The only thing constant in life is change, and this rule applies equally to the various certification exams that you might be preparing for.

The current blueprint, which has been in effect since July 2013, was reviewed and a Job Task Analysis (JTA) performed. This JTA involved current CHMMs providing feedback on what tasks and skills are necessary for a minimally qualified hazardous materials manager to be competent.
