The Maui Interscholastic League or MIL Consists of 13 high schools that sponsor a number of athletic sports, including football, basketball, volleyball and soccer. Moloka'i High School and Lanai High School are voluntary members of the MIL due to the lack of other major high schools on the island of Moloka'i and Lanai.
