It's Clemente Community Academy in the Humboldt Park neighborhood. It will be one of 13 schools around the city to offer the program.
A study by the University of Chicago shows that students enrolled in International Baccalaureate are much more likely to attend and stay in college.
"IB encourages students to become active, compassionate learners with an understanding of the world around them," said Chicago Board of Education's Jesse Ruiz. "And we're excited to build on the success and expand this opportunity to all incoming students at Clemente."
Chicago school officials say they will soon announce two more schools that will adopt the program.
