From January 2027, Army officer selection will sit under the new Armed Forces Recruiting Service. It will be managed by SERCO, rather than Capita.
Briefing and Main Board continue in their current format until the end of 2026, so if your dates fall this year, everything on the platform matches what you will face. From 2027, the transition to the revamped tri-service selection process will begin.
While we have a very good idea of what the changes will entail, full details of the new process have not been published yet by either the British Army or SERCO. To avoid any confusion, we will refrain from speculating in public as to what the new changes will bring.
Once the changes are officially confirmed, Officer Ready will be updated to reflect them. Everyone with active access will receive those updates at no extra cost. This will include, if required, access to preparation tests for the Defence Aptitude Assessment.
We are in close contact with many of our existing users, some of whom we offer one-to-one support to, and will receive first-hand feedback of the new assessment. We will communicate this feedback to all Officer Ready users once we have verified it. We will also use it to update and improve our services, ensuring they are tailored to the new assessment process.
In the meantime, your preparation is not wasted. Officer selection has always tested the same things. Those are the skills Officer Ready builds, and they stay with you whatever the format.
Officer Ready is a training platform built specifically for British Army officer applicants. It was developed by Tom Moffat, a former British Army officer who has worked on officer selection and leadership development from four angles:
The platform is the product of that experience. It is tailored to Army officer selection and is grounded in the approach that the British Army uses to develop its own leaders.
Officer Ready is for anyone applying to become a British Army officer, whether you're going for direct entry, reserve entry, a professionally-qualified commission or an Army scholarship. Every route is assessed on the same skills, even where the formats differ in length. If you're attending selection in 2027, the platform will be updated for the new process as soon as its details are published.
The Countdown plan is for the final sprint. If you are attending Briefing or Main Board before the end of 2026, it gives you a focused, high-intensity month to sharpen your skills and test your readiness immediately before you attend.
The Complete plan is designed for the standard candidate journey. Bought now, 6 months of access carries you into 2027, and every update we make for the new selection process is included at no extra cost.
The Committed plan is for those taking a more strategic approach. Many successful candidates start preparing 9 to 12 months in advance. If you start now, you can spend the coming months building the skills that officer selection has always tested. We will add preparation for the new process once it is confirmed. You will then have plenty of time to work through it before you attend without the stress of a ticking clock.
Our performance analysis tool lets you compare your psychometric test scores with those of other Officer Ready users. Unlike other test platforms, our data is drawn exclusively from British Army officer candidates, so you get a highly accurate picture of where you stand in comparison with your peers.
Officer Ready works on both. It is a browser-based platform rather than a mobile app, so there is nothing to install and your progress follows you between devices. A laptop or desktop gives you the best experience, but every aspect of the platform, including the psychometric tests and the Workout Tracker, is compatible with mobile use.
We are confident that Officer Ready will make a genuine difference to your preparation for officer selection. However, if you change your mind within 7 days of purchase and have completed fewer than 10 sessions on the platform, we will give you a full refund.
