Almost all the engineering colleges are Approved by AICTE and Affiliated by Anna University. Apart from Approval and Affiliation, Accreditation also more important (but not necessary) for Engineering Colleges.
Even, the Accreditation is given by many authorities, AICTE’s NBA Accreditation and UGC’s NAAC Accreditation are used by Engineering Colleges.
These Accreditation are awarded based on the more than sufficient Colleges’ Infrastructures, Student Faculty Ratio, Faculties Qualifications, and many College Activities.
Note : For Approval and Affiliation all the above listed are required with some limitations. But, for Accreditation the entire above are required more than sufficient.
Tamilnadu Government also encouraging the Accredited Courses. As per current fee structure, TN Government allowed the colleges to collect the Tuition Fee Rs.40,000/- for Non Accredited Courses and Rs.45,000/- for Accredited Courses to the Government Allotted Seats. So, the TN Govt also consider the Accreditation as a good qualification.
In Tamil Nadu, Most of the Colleges are preferred to NBA Accreditation. Because the AICTE is the only authority for Controlling Approval for the Engineering Colleges and the NBA is also awarded by the same AICTE.
But now after the Supreme Court Order, UGC also come into the frame. So, the engineering colleges are now moving to get NAAC Accreditation thru UGC.
In NBA, the Course will be mentioned only as Accredited. And the Accreditation is based on courses and not for entire college. For example. If a college have 10 Courses and one Course only got NBA Accreditation means the other 9 courses are not having that much sufficient requirements. But the college can advertise as NBA Accredited College.
But in NAAC Accreditation, the Colleges’ Quality also mentioned in the Accreditation status as Grade. So it will very useful to understand the Colleges’ Quality.
As per sources, As of now, in Tamil nadu 21 Engineering Colleges (Not included Universities) are get NAAC Accreditation.
List of the 21 Colleges is available at UGC NAAC Accredited Engineering Colleges in Tamil nadu
