To curb unfair practices using hi-tech gadgets, Central Board of Secondary Education, CBSE, is planning to buy eight thousand metal detectors to frisk candidates appearing for professional examinations conducted by it. According to a tender notice issued by the Board, to curb any unfair use of electronic devices, candidates will be frisked before entering the examination centre for detection of devices by use of highly sensitive hand-held bug and metal detectors. CBSE conducts professional exams like JEE (Main), AIPMT, UGC-NET. Earlier, the AIPMT exam for 2015 had been cancelled and held again after complaints of large-scale prevalence of unfair practices.
