AHMEDABAD: A class X student was marked 80 out of 50 marks in his Maths exam in the SSC boards, held earlier this year. This would have been perfect luck for the student, had the error not been too glaring.“The teacher who assessed the paper made the gross error of giving 80 marks out of 50 was shown the answer sheet. The student had scored only 8 marks,” said GSHSEB officer on special duty M M Pathan.The teacher concerned was one of 3,200 teachers who will be summoned by the Gujarat Secondary and Higher Secondary Education Board (GSHSEB) for making errors worth 10 marks or more while assessing SSC papers. In the HSC (science) exam, 657 teachers were found to have made errors worth 10 marks or more.These teachers are being summoned in batches and will be shown the gross errors they made which severely compromise the sanctity of the board exams, where every mark has the potential to alter the career paths of students, board officials said.In another gross mistake, two HSC (science) students were given 15 marks extra and another received 13 marks extra, due to mistakes in adding up marks. Shockingly, the mistake by the teacher was caught neither by the moderator or the coordinator who constitute the next two levels of paper checking.“It is a rare occurrence that mistakes in papers which were seen by both moderator and coordinator were not caught and rectified. This is a serious failure and the case has been highlighted to the teachers who are being called,” said exam secretary R H Junakiya said.
