Who We Are Chicago Public Schools (CPS) is the third largest school district in the United States, serving over 330,000 students in 600+ schools and employing over 40,000 people, most of them teachers. CPS has ambitious goals to ensure that every student, in every school and every neighborhood, has access to a world-class learning experience that prepares each for success in college, career and civic life. In order to fulfill this mission, we make three commitments to our students, their families and all Chicagoans: academic progress, financial stability and integrity. Five core principles are embedded within these commitments – high-quality, rigorous instruction, talented and empowered educators, safety and support, financial stability and collective impact.
