Lansing, MI -- One of the most frequently asked questions from those who are considering pursuing the Certified Industrial Hygienist® (CIH®) credential or preparing for the examination is what resources and references have Diplomats found useful in the past?  This information can be extremely beneficial before taking the 5 1/2 hour written exam which consists of 200 multiple choice questions designed to assess the knowledge and skills required to function as a certified practitioner in the field.

While the American Board of Industrial Hygiene® (ABIH®) does not endorse specific references or study aids, it has compiled a list of those items named by previous examinees who passed the examination.
