What the route involves
There is a difference between wanting to join, being eligible to apply, completing a recruitment assessment and being ready for initial or specialist training. Each stage matters. The overview below is independent explanatory guidance; the Armed Forces make the decisions and may change the sequence.
Research and eligibility
Check the official entry criteria and speak with your Armed Forces Careers Office.
Application and selection interview
Follow the official recruitment process, including relevant assessments and security checks.
Pre-Joining Fitness Assessment (PJFA)
Review the current test format and establish a suitable training baseline.
Candidate Preparation Course (CPC)
Prepare for the official course and its fitness, swimming and other requirements.
Recruit Orientation Phase
Follow joining instructions provided by the service; avoid relying on unofficial dates or formats.
What preparation should cover
Good preparation starts with manageable consistency. Different military pathways emphasise different things, but a strong foundation generally involves appropriate aerobic development, progressive strength work, recovery and understanding the demands of your actual route.
- Aerobic capacity
- Bodyweight strength endurance
- Swimming familiarity
- Recovery and training consistency
Recruitment stages and requirements may change. Your recruiter and the Royal Navy website are authoritative.
