The Defense Services Command and Staff College (DSCSC) in Sri Lanka is an institution that provides advanced training to middle-grade military officers from the Sri Lankan Army, Navy, and Air Force, as well as individuals from the public sector. The College set out to train officers in command and staff techniques, but just as important, it aims at helping them to develop the intellectual attributes to cope with their future appointments and the challenges that are inevitable in the years ahead. By this process, seek to develop their breadth of understanding and the ability to analyse and evaluate issues in a logical way. One of the distinctions the DSCSC offers to high-achieving students is the award of the psc (Passed Staff College) title. This title signifies that the officer has successfully completed the staff college program and has demonstrated proficiency in staff duties and responsibilities. Additionally, for those officers who excel in their studies at the DSCSC, there is the opportunity to be awarded a Master of Science (MSc) degree in Defence and Strategic Studies.
