MRA was basically a country school until Madison grew into a wealthy suberb, where MRA grew in enrollment and eventually got really good in athletics and academics. Based on the current state of Madison. I don’t expect that to change.
Prep was always the major power as they were a high school before JA and had the best combination of academics and athletics for years. Academics are still going strong but athletics have been a problem due to the emergence of MRA and Hartfield.
JA was the school that used to attract most Madison/Ridgeland/North Jackson families before MRA. They didn’t get a high school until the 80s but they flourished in the small but growing north side market. Now that MRA and Jackson Prep are proven better schools in academics and athletics, JA is losing appeal in everywhere outside of Jackson proper, and the tuition is so high many families won’t be able to pay for it.
Hartfield is an interesting case because they will never be able to compete with Prep academically, but have consistently been matching them athletically. Prep added an elementary school to combat Hartfield in their recruiting efforts to compete at an earlier stage. If Prep can win the elementary school battle where athletics don’t matter as much, they won’t have to worry about appealing to middle schoolers who are going solely for sports.
