At what age range does Key Stage 2 occur in the UK educational system?

Key Stage 2 in the UK educational system occurs for children aged 7 to 11 years. This stage encompasses the years of primary education from Year 3 through Year 6. During Key Stage 2, students build on the foundational skills acquired in Key Stage 1 and are introduced to more complex subjects and concepts. The curriculum covers a range of subjects including English, Mathematics, Science, and other foundation subjects, focusing on developing literacy and numeracy skills, critical thinking, and social development. This stage is crucial in preparing children for the transition to secondary education that follows in Key Stage 3.
