What Is the CDS Exam?
CDS stands for Combined Defence Services. It is a national entrance exam organised by UPSC — the Union Public Service Commission — twice every year. This exam is the official gateway for graduates who want to become officers in the Indian Armed Forces.
Candidates who clear the CDS written exam are then called for an SSB Interview — Services Selection Board — where their leadership ability, mental strength, and overall personality are carefully assessed by a panel of experts.
After clearing both stages successfully, selected candidates join one of these prestigious training academies:
- Indian Military Academy (IMA), Dehradun
For candidates who wish to serve in the Indian Army as commissioned officers. - Indian Naval Academy (INA), Ezhimala
For candidates who want to join the Indian Navy. - Air Force Academy (AFA), Hyderabad
For candidates aiming to serve as officers in the Indian Air Force. - Officers Training Academy (OTA), Chennai
Open to both men and women graduates for Short Service Commission.
