The department boasts of a State-of-art Language Laboratory which is the pride of CEMK.

Apart from IIT KGP, CEMK was the first college to set up such a laboratory in West Bengal in the year 1999.

The syllabus for the MAKAUT prescribed language laboratory papers were framed by the present HOD of the dept.

Through innovative audio-visual and communicative based methods English Language is taught to the students of CEMK from B.Tech 1^st year to 4^th year.
