Course overview
ITI is the shortest formal route from Class 10 to a wage. One or two years, a national certificate, and a trade you can work in immediately - and unlike most of school, it is taught in a workshop by people who have done the job.
The choice that matters is the trade, not the institute. Trades differ enormously in what they pay, where the work is and how easily you can eventually work for yourself. Electrician and plumber travel anywhere and turn into your own contracting work. Welder and fitter sit with industry and pay best where industry is. COPA is office work rather than workshop work. Refrigeration is seasonal but has repeat customers built in.
Check NCVT or SCVT affiliation before you pay anything. An unaffiliated institute costs the same and leaves you with a certificate employers and apprenticeship schemes do not recognise. This is the single most expensive mistake in the sector.
No door closes. After a trade you can take an apprenticeship under NAPS, sit for railway and defence technical entries, or use lateral entry into the second year of a polytechnic diploma and continue from there.
