The delegation, headed by the Leader of the Opposition in the Delhi Assembly, Vijender Gupta, submitted a memorandum on this to Baijal.
The Lt Governor "agreed in principal" to the MLAs' demand, Gupta said.
A large number of guest teachers have been working in Delhi's municipal corporation and government schools for many years, he said. And while they met all the other eligibility criteria, many could not apply for permanent jobs because they were over-age, Gupta added.
Age relaxations have been granted in similar circumstances in the past, too, he said. The Delhi Subordinate Services Selection Board in 2013 allowed an age relaxation for the post of special education teachers, Gupta said.
Applicants who had been working as resource persons for children with special needs in Sarv Shiksha Abhiyan were given an age relaxation, he added.
MLAs OP Sharma and Manjinder Singh Sirsa were present at the meeting with Baijal.
