Certification in clinical engineering is governed by the Board of Examiners for Clinical Engineering Certification. To be eligible for certification in clinical engineering, a candidate must hold appropriate professional or educational credentials (an accredited engineering or engineering-technology degree) have specific and relevant experience and pass an examination. The Examination for Certification in Clinical Engineering involves a written examination composed of a maximum of 150 multiple-choice objective questions with a testing time of three hours, and a separate oral exam. Particular weight is given to applicants for who are already licensed as registered Professional Engineers (PE), which itself has extensive requirements (including an accredited engineering degree and engineering experience). When the candidate passes the examination and oral exam they will be certified by the Board of Examiners as a Certified Clinical Engineering (CCE).
