The certification scheme for personnel (CSWIP) is a comprehensive program that allows people to verify their knowledge and competence in their field of activity through examination and certification. Welding inspectors, welding supervisors, welding instructors, plant inspectors, under water inspectors, welders, and NDT personnel are all covered by CSWIP.

CSWIP is overseen by the certification management board, which serves as the scheme’s governing board for certification in accordance with the needs of the industries it serves. The certification management board is based in the United Kingdom. Members of relevant industrial and other interests are represented on all CSWIP boards and committees.
