2 Illinois school districts land on list of nation's best

2 Illinois school districts ranked Top 10 in the U.S.

Two Illinois school districts landed on a new ranking of the United States' top education systems.

The ranking was conducted by online tutoring marketplace Wiingy using data from school rating and review site Niche.

Wiingy ranked U.S. school districts by analyzing 12 key factors. Each district's letter grades in nine categories—such as academics, college prep, and resources—were converted into scores on a 0–12 scale, with A+ equaling 12.

Math and reading proficiency rates and user review scores were also scaled to 12, then all values were averaged and indexed into a final score out of 10 to determine the rankings.
