Lawrence Junior High is apparently a standard three-grade junior high school. Although the show lasted three seasons, the timeline of the show is only two school years, with Louis and his friends remaining in the 7th grade until some point after the middle of the second season. In several third-season episodes there are subtle references to an advance in the timeline that puts Ren and her friends in the 9th grade and Louis in the 8th grade. Ren finally graduates in "The Even Stevens Movie".
