Hi Sachin,
Diploma is a 3 year duration course but having done your ITI. You can take admission directly in the second year of Diploma through Lateral Entry.
There are many Govt. and Private Colleges who offer diploma courses.
But Govt. Colleges have relatively less fees to pay than Private Colleges.
For example Diploma Course fees in Govt. College in Uttarakhand is approx. 18000 INR and it can be different for every state.
Every private college has their own fees structure which is different for each College.
But you can also get admission in various Govt. Colleges after clearing entrance examination test which are held by every state every year.
So you could get into top colleges of the state.
Thankyou.
