Units IGC1 and IGC2 are taught units each assessed by one 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 IGC3 is assessed by one two-hour practical examination carried out in the candidate's own 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 externally moderated by NEBOSH.
The assessment is available in English, Arabic, Russian and Turkish. The course includes a requirement to write a short report. If students choose to take the assessment in English NEBOSH recommends that students should reach the equivalent of a scoring of 6.0 or higher under the International English Language Testing System (IELTS).
