The nongraded school allows students of different ages to learn together.
Nongraded → It is formed from "non-" (meaning not) and "graded" (from the root "grade" which comes from Latin "gradus", meaning step or degree). The word "nongraded" means not assigned a grade or step in a ranking system.
Think of 'non-' meaning not, and 'graded' referring to steps or levels — so nongraded means something that does not have a step or level assigned.
