For decades, Concept Schools has set out to positively impact families across the Midwest. Our dedication to providing a high-quality, STEM-focused education has set students up for success in higher education and beyond. Here are some of the highlights from Concept’s award-winning work. 


CREDO Recognition

In 2023, the Center for Research on Education Outcomes (CREDO) from Stanford University recognized Concept as a gap-busting charter management organization for its ability to close achievement gaps. CREDO reported that charter schools associated with charter management organizations, like Concept Schools, outperform independently run charter schools.


Cognia Accreditation

Concept earned system-wide accreditation and network-wide STEM certification from Cognia, a nonprofit organization that provides quality assurance for schools, school districts, and education service providers. We are the largest charter network in the Midwest to receive this honor. 


"School accreditation as conferred by the Cognia Global Accreditation Commission provides Concept Schools with another nationally recognized mark of quality for our network," said Concept Schools President/CEO Sedat Duman. "It demonstrates to the communities we serve our commitment to excellence, our openness to external review and feedback, and our desire to be the best organization we can be."
