Hello!

In ITI courses,  you might be referring to “categories” or “trades” available in ITI institutes. ITIs offer skill-based training in different sectors such as Electrician, Fitter, Welder, Plumber, Computer Operator, Draughtsman, and Motor Mechanic. Some institutes also have non-technical trades like Sewing Technology, Fashion Design, and Office Assistant. The course duration generally ranges from 6 months to 2 years, depending on the trade you choose. Each category is designed to give practical skills so you can start working or even open your own business. Admission is usually based on merit or entrance exams, depending on the state. The best way is to check the official ITI prospectus of your region to know the exact categories offered.
