These institutes’ function is to prepare a technical vocational force in specializations that do not require scientific depth e.g. carpentry, ironwork, tailoring, cooking etc. The student who does not wish, for any reason, to pursue school education may leave it after completing his 24th course and join these institutes to study one such specialisation.

Experts determine the study period for each of these options, as well as the subject nature that the student studies and required skills to perfect these vocations. Upon success in these institutes, the student is awarded a certificate known as a “Vocational Certificate” in carpentry, ironwork, tailoring, etc.
