MODE OF SELECTION :
The Commission will prepare the category-wise Merit List and hand it over to India Meteorological Department, which would declare the final result.
SSC SCIENTIFIC ASSISTANT 2017 EXAM PATTERN
SC, ST, OBC and PH candidates, who are selected on their own merit without relaxed standards, along with candidates belonging to other communities, will not be adjusted against the reserved share of vacancies. Such SC, ST, OBC and PH candidates will be accommodated against the general/unreserved vacancies in
the post as per their position in the overall Merit List or vacancies earmarked for their category, whichever is advantageous to them. The reserved vacancies will be filled up separately from amongst the eligible SCs, STs, OBCs and PH candidates.
SSC SCIENTIFIC ASSISTANT 2017 EXAM PATTERN
A person with physical disability (OH) who qualifies the Commission ?s examination under General standards can be appointed against an unreserved vacancy provided the post is identified suitable for person with disability of relevant category.
Reserved category candidate who qualifies on the basis of relaxed standards viz. age limit, experience or qualifications, permitted number of chances in written examination, extended zone of consideration, etc. will be counted against reserved vacancies and not against general vacancies subject to fitness of such candidate for selection. Such candidates may also be recommended at the relaxed standards to fill up the number of vacancies reserved for them, irrespective of their rank in the order of merit. In so far as cases of Ex-Serviceman are concerned, deduction from the age of Ex-Servicemen is permissible and such exemption will not be termed as relaxed standards in regard to age.
SSC SCIENTIFIC ASSISTANT 2017 EXAM PATTERN
Success in the examination confers no right of appointment unless Government is satisfied after such enquiry as may be considered necessary that the candidate is suitable in all respects for appointment to the service/post.
Candidates applying for the examination should ensure that they fulfill all the eligibility conditions for admission to the examination. Their admission at all stages of the examination will be purely provisional, subject to their satisfying the prescribed eligibility conditions. If, on verification, at any time before or after the written examination, it is found that they do not fulfill any of the eligibility conditions, their candidature for the examination will be cancelled by the Commission.
