Engineering Knowledge test [EKT] paper was for the first time introduced in 2014-2 AFCAT exam.
EKT 1 2015 was conducted along with AFCAT 1 2015 on 22/2/2015.
EKT Exam 2015 was conducted on 13 September 2015 along with AFCAT exam, candidates who have opted for Indian Air Force technical branch have attended the EKT exam 2015 just after the AFCAT exam.
