The **NDA **exam is conducted by **UPSC **for admission to the Army, Navy and Air Force wings of the **NDA**. This exam is a gateway for candidates looking forward to joining Defense Forces including Army, Navy and Air Force.

This is a national level exam conducted twice a year: **NDA I** and **NDA II** to help candidates make a career in Defense services. **NDA **Exam 2019 schedules for **NDA I** and **NDA II** exam has already been released by **UPSC**.

National Defense Academy & Naval Academy Examination will be a two-step process where candidates first need to take the exam and then qualify the **SSB **interview conducted by the Service Selection Board.

National Defence Academy & Naval Academy Examination (I) and (II) shall be conducted according to the following plan:

The subjects of the written examination under Part-I, the maximum marks allotted to each subject/paper, the time allowed and for Part-II shall be as follows:

Subject | Code | Duration | Maximum Marks |

Part II - SSB Test/Interview | 900 |

- The papers in all the subjects will consist of objective type questions only. The question papers (test booklets) of Mathematics and Part 'B' of General Ability Test will be set bilingually in Hindi as well as English
- In the question papers, wherever necessary, questions involving the metric system of Weights and Measures only will be set
- Candidates must write the papers in their own hand. In no circumstances will they be allowed the help of a scribe to write answers for them
- The Commission has the discretion to fix qualifying marks in any or all the subjects at the examination The candidates are not permitted to use the calculator or Mathematical or logarithmic table for answering objective type papers (test booklets). They should not, therefore, bring the same inside the examination hall

The SSB procedure consists of two stage Selection process - stage I and stage II. Only those candidates who clear the stage I are permitted to appear for stage II. The details are :

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

(b) Stage II Comprises of Interview, 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 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 are 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 test. In addition, marks for Conference are also allotted based on the initial performance of the Candidate in the three techniques and 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 SSB
