All three Maine Township High School District 207 schools have been recognized on The Washington Post's 2014 list of "America's Most Challenging High Schools."
It marks the first time in the district's history that all three schools have made one of the top high school lists at the same time, Superintendent Ken Wallace said in a news release.
"Maine West joining this list represents an important milestone and is evidence of a concerted effort by all West staff under Principal Dr. Audrey Haugan's direction to continue to improve the quality of Maine West High School," Wallace said.
To earn a spot on the list, the Post divided the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests given at a school each year by the number of seniors who graduated that year. Any result of 1.0 or higher earns a spot on the list.
Maine East had an index this year of 2.348, Maine South had 1.693, and Maine West had 1.565.
