Certification & Recertification :
After successful course completion, all trainees are required to sit for both open and closed book written examinations in order to be certified as an IPC/WHMA-A-620 Certified Standards Expert (CSE). The examinations consists of three papers; namely the Enhanced Policy and Procedures Exam, General Knowledge Exam, and Standard Endorsement Exam.
The General Knowledge exam consists of thirty multiple-choice questions, which requires the trainee to complete it within a closed-book environment. On the other hand, the Standard Endorsement Exam consists of seventy multiple-choice questions and it is an open-book test that must be completed within two and a half hours. Upon successful completion of these examinations, the trainee will be awarded with a CSE Certification that is valid for two years. The training program provides an invaluable opportunity for professionals to enhance their knowledge and skills in becoming a Certified Standards Expert. The thorough training session combined with the carefully designed examinations can equip the trainees with the necessary expertise required for a successful career in this field.
