Interstate Athletic Conference

The Interstate Athletic Conference is an all-boys high school sports league made up of six private high schools in the Washington, D.C., area, competing in twelve varsity sports: baseball, basketball, cross country, football, golf, ice hockey, lacrosse, soccer, swimming and diving, tennis, track and field, and wrestling. The IAC is widely regarded as one of the most competitive and talent-deep lacrosse leagues in the nation. Some schools in the IAC are co-ed, so they do not have as many boys to participate in athletics as some schools in the MAC and WCAC. For example, Gonzaga College High School (WCAC), have over 900 boys enrolled at the school while Episcopal High School (IAC) only has 435 boys and girls combined. Although this is true, the IAC is seen as on par with or surpassing the WCAC and the MAC and more competitive than the PVAC, the other private high school sports conferences in the Washington, D.C. area. The IAC is also known for its academics as it boasts 3 of the most elite boarding schools in the country.
