Course Description

With increased national demand for comprehensive retrofits, the RESNET Board of Directors has made it a requirement that RESNET certified Raters must pass the Combustion Safety and Work Scope written exam and simulation prior to December 31st, 2014, to maintain the Rater Certification. This 7-hour online training designed for Raters who are also BPI certified, is conveniently spaced over just 1 week and will prepare attendees to take and pass the tests.

All existing Raters must pass both the written and simulation CAZ exams by January 1, 2015, to maintain their Rater certification.

This RESNET Combustion Safety and Workscope Training fulfill this requirement.

*Raters who are not BPI analyst certified will need an additional 2 hours of field training by the end of 2014 to comply with RESNET standards.*
