General overview of the CDS examination

The Union Public Service Commission (UPSC) administers the “Combined Defence Services” Examination (CDS Examination) twice a year to recruit candidates for the Indian Military Academy, Officers’ Training Academy, Indian Naval Academy, and Indian Air Force Academy. These institutions educate officers for the Indian military. 

The CDS test will be administered by the UPSC twice per year, once in February and once in September. Candidates who intend to serve their country by entering the armed forces can now begin the application procedure for the CDS examination. Before submitting an online application for the CDS examination, candidates must satisfy all of the qualifying requirements provided by the Commission. 

The candidates will be selected based on their performance on a written examination, which will be followed by an interview in which their intelligence and character will be assessed. The remaining candidates will be placed to the various academies according to their choices and overall merit.

The two stages of the CDS selection procedure are the written exam and the SSB interview. Before making the final selection, the performance of the applicants in both phases is considered. After completing training at the IMA, INA, AFA, and OTA, respectively, candidates are selected for the position of lieutenant. During their course, each candidate will receive an allowance of 56,100 INR.
