Insignificant difference was found among the views of heads by age, qualification, experience as a chairperson, and total length of service in the present department regarding their role in the promotion of communication. Teachers were not differentiated by qualification, designation, age and experience in their views. It viis concluded that heads of teaching departments play positive role in the promotion of communication at postgraduate level.

For the development of language proficiency of the heads and teachers, a language laboratory may be established in every institution of higher education.
