A decision to this effect was taken at a meeting of the Board of Technical Education chaired by Chief Minister Sheila Dikshit.
"The board has approved a proposal for exemption of tuition fee for persons with disability," Dikshit said after the meeting.
The board also decided to provide an extra opportunity to clear examinations to those disabled students who got admission in the polytechnics since 1999 onwards and could not clear all the papers in the stipulated period.
Such candidates will be eligible for the special examination subject to the condition that they have not availed the "mercy chance examination" held in March 2011, said an official.
