About Grayslake Community High School District 127
Grayslake Community High School District 127 receives students from ten public and private sender schools spread across seven communities and five townships. The district names Grayslake, Palombi, Millburn, Woodland, and Fremont among the sending systems or schools, while its own boundary divides ninth-grade enrollment between Grayslake Central and Grayslake North.
Current freshman-testing materials make the transition groups more concrete. Grayslake Central prepares incoming students from District 46, Fremont Middle School, Woodland Middle School, St. Gilbert, and Prairie Crossing Charter School; Grayslake North separately schedules placement testing with Millburn. Those lists describe current incoming groups, not permanent feeder entitlements. Both high schools have Grayslake addresses, and the District 127 property boundary remains the final authority for Central or North.
