Every planning exercise candidates face, whether at OASC, AOSB, or AIB, is built with gaps in it. Resources go unaccounted for, timings are vague, and key details are sometimes simply left out. This isn't a flaw in the exercise, it's the point of it. Boards want to see how candidates think when the picture isn't complete, because that's closer to how real decisions get made than any exercise with all the facts laid out neatly in advance. Why the gaps are deliberate A planning

One of the most common questions candidates ask before officer selection isn't about the exercises themselves, it's about timing. Start too late and you arrive underprepared. Start too early, without a plan, and momentum fades long before assessment day. There's no single correct answer, since it depends on your starting point and how much time you can realistically commit each week, but there are useful principles that apply whether you're heading to OASC, AOSB, or AIB. Why

The aptitude test is the part of OASC most candidates worry about first, and for good reason. Unlike the interview or the planning exercise, where preparation is about developing judgement and communication, the aptitude test is a straightforward pass/fail cognitive filter. Fall below the required standard and the rest of your performance at OASC, however strong, won't carry you through. The good news is that unlike leadership potential, aptitude test performance responds dir

STAR, Situation, Task, Action, Result, is the standard framework for answering competency-based interview questions at OASC, AOSB, and AIB, and most candidates preparing for officer selection have heard of it by the time they walk into the room. Fewer candidates use it well. The most common failure isn't forgetting the framework, it's spending so long on the Situation and Task that the Action and Result, the two parts that actually answer the question, get rushed, cut short,

Group planning exercises show up in one form or another at AIB, OASC, and AOSB, and they're some of the most revealing tasks on the day. Put six or seven strangers in a room, give them a problem and a deadline, and watch what happens. Some candidates freeze. Some talk over everyone else. A small number find a way to guide the group without dominating it, and those are the ones assessors remember. Leadership in these exercises isn't about having the best plan in your head. It'

Most candidates who fail officer selection boards don't lack ability. They make preventable mistakes during preparation or on assessment day that undermine otherwise strong performance. This guide covers the ten most common mistakes I see in coaching sessions and explains how to avoid them. 1. Spending All Your Time Planning, None on Presentation The Mistake: Candidates receive a planning exercise scenario with 30 minutes to analyse and build a plan. Most spend 28 minutes per

The interview is a critical component of officer selection at OASC, AOSB, and AIB. Most candidates know they'll face questions about leadership, failure, and motivation. What they don't know is how to answer these questions in a way that demonstrates genuine self-awareness rather than rehearsed responses. This guide covers the most common interview questions at military officer selection boards and explains what strong answers look like. Why Interview Questions Feel Difficult

How to Answer "What's Your Biggest Weakness" at OASC, AOSB, and AIB Interviews "What's your biggest weakness?" is one of the most common interview questions at OASC, AOSB, and AIB. It's also one of the easiest to get wrong. Most candidates either deflect with fake weaknesses ("I'm a perfectionist") or admit to something so concerning it raises red flags about their suitability for officer roles. This guide breaks down why the question is asked, what strong answers look like,

Planning exercises are a core component of officer assessment boards across all three UK armed forces. Whether you're attending the RAF's Officer and Aircrew Selection Centre (OASC), the Army Officer Selection Board (AOSB), or the Admiralty Interview Board (AIB), you'll face a planning exercise that tests your ability to analyse scenarios, make decisions under pressure, and present solutions clearly. Most candidates fail planning exercises not because they lack intelligence,

Group discussions at OASC, AOSB, and AIB rarely go perfectly. Within minutes, candidates get stuck debating minor details, lose track of time, or circle the same point without making progress toward a decision. Most candidates think the solution is either to take charge and start delegating, or to stay quiet and hope someone else fixes it. Both approaches lose you marks. Here's what assessors are actually watching for: who notices when things go wrong and helps the group reco
