Hello,

One can join OTA through several ways:

• CDS exam: Candidates can qualify CDS exam and join OTA. CDS is held twice in a year
• SSC Tech: Technical graduate candidates can join OTA by SSC Tech entries.
• NCC: Graduate candidates with 50% marks and with 'B' or 'C' NCC certificate are also eligible for the service.
• Graduates in law with minimum 55% marks in law degree are also eligible.

So, candidates can join OTA through these ways.

Hope it helps.

All The Best!!
