**TWO-STAGE SELECTION PROCEDURE FOR NDA**

Two-stage selection procedure based on Psychological Aptitude Test and Intelligence Test has been introduced at Selection Centres/Air Force Selection Boards/Naval Selection Boards. All the candidates will be put to stage-one test on the first day of reporting at Selection Centres/Air Force Selection Boards/Naval Selection Boards. Only those candidates who qualify at stage one will be admitted to the second stage/remaining tests. Those candidates who qualify for stage II will be required to submit the Original Certificates along with one photocopy each of: (i) Original Matriculation pass certificate or equivalent in support of date of birth, (ii) Original 10+2 pass certificate or equivalent in support of educational qualification.

Candidates who appear before the Services Selection Board and undergo the test there will do so at their own risk and will not be entitled to claim any compensation or other relief from the Government in respect of any injury which they may sustain in the course of or as a result of any of the tests given to them at the Services Selection Board whether due to the negligence of any person or otherwise. Parents or guardians of the candidates will be required to sign a certificate to this effect.

To be acceptable, candidates for the Army/Navy/Naval Academy and Air Force should secure the minimum qualifying marks separately in (i) Written examination as fixed by the Commission at their discretion and (ii) Officer Potentiality Test as fixed by the Services Selection Board at their discretion. Over and above candidates for the Air Force, and all the SSB qualified candidates as per their willingness, eligibility, and preference for flying branch of the Air Force, should separately qualify the CPSS.

Subject to these conditions the qualified candidates will then be placed in a single combined list on the basis of total marks secured by them in the Written Examination and the Services Selection Board Tests. The final allocation/selection for admission to the Army, Navy, and Air Force of the National Defence Academy and 10+2 Cadet Entry Scheme of the Indian Naval Academy will be made upto the number of vacancies available subject to eligibility, medical fitness, and merit-cum-preference of the candidates. The candidates who are eligible to be admitted to multiple Services/Courses will be considered for allocation/selection with reference to their order or preferences and in the event of their final allocation/ selection to one Service/Course, they will not be considered for admission to other remaining Services/Courses.

The SSB procedure for NDA consists of two stages of Selection processes – stage I and stage II. Only those candidates who clear stage I are permitted to appear for stage II. The details are:

(a) Stage I comprises Officer Intelligence Rating (OIR) tests are Picture Perception * Description Test (PP&DT). The candidates will be shortlisted based on the combination of performance in the OIR Test and PP&DT.

(b) Stage II Comprises Interviews, Group Testing Officer Tasks, Psychology Tests, and the Conference. These tests are conducted over 4 days. The details of these tests are given on the website http://joinindianarmy.nic.in/ The personality of a candidate is assessed by three different assessors viz. The Interviewing Officer (IO), Group Testing Officer (GTO), and the Psychologist. There is no separate weightage for each test. The mks are allotted by assessors only after taking into consideration the performance of the candidate holistically in all the tests. In addition, marks for the Conference are also allotted based on the initial performance of the Candidate in the three techniques and the decision of the Board. All these have equal weightage. The various tests of IO, GTO, and Psych are designed to bring out the presence/absence of Officer Like Qualities and their trainability in a candidate. Accordingly, candidates are Recommended or Not Recommended at the SS
