NDA stands for National Defence Academy — the tri-service training academy at Khadakwasla, Pune, where selected cadets of the Indian Army, Navy and Air Force begin their officer training after clearing the UPSC NDA/NA examination.
The NDA exam is a national-level entrance test conducted by UPSC for admission to the National Defence Academy and the Naval Academy. It is held twice a year and consists of a written examination followed by the SSB interview. The syllabus is based on the Class 12 level.
The National Defence Academy exam, also written as the NDA/NA examination, is conducted by UPSC for candidates who want to join the Indian Armed Forces as officers. It is the standard officer-entry route for the Army, Navy and Air Force after Class 12.
It is the same UPSC NDA/NA examination. The term is commonly searched in both British and American spellings, but the official name used in India is National Defence Academy. The syllabus is based on the 10+2 level.
The NDA NA exam is the UPSC National Defence Academy and Naval Academy Examination — a single test that covers entry to both the NDA and the Indian Naval Academy.
UPSC NDA refers to the NDA examination conducted by the Union Public Service Commission. UPSC releases the notification, accepts applications, conducts the written test and publishes the official result.
The UPSC NDA form is the online application released by UPSC for eligible candidates during the registration window. It is filled on the official portal: upsconline.nic.in.
The NDA result is the official list of candidates who qualify the written exam or the final selection process. UPSC publishes it after each cycle on upsc.gov.in and upsconline.nic.in.
