CDSE stands for COMBINED DEFENCE SERVICE EXAM.
It is a combined exam for joining three parts of armed forces i.e. the Indian Army, Indian Navy and Indian Air Force. It is similar to National Defence Academy (NDA) Exam & it is also conducted twice in a year similar to NDA. The difference is that NDA is conducted by upsc after 12th and cds is conducted after graduation. Final year graduation students can also apply for it but they have to produce the degree till a prefixed date, which is different for different training academies.
After passing cds written exam, candidates are called for SSB interview. Recommended & medically fit candidates join the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA) and Officers’ Training Academy (OTA) for training. Candidates selected for PC (permanent commission) join IMA, INA & AFA whereas short service commission candidates join OTA.
Candidates selected for permanent commission will undergo training for approx. 18 months. And candidates selected for short service commission will be trained at OTA for approx.11 months.
