This eight day program meets the RESNET National Standards for training and certification of HERS Rater. This is a lecture lab course. Topics will be presented in a classroom setting and then followed up with student involvement in the lab. The class will be geared to little or no previous training in the field. Student participation is very important. This class includes two of the five probationary ratings required to be conducted in the training class. The online national HERS Rater exam will be given on the last day of the class as will the ResCaz Simulation exam. After the successful completion of the remaining ratings, confirmed by the instructor, the student will become a certified Rater.

Grading criteria and passing score

Students earn certificates of attendance by attending the training. The national certification exams offered at the end of the course are evaluated separately and do not contribute to a grade for the course.
