NDA Vs CDS, Difference Between NDA & CDS, Is CDS Higher Than NDA?

NDA Vs CDS: The National Defence Academy (NDA) and Combined Defence Services (CDS) exams are two of the most prestigious exams for joining the Indian Armed Forces. Conducted by the Union Public Service Commission (UPSC), these exams aim to select candidates for the Indian Army, Navy, and Air Force. 

Although both exams have the same goal of recruiting officers, they cater to different educational qualifications, age groups, and career aspirations. This guidepost will provide an in-depth analysis of NDA Vs CDS while addressing common queries including eligibility, selection process, training, and benefits, to help aspirants make an informed choice.

What is NDA?

The National Defence Academy (NDA) is the joint services academy of the Indian Armed Forces, where cadets of the Army, Navy, and Air Force are trained together before proceeding to their respective service academies for further pre-commission training. Established in 1954 in Khadakwasla, Pune, the NDA is a premier institution that provides a combination of academic, physical, and military training to young aspirants.

Candidates are selected for NDA through an entrance exam conducted by the Union Public Service Commission (UPSC) twice a year. The exam evaluates the candidate’s knowledge in Mathematics and General Ability, followed by the SSB interview, a strict selection process to test a candidate’s personality, leadership skills, and aptitude.

The CDS exam consists of three subjects: English, General Knowledge, and Elementary Mathematics (for IMA, INA, and AFA). For OTA, the Mathematics paper is excluded. After qualifying for the written exam, candidates must pass the SSB interview and medical tests to proceed to the training academies.
