In 2008, a small group of educators within CPS came together to advocate for the growth of computer science education in Chicago. What began as the very first Computer Science 4 All (CS4All) movement in the nation has grown into a full-fledged Office of Computer Science (OCS) at CPS. As OCS has grown, CPS has emerged as a national leader in Computer Science education, partnering with innovators in Los Angeles to adopt its paradigm-shifting curriculum Exploring Computer Science to ensure that students who graduate into a digital world can thrive there. As of 2019, we've trained 1,000 new teachers and put computer science in over 300 schools. We believe that from the moment a student steps into Kindergarten, until they fulfill the nation's very first high school computer science graduation requirement, our students should receive preparation to shape the world's technology. From its inception, OCS has made equity a core piece of our department's mission. Through our efforts to support communities which have historically been underrepresented in the field of computer science, we're working to make sure that computer science education in Chicago is a place that propels all of our students toward success.
