How Serving Soldiers Become Officers - ACC, PC(SL) & SCO Entry

The Indian Army recognises that leadership is often shaped on the ground, not just in academies. Serving soldiers who show potential are given exclusive opportunities to earn a commission through ACC, PC(SL), and SCO entries.

These service entries allow soldiers to rise from the ranks and serve as commissioned officers based on experience, merit, and leadership capability.

How the System Works (Quick Overview)

Term	Purpose	Role
SCO	Selection entry	Screens serving soldiers
ACC	Training pathway	Builds officer-level skills
PC (SL)	Commission type	Defines officer career tenure

ACC (Army Cadet College) Entry

The Army Cadet College (ACC) is a specialised wing of the Indian Military Academy (IMA), Dehradun, designed exclusively for serving Army personnel to become commissioned officers. This entry is not open to civilians.

ACC training is academically and militarily intensive, similar to NDA, with the major advantage that ACC cadets already understand soldier life, which helps them lead effectively as officers.
