Indian Military Academy (IMA, Dehradun), Officers Training Academy (OTA Chennai & OTA Gaya), and National Defence Academy (NDA, Pune) are the prime Defence Institutes designated for training officers in India.
Although all these institutes aim to train Gentleman and Lady Cadets to become prospective officers of the Armed Forces, there are some subtle differences in the commissioning of the officers from IMA and OTA.

- For direct entry (DE), one needs to be between the age of 19 to 24 years (as on the first day of the month in which course is due to commence). The qualification required is a Graduate from a recognized University. The duration of the training is one and a half (1.5) years. One can apply for this entry through CDSE conducted by UPSC.
- The cutoff marks for IMA is generally higher than that for OTA in CDSE. This is because, for IMA, there are three papers (English, Maths, GK) which a candidate has to appear in whereas for OTA there are only two papers (GK and English).
