Changes in Portsmouth's Enrollment 1923--Present
Over the course of almost 90 years, the enrollment figures used to determine what classification a school was placed have changed quite often. The OHSAA started its state tournament with 2 classes in 1923, and it stayed that way until 1970, when 3 classes were introduced. The 3 class system lasted until 1988, when the decision was made to have a 4 division state tournament. Portsmouth High School's enrollment has changed quite drastically over the last 40 years. 1978 marked the first year for the Trojans in Class AA, which was the middle of the 3 class system.
