The CIH exam consists of 150 scored items and an additional 30 experimental questions. The multiple-choice questions are designed to assess the knowledge and skills required to function as a certified practitioner in the field. The exam is 5.0 hours in length with an optional 30-minute break in the middle. After you have been approved to sit for the exam and paid your $350 exam fee, you will be able to schedule your exam with Prometric.
Examinations are offered at Prometric testing locations during two windows -- April-May and October-November. You can schedule an exam anytime within those windows (depending on the hours of your chosen test center - some are open Sundays, some aren't).
