In 2007, the International Wildlife Rehabilitation Council (IWRC) formed the Certified Wildlife Rehabilitator™ (CWR™) program and an independent Certification Review Board (CRB) responsible for the evaluation and certification of wildlife rehabilitators. The CWR™ CRB endorses voluntary certification by examination for all wildlife rehabilitator professionals, including those who act as volunteers and are not employed in the field. Individuals who meet CWR™ CRB requirements are eligible to take this examination. Certification as a professional wildlife rehabilitator distinguishes individuals who demonstrate a competent level of professional practice and conduct and a high quality standard of care.
