Home Energy Professional Retrofit Installer Technician Training

The Home Energy Professional (HEP) Retrofit Installer Technician (RIT) course is a comprehensive, 5-day training designed to prepare students to challenge the Written and Practical Exams for the HEP RIT Certification. This Certification is based on the RIT Job Task Analysis, an industry-led collaboration directed by the National Renewable Energy Laboratory (NREL) and the U.S. Department of Energy (DOE), which defines the knowledge, skills and abilities necessary to perform the job of a Retrofit Installer Technician working in the Weatherization or Home Performance industries.

To achieve the HEP RIT Certification, a student must receive a passing score on two (2) exams: a Written Exam and Field Exam. Students seeking this Certification must meet additional prerequisites in order to qualify to challenge the exams (see Prerequisites section below) and must provide proof of approval from BPI in order to take the exams.

Please note that for this course, the cost of the exams is NOT included in the price and must be paid for and scheduled separately. This training has been approved for 8 BPI Continuing Education Units. Additional information regarding this and other Home Energy Professional Certifications may be found here: Home Energy Professional Certifications.
