Army Line Officer Training (Cadetship)

Who we want

Officers are the leaders, decision makers and managers of the Defence Forces. A Line Officer leads, directs and motivates our frontline troops. The role comes with very real mental and physical challenges, with Officers being expected to lead from the front in all situations. Officer Cadets or trainee Officers engage in 15 months training in the Military College covering many basic and practical soldier skills and military fields of study before taking up an operational appointment in the Permanent Defence Forces. The Defence Forces is looking for people who have the potential to:

  • Plan, prioritize and organise
  • Analyse problems, in order to generate appropriate solutions
  • Be clear, concise and with effective communication skills
  • The ability to motivate others and work with a team.

Can you do all of this while working in a high pressure, mentally and physically demanding and environment?

After completing Officer training, cadets are commissioned into a Service Corp — Infantry, Artillery, Cavalry, Supply & Transport or Communications Information Systems.

As a young Officer many more opportunities for development, growth, variety and responsibility will come your way.


Age Limitations

Be 18 years of age or over and under 26 years of age on the date mentioned in the notice for the current competition.


The Cadet Competition is held annually and is the only way for potential candidates to join the Defence Forces to become an Army Line Officer. Candidates undergo psychometric and fitness testing, an interview and a medical exam.

Candidates who are invited to interview will be required to complete and sign a Garda Vetting Application Form that, pursuant to Section 8 of the Data Protection Act, 1988, will authorise the Garda Síochána to furnish to the Defence Forces either, a statement that there are no convictions recorded against a candidate, or a statement of convictions, as the case may be. 

The Induction Process will determine if you have the potential to lead troops as an Army Line Officer.


The purpose of cadet training is to develop character and leadership skills and instil a sense of duty and responsibility in the cadet. To benefit from that training, which is conducted in an environment of strict discipline, the cadet needs mental acuity and physical agility. During 15 months of training an Army Cadet masters basic military skills, such as rifle marksmanship, as well as developing the leadership skills required of an Army Officer. On commissioning the new Officer takes up a leadership position in one of the Army Corps.
