If you did not pass the exam on your first attempt and would like to re-test, please submit a CWCA, CWS or CWSP Re-Test Application online. Candidates who wish to retake an exam must wait 30 days after their previous exam date before their new three-month eligibility window begins. Candidates may submit a Re-Test Application prior to the end of the 30-day waiting period; the new three-month eligibility window will start 30 days after their previous exam date. Candidates who wish to test more than three times will need to provide documentation of 20 CEUs in wound care for each exam attempt. Candidates may submit a Re-Test Application to retake an exam for up to 2 years from their original exam date.
