An ITI (Industrial Training Institute) candidate can potentially join the second year of a diploma program through lateral entry.

The eligibility for lateral entry typically applies to diploma programs in a field related to the ITI trade you completed. For example, an ITI certificate in Fitter would have a better chance of qualifying for lateral entry into a diploma program in Mechanical Engineering compared to Civil Engineering.

Universities and institutes offering diploma programs have their own specific criteria for lateral entry admission. These criteria might include:

• Minimum marks obtained in the ITI final exam.
• Entrance exams conducted specifically for lateral entry students.
• Seats available for lateral entry in the second year.
