[3] All applicants complete a common recruitment test (RT) with varying score thresholds depending on branch, before having a formal 'sift' interview.

The Board consisted of a range of academic, physical, mental and aptitude tests assessing suitability for future employment.

Each Board was supported by a senior rating or senior NCO, responsible for the administration and briefing of candidates Candidates arrived at around midday - the majority of day one was based around acquainting them with the assessments to be completed the following day, completing the fitness test, and providing an opportunity for the syndicates to bond as a team.

Finally, candidates had free time during the evening and were encourage to practice the techniques for the PLTs and bond with their syndicate in order to stand the best chance the following day.

Syndicates attempted tasks selected from a range of scenarios: i.e. load carries across chasms or pools using supplied equipment.

Here, over a period of thirty minutes, candidates were interviewed about their past achievements, experiences of difficulty overcome, and questioned as to their motivations in joining the Naval Service.

Where a candidate has passed but has not been selected, they may be offered an alternative branch (should there be shortages), or they may be invited to reattend AIB after 12 months when there may be more vacancies.

Where a candidate has not achieved a pass they may be invited back again (usually after a period of at least 6 months) if the board president believes the individual has future potential, or they may be advised that they should not return.
