This Middle School Layout features three levels: primary, middle, and lower secondary. This Middle School Layout depicts the preliminary stage. The middle stage would include children in classes VI to VIII (11-14 age group) and children in classes I to V (6 – 11 age group). The lower secondary stage, comprising classes IX and X (14-16 age group), is the final stage of a ten-year general education program. Middle school is the time in a student's life after elementary school but before high school in the United States. Middle school grades are typically 6th, 7th, and 8th, though some districts include 9th grade in their middle school programs.
