If your child is about to start school, you’ll hear the word LKG everywhere: at admission desks, on school websites and in parents’ WhatsApp groups. Many people use it every day without knowing what the letters actually mean. So here’s the simple answer. The LKG full form is Lower Kindergarten. It’s the first formal class in many Indian schools after nursery, and it’s where a small child begins to learn letters, numbers, rhymes and good habits in a gentle, play-based way.

In this guide, I’ll explain the meaning in plain words, the age at which children usually join, how LKG differs from nursery and UKG, what kids learn, and what parents should prepare before admission.
