CSCS was set up to help the construction industry to improve quality and reduce accidents. CSCS cards are increasingly required as proof of occupational competence by contractors and both public and private clients. The CSCS card is the industry's largest scheme and covers 220 occupations including trades, technical, supervisory and management.
CSCS cards list the holder’s qualifications and are valid for either three or five years. It also shows they have health and safety awareness. Most contractors and clients now require proof of competence with a CSCS card, before allowing workers onto their sites.
