Consider the following statements regarding the school education restructuring framework under India's National Education Policy (NEP) 2020:

Statements

1. The NEP 2020 proposes a 5+3+3+4 curricular and pedagogical restructuring that replaces the earlier 10+2 structure at the school level, with the final four-year stage covering Classes 9 to 12.
2. The Kasturba Gandhi Balika Vidyalayas (KGBVs) operate on an integrated school model that extends up to Class 12, and evidence from such schools suggests lower secondary-stage dropout rates compared to schools that terminate at Class 10.
3. Under NEP 2020, the foundational stage of the 5+3+3+4 structure corresponds to the age group of 8–13 years, covering pre-primary through Class 2.
