Hi aspirant,

Diploma holders who want to get admission in B.tech courses will get admission to the second year of any B.Tech course through B.Tech lateral entry program. It is important to note that no national entrance test is conducted in the country for B.Tech lateral entry in government colleges, private colleges, universities, etc. The B.Tech lateral entry admission to various colleges is done on the basis of various state level lateral entry exams like AP ECET , TS ECET , UPSEE lateral entry, JELET , etc provided that candidates must have passed a Diploma in the relevant field with a minimum of 45% marks (40% for reserved category).  Following below I will provide you the link to get the list of all government colleges providing lateral entry:
