The Montana Weatherization Training Center is a registered Building Performance Institute (BPI) Testing Center. We offer proctoring for several BPI written and field exams including Energy Auditor, Quality Control Inspector, and Healthy Homes Evaluator. While we recommend taking our respective courses to prepare our students for the exams, it is not required.

To purchase a proctored exam, please use this page to register for exams. Students will need to contact an instructor to schedule a time to proctor the exam(s). We strive to keep our schedules flexible to accommodate the needs of our students.

In the wake of COVID-19 concerns around travel and social gatherings, the Montana Weatherization Training Center (MWTC) now offers remote test proctoring of written examinations for most BPI certifications: Quality Control Inspector (QCI), Healthy Home Evaluator (HHE), Building Analyst (BA), Heating Professional (HP), Envelope Professional (EP).

Unfortunately, BPI currently does not currently allow remote proctoring for Energy Auditor (EA) exams (as of February 2021).

We are happy to proctor EA or any other exams in-person utilizing proper protective measures at our Bozeman Training Center.

Please find a step-by-step tutorial on how to prepare for a virtual exam on our website at
