If you are recruiting withnthe approval of the apprantic advisor, then you need to pay a minimum of what he says. However, if you are recruiting directly, then the stipend must be higher than minimum wages.
You can have stipend provided at a lower rate in the standing orders, and define them specifically as apprentices under standing orders. However, in case of a complain, you will have a tough and expensive fight on hand. Is it worth doing that for saving ₹1500-2000 per month ?
And yes, I hope you are within the limits of number of apprantice approved for your comoany by the apprantice advisor
