In perhaps the worst results in two decades, 64.75 percent students have failed in class XII exams conducted by Bihar School Examination Board (BSEB), an Indian Express report has said. As per results declared on Tuesday, just 30.11 percent Science students and 37.11 percent Arts students have passed. Passing percentage was 73.76 for Commerce stream. The board had introduced stringent measures this year for fair examination and evaluation of students after the topper scam last year. The board has attributed this year\u2019s fall in pass percentage to these measures. Last year 67.1 percent had passed. Board chairman Anand Kishor has said that results should be taken in the right spirit as the way forward to ensure quality education. \u201cWe introduced bar coding to protect the identity of candidates during evaluation, besides ensuring fair examination,\u201d he was quoted as saying by Indian Express. State Education Minister Ashok Kumar Choudhary has conceded that these results were worst in almost two decades. BSEB had registered such results during the times of chief ministers Bindeshwari Dubey (1985-88) and Kedar Pandey (1972-1973), and in the mid-1990s. \u201cAs education minister, I am surely not happy with the result. But we are working in a positive direction to shrug off the tag that most Bihar students pass exams by using unfair means. After the toppers scam, we introduced a transparent system to ensure fair examination. Those who have passed are gold,\u201d Choudhary was quoted as saying by Indian Express. He further said that those failing exams. still have a chance to write compartmental examinations in five subjects. The toppers\u2019 scam had come into limelight after it was found that the science and arts toppers of last year were not able to answer simple questions. The then board chairman Lalkeshwar Prasad Singh was among those arrested for tampering with the evaluation process.
