The World Bank's loan of Rs 2,234 crore for education in Bihar will be used to strengthen teacher-training colleges, set up colleges and take other measures to boost the quality of education in the state, education minister Ashok Choudhary said on Tuesday.

The bank announced last year it would offer the money over the next five years.

"The state government in past few years has increased infrastructure. Our next focus will be providing quality education to students," Choudhary said at a Unicef event to release a report, The State of the World's Children 2016.

Department sources said around 66,000 teachers will be trained and around 2 lakh teachers will be appointed to improve the teacher-student ratio in government schools, which has gone up from 1:78 in 2005-06 to 1: 56. There was one classroom for every 90 students in 2005-06, which has now gone up to a classroom per every 47 students.

The education department will also launch a three-month pre-school module for students before their entry to formal education (Class I).

Despite spending 15 per cent of the state budget, the education sector is rife with malpractices, scams and poor pass percentage.

"The government has recruited lakhs of teachers, but these teachers are not qualified to teach," said former Patna College principal N.K. Choudhary.

A government school teacher in Patna said: "There is no academic discipline. Students receive text books three to four months after their classes start."
