As per NEP 2020, teaching up to at least which grade is to be in the mother tongue or regional language?

NEP 2020 recommends that the medium of instruction be the mother tongue or regional language at least up to Grade 5, and preferably up to Grade 8 and beyond.

Grade 3 stops short of the minimum the policy states.

Grade 8 is the preferred extended limit, not the stated minimum.

Grade 10 goes beyond the minimum floor set by the policy.

This rests on evidence that young children grasp concepts best in their home language.

The policy also promotes Indian languages through the flexible three-language formula.
