The CDS 2027 eligibility criteria strictly require candidates to be unmarried citizens of India (or specified subjects of Nepal/Bhutan) aged 19–25 years, possessing a recognized Bachelor's degree. Male candidates can apply for all wings, while female candidates are exclusively eligible for the Officers' Training Academy (OTA) SSC non-technical courses.
What is the Exam?
The Combined Defence Services (CDS) examination is a prestigious national-level recruitment process conducted biannually by the Union Public Service Commission (UPSC). It serves as the gateway for commissioning officers into the Indian Armed Forces, including the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers' Training Academy (OTA). We at Exam Bhai believe this exam is the ultimate test of character, intellect, and physical endurance for future leaders of the nation.
