New Delhi : The four-year undergraduate programme introduced by Delhi University in its colleges may come in the way of recognition of School of Open Learning courses. The accreditation of the 10 courses at SOL by Distance Education Council—now the Distance Education Bureau (DEB) ,is expiring on June 14. According to SOL sources, the degrees offered in the classroom and distance learning methods by a dual-mode university should be in sync but the existing DEB guidelines Hence, while DU's undergraduate honours degree is now of four years duration and in semester mode, SOL courses are still of three years duration and in annual mode. According to SOL officials, there needs to be a major revamp of the courses to make them in sync with the DU's undergraduate degree. Besides, in case the recognition is not given on time, students may suffer. Three years ago, SOL students had to move the high court to get relief after their degree was not accepted by prospective employers. The issue was resolved and DEC gave recognition to the courses for two years—2012-14. ‘Admissions for the new session are drawing near and the university should intervene in the matter. The issue of recognition may affect admissions. Moreover, it's time the university extends the reforms to SOL in order to follow the distance education guidelines. The SOL students are bound to suffer otherwise,’ said a SOL official. SOL is the country's first distance education institute started by the Government of India as a pilot project. It has become a source of income for the university. DU cannot afford to be slack as SOL generates close to Rs 70 crores in revenue.
