Prior to 1995, Itasca's School District 10 had one PreK-5 elementary school on each side of town: Franzen School on the North Side and Washington School on the South Side. (Upon entering 6th grade, all students attend Peacock Jr. High on the town's North Side. Itasca is served by High School District 108, Lake Park High School in nearby Roselle.)
Beginning with the 1995-1996 school year, the elementary schools were consolidated: Washington would become PreK-2nd Grade; Franzen would become 3-5.
St. Peter the Apostle Church and School has offered elementary education in Itasca since the 1960s.
There are only four railroad crossings in Itasca, from west to east: IL 53/Rohlwing Road, Catalpa Street, Walnut Street, and CR 10/Prospect Avenue.
Walnut Street between Bloomingdale Road and Division Street is generally regarded as Itasca's "downtown", boasting a convenience store, dry cleaners, Italian restaurant, bakery, train station, Starbucks, and the town's landmarks Itasca Baptist Church and Usher Park. Irving Park Road between Interstate 290 and First Street is also a commercial corridor, as well as the home of the town's Municipal Campus (library, museum, pool, fire station, and police station/village hall). West of I-290, Irving Park Road remains commercial, but with more national chain businesses (Holiday Inn, McDonald's, etc.). The Itasca Post Office is also on this stretch.
