In order to maintain a uniform standard of graduate and post graduate teaching through-out the Country, the Government of India through its notification in 1988 stated that only those candidates would be considered eligible for a post of lecturer, who besides fulfilling the minimum academic qualifications for it, also qualify in a comprehensive test, National Eligibility Test (NET), to be conducted for the purpose.
Accordingly, the University Grants Commission (UGC) has been conducting the eligibility Test (NET) for lecturership on Humanities and Social Science subjects. The Council of Scientific and Industrial Research (CSIR) has been conducting the eligibility test (NET) for lecturership in the Science subjects.
UGC simultaneously asked the Govt. of the States and Union Territories about their option to conduct their own test or alternatively adopt the UGC-CSIR test. In case they opt to conduct a test equivalent to UGC-CSIR then these should be accredited by the UGC. In response to this, many States opted to conduct their own test i.e. State Level Eligibility Test (SLET) for lecturers. Kerala also constituted their own SLET.
