While NEP 2020 does not rigidly fix exact ages for each class, government directives and implementation guidelines recommend the following age ranges as a standardised framework:
| Stage / Class | Typical Age Range (approx.) | Notes |
|---|---|---|
| Nursery / Pre-school | ~3–4 years | Entry into foundational stage; generally recommended from 3 years. |
| Lower Kindergarten (LKG) | ~4–5 years | Follows Nursery; subject to school/board cut-offs. |
| Upper Kindergarten (UKG) | ~5–6 years | Final year of pre-primary before Class I. |
| Class I (Grade 1) | 6–7 years | Strongly recommended minimum age as per NEP; aligned with ECCE completion. |
Note: The key minimum age widely recommended by the Ministry of Education and state notifications is 6+ years for Class I admissions. This aligns with NEP 2020’s focus on developmental readiness and completion of preschool/ECCE before entering primary school.
