National Environmental Balancing Bureau (NEBB) Certified Professional (CP) Practice Exam

In NEBB’s TAB program, a Certified Technician performs the field testing and adjustments, but supervision and accountability come from a NEBB Certified Professional. The CP is the credentialed individual who reviews data, ensures procedures follow NEBB standards, and signs off on the TAB work. This setup keeps field work aligned with quality controls and gives the CT scope to operate under the CP’s oversight. The Certified TAB Firm is the employing organization, and the TAB Report is the document produced; Outside Air isn’t a supervisor. The essential point is that the supervision of a CT must be provided by a NEBB Certified Professional.
