Training is the key element for the professionalism of any Army. The Nepali Army is no exception. The Nepali Army has always given utmost priority to providing its personnel with adequate training. Following the famous saying of King Prithivi Narayan Shah, the Great, "The abilities of the Soldiers need to be polished at all times", the Nepali Army has always emphasized and provided professional training to its Soldiers and Officers alike to keep the Nepali Army ever ready to meet the challenges that they may have to face. The Nepali Army also provides specialist and vocational training to its troops. The Nepali Army institutionalized modern training with the establishment of the Nepali Army School in Chhauni in 1953. Today, the NA has many specialized army-level academies and schools under the Directorate General of Military Training (DGMT). The main training establishments of the Nepali Army are listed below:

Apart from the above-mentioned training establishments, all units from independent Companies up to Divisions provide their personnel with professional training daily. The units go through a few months-long training cycle every year.

The Nepali Army has a policy that requires each rank from a Private to a General to compulsorily undergo certain training for promotion to a higher rank. Apart from these mandatory trainings, there are various other specialized trainings that any Nepali Army personnel can optionally acquire. Nepali Army personnel who obtain distinguished results in training conducted in various training schools of the Nepali Army are also regularly sent to foreign countries to acquire advanced training. 

With the advances made in the military field, the Nepali Army has always sought to keep its personnel abreast with the latest development, both equipment-wise and conduct-wise. Similarly in continuing to maintain the unblemished image of the Nepali Army regarding Human Rights, trainings on Human Rights, Laws of Armed Conflict and International Humanitarian Laws are included in the course outlines of all Nepali Army trainings.
