The official NEBB Formula Chart was coordinated and upgraded by NEBB Technical Advisor, Don Fedyk and vetted by the NEBB Committee Chairs, NEBB Certification Board and the NEBB Exam Development Committee.

It is a useful tool for Candidates pursuing certification as well as a reference guide for those Certificants who are on-the-job. The official NEBB Formula Chart is date-stamped and signed by NEBB’s Technical Director and will be reviewed each year.
