Reserve Officer Application Process

Becoming an Army Reservist - what happens when you apply?

Joining Steps: Reserve Officer

  • Stage 1Starting the progress

    The first step is to apply online to become a Reservist Officer.

  • Stage 2Meet your unit

    Now that you've applied, you'll be given a Candidate Support Manager. You can also follow your progress online. You'll normally be invited to meet your chosen unit and find out more, while giving the team a chance to see if you are a good fit. The team will tell you about the different roles that are available. During your meeting the team will help you plan what you need to do to go on to the next stage.

  • Stage 3Medical checks

    You'll need to provide information about your medical background, which will be checked. As part of this we will need access to your Primary Health Care Record (PHCR).

  • Stage 4Medical Assessment

    Once your medical history has been checked, you'll then be invited to an assessment centre for a face to face medical. Here you will meet a doctor who will make sure that you're medically fit to proceed with your application.

  • Stage 5Army Officer Selection Board (AOSB)

    Next, you'll be invited to Westbury for the AOSB Briefing - a 24 hour session to assess your officer potential, and to teach you the skills you'll need to pass the Main Board.

    Pass the Briefing, and you'll be asked back to Westbury for the Main Board, where you'll be tested mentally and physically over 3 1/2 days.

    Once you've passed AOSB, you're ready to start your training. We'll still need to run some background checks on you, but these are nothing to worry about.*
