That's according to a DuPage Policy Journal analysis of 2022 test score data compiled by the Illinois State Board of Education (ISBE).
ISBE reports that last year, 53.1 percent of DuPage County's 11,301 public high school students failed the Math portion of the Scholastic Aptitude Test (SAT) and have “minimal (or) incomplete… understanding of the knowledge and skills relative to Illinois Learning Standards.”
Students can achieve four proficiencies in their subjects (partially met, approaching, meets, and exceeds standards). This report concludes students who partially met or approached the standards have failed in the subject.
Addison Trail High School (80.7 percent), Fenton High School (80.7 percent), and Community High School (79.4 percent) had the highest failure rates in DuPage County. Neuqua Valley High School (30.9 percent) and Hinsdale Central High School (26.6 percent) had the lowest.
Of 23 DuPage County high schools, only 10 schools -- Wheaton North High School, Glenbard West High School, York Community High School, Waubonsie Valley High School, Metea Valley High School, Downers Grove North High School, Naperville North High School, Naperville Central High School, Neuqua Valley High School, and Hinsdale Central High School had passing rates of more than 50 percent.
County-wide, Math test failure rates rose from 46.3 percent in 2019 to 53.1 percent in 2022.
The failure rate increased at 23 DuPage County high schools in 2022, with the most significant increase happening at Lake Park High School (65.3 percent).
Failure rates rose the most in Coles County (82.7 percent), Mercer County (83.5 percent), Pope County (89.8 percent), Union County (91.3 percent), and Henderson County (92.2 percent).
No DuPage County high schools saw Math scores improve between 2019 and 2022.
Statewide, 70 percent of Illinois students failed the 2022 state Math exam, up from 64 percent in 2019.
The SAT test is administered to Illinois high school sophomores “to fulfill the requirement that students take an assessment for college and career readiness in order to receive a regular high school diploma.”
