The Certificate for OASIS Specialist - Clinical (COS-C) is valid for three years, with renewal testing required within three years of your initial exam date to maintain the designation and qualify for the discounted renewal rate.
There is only one version of the COS-C exam at any given time. Thus, there is no separate certificate renewal exam.
Reduced Certificate Renewal Fees
The reduced fees only apply if the renewal exam is taken BEFORE the 3 year anniversary of the previous exam when the COS-C was granted.
*As a courtesy, all COS-Cs are given to the end of their expiration month to retest
Lapse of Designation
If a COS-C does not sit for the COS-C exam by the end of three years after the date of their last successful examination, they are no longer considered a COS-C in good standing and must discontinue using the COS-C designation.
*Upon successful renewal testing, the COS-C is considered in good standing and may continue to use the COS-C designation behind his/her name for the additional period of three years.
In order to stay current with the most recent CMS guidance, all COS-Cs are encouraged but not required to participate in continuing OASIS education. The COS-C designation does not currently carry any specific continuing education requirement to maintain the Certificate for OASIS Specialist-Clinical designation.
Given the dynamic nature of OASIS, it is highly recommended that all OASIS professionals establish a strategy for maintaining awareness of the ongoing changes in CMS guidance.
