Completion of Solairgen training courses will provide the individual with an expanded knowledge and understanding of the construction trade. These courses are supplemental and not primary to become a licensed professional construction contractor. The course takes approximately 30 hours to complete. It is the prerequisite to our more advanced level courses and the prerequisite to register for the NABCEP Associate Credential exam. The 30 hours may not be used for NABCEP professional and specialist requirements. A passing score on the Associate Credential exam provides the student with 18 NABCEP credit hours. Your activity in the course is time stamped for minimum required active participation.
