Celebrating a Historic Milestone: Country Day World School is an Official IB World School

We are honored to officially share a historic moment for our community: Country Day World School is now an authorized International Baccalaureate (IB) World School! Achieving authorization is a famously rigorous process, but our dedicated team earned this status in just one year—a testament to the excellence of our staff and the strength of our vision.

A Seamless Partnership of IB and Montessori

The IB philosophy aligns seamlessly with our mission to nurture, inspire, and prepare children to flourish globally. By combining the hands-on, student-led environment of Montessori pedagogy with the IB framework, we empower students to become critical thinkers and compassionate leaders. The IB Learner Profile naturally reinforces our values of integrity, resilience, and social responsibility.

Empowering Middle Schoolers with the MYP

As an authorized school for the IB Middle Years Programme (MYP), we offer students aged 11 to 16 a concept-based curriculum that connects academic disciplines to real-world contexts. MYP students build essential creative thinking, reflection, and community action skills. All of our 6th through 8th graders participate in this transformative program, bridging the transition to high school and beyond.

Nurturing Lifelong Curiosity in Early Learners

Our commitment to global education extends to our youngest learners as well. Country Day World School is actively pursuing authorization as a candidate school for the IB Primary Years Programme (PYP).* Tailored for children aged 3 to 12, the PYP focuses on inquiry-based learning, nurturing natural curiosity and collaboration alongside our foundational Montessori methods.

Honoring Our Historic First IB Cohort

This milestone holds extraordinary meaning for our current 8th graders, the Class of 2026, who will have the distinct honor of being our very first cohort to graduate as official IB students. We could not be prouder of their hard work and leadership as they embark on this exciting new chapter.
