Units NGC1 and NCC1 are taught units each assessed by a two-hour written examination. Each written examination consists of ten ‘short-answer’ questions and one ‘long-answer’ question. All questions are compulsory. Candidate scripts are marked by external examiners appointed by NEBOSH.
Unit NCC2 is assessed by a two-hour practical examination carried out in the candidate's own workplace to test the application of taught health and safety principles in a construction workplace. The assessment must normally be taken within 14 days of a written examination. The practical examination is internally assessed by the course provider and must be marked by an experienced and qualified safety professional.
