If you are interested for B.tech programme then after completing ITI course you need to go for Diploma courses which are offered by state level polytechnic colleges. After Diploma you are also eligible to get admission in IITs through JEE Advanced after qualify JEE Main Entrance Exam. There are many other colleges conducted its own Entrance Exam for B.tech Lateral Entry programme (Direct 2nd Year) admission.
Good Luck!
