The NKBA developed its certification programs as a way for kitchen and bath professionals to enhance their careers and market themselves as experts in their field. NKBA certification is based on in-depth testing and extensive industry experience. The NKBA’s certification examinations are developed in conjunction with the NKBA’s Exam Development Committee. The primary body of knowledge for NKBA certification is the nine volume Professional Resource Library and the NKBA Kitchen & Bathroom Planning Guidelines.
