- If a learner does not achieve a ‘Pass’, the learner may re-sit the unit(s) in which they have been unsuccessful providing that this happens within the 5-year enrolment period.
- However, each re-sit will incur an additional fee. Learners may re-sit unit(s) at any time within their enrolment period. This includes re-sitting successful unit(s) to try to improve the qualification grade. When all three units have been successfully completed, learners will need to inform NEBOSH of their intention to re-sit the successful unit(s) within 20-working days of the results declaration date for the final successful unit. There is no limit to the number of re-sits which can be taken within the enrolment period.
- If a learner sits a unit more than once, the highest grade achieved will count towards the final qualification grading.
- If a learner registers for any unit of the International Diploma whilst awaiting a result from a previous
assessment, the learner cannot then request a refund of the registration fee if the awaited resulted is a ‘Pass’ (except in the case of an Enquiry About Result).
