Actually JKSSB conducted class 4th exam in the first quarter of this year. But there were few instructions from the JKSSB's end...

only those candidates who have minimum qualification of class 10th & maximum of class 12th Stand eligible for the post of class-iv. But in reality candidates holding qualification higher than the prescribed 12th standard also appeared in the examination.

So chances of getting selection in the class iv exam goes in favour of those who are actually eligible candidates (10th/12th).
