. The designation is valid for three years, with retesting prior to expiration required for renewal.
Thank you for your commitment to OASIS accuracy.
Linda Krulish, PT MHS COS-C
President, OASIS Answers, Inc.
