InterNACHI makes entrance requirements even tougher.

 
InterNACHI, the International Association of Certified Home Inspectors, recently raised its entrance requirements by:
1.  Increasing the passing cut-off score of its inspector examination to 80.  This is predicted to reduce the passing rate form 46% (currently) to 38%.
 
2.  Requiring the completion of its online electrical course including passing of the quizzes and final electrical exam as a condition of membership.
