Lateral Entry Scheme is intended to admit meritorious Diploma holders to the Second Year/Third Semester of the B.Tech courses to acquire a Degree in Engineering. Lateral Entry Scheme is approved by Government of Kerala as per G.O (Ms) No.156/2002/H.Edn dated 13.11.2002 for 10% of the sanctioned seats in addition to total seats. In order to maintain uniformity among various schemes of Diploma holders, AICTE has suggested a state level Entrance Examination for the selection. The list of various Engineering Institutions, the courses/ branches offered and the number of seats available in each branch will be published in the website - www.dtekerala.gov.in.
For English, out of the 10 marks to be awarded, 5 marks will be for questions based on a given passage and remaining 5 marks for basic Grammar and General English of +2 Standard.
