What is OIR? This is the first test in the SSB Procedure where the intelligence level of a candidate is tested. On the basis of Officer Intelligence Rating (OIR Test),the Assessors will rate each and every candidates and it may even affect your chances of getting recommended even if you get screened in. Even if you are not able to complete or perform well inOfficer Intelligence Rating (OIR Test) there is nothing to worry as you still have chances of getting recommended if you perform well in PPDT. OIR further helps to decide and finalise your predictive value for selection. Again it spells your trainability level as the formula of trainability is IQ+period of time taken= your trainability level. Finally it decides your OIR. OIR stands for Officer's Intelligence Rating or Overall Intelligence Rating.
