Illinois State Board of Education (ISBE) records show that 60.2 percent of Streamwood High School's (SHS) 2015 graduating class enrolled in college within 12 months of graduation.
The 2015 state average for students in public schools was 70 percent.
For SHS, its college enrollment rate marks an improvement over 2014, when 56.6 percent of its graduates chose post-secondary education.
Among other high schools in Kane County, the Class of 2015 college-enrollment rates at Geneva Community High School (78.0 percent), Batavia Senior High School (73.4 percent) and St. Charles North High School (71.8 percent) were all higher than that of SHS.

Enrollment at SHS in 2015 was 2,129; 461 (21.65 percent) were seniors.
ISBE said 29.9 percent of SHS seniors were "college ready" in 2015, vs. an average of 46 percent statewide.
All students who score a 21 or higher on the ACT qualify as "college ready."
SHS students did better in reading (23.4 percent) and English (43.4 percent), and worse in science (19.3) and math (22.4).
Only 9.6 percent of SHS students were college ready in all four subjects, ISBE said.
