The BCD Difference


We believe in a welcoming and inclusive community where students, family members, faculty, staff, and alumni work together to support and nurture students to be engaged, kind, resourceful, confident, empowered, well-rounded good citizens.

Engaging Curriculum

We believe children thrive when engaged, challenged, and surrounded by peers and teachers who love school. Our research-based curriculum is infused with innovative strategies to support differentiation, skill mastery, hands-on projects, and a love of learning.


We believe that academics are only one piece of school and that students need tools, support, and strategies to learn to problem solve, communicate, create resolutions, think critically, take risks, and fail forward.

Small Class Sizes

We believe small class sizes allow our teachers to truly see, know, and love each student. It is essential in differentiating instruction. Our Board of Trustees mandates that sizes not exceed 18 in the Elementary School or 22 in the Middle School. Preschool classes range from 12-16 students with two full-time teachers.


Boulder Country Day has intentionally chosen to focus on preschool through eighth grade and we believe it is among our greatest assets. We firmly believe that a PS-8 school environment offers distinct advantages during the most critical years of a child’s intellectual, social, and emotional development.

Dedicated faculty and Staff

We believe that a caring and dedicated faculty and staff are the "heart and soul" of our school. Ours share a deep optimism for children and a love of their profession.

International, National, and State Accreditations & Affiliations

We believe in continuous school improvement, and, as such, seek accreditation from organizations that focus on that process. BCD is accredited by the Association of Colorado Independent Schools (ACIS), recognized by the Colorado Department of Education, a member in good standing of the National Association of Independent Schools (NAIS), and an authorized International Baccalaureate (IB) World School. We were the first school in the world to meet the standards of all of these organizations.

Committed and Engaged Parent Body

We believe education works best when schools and families partner for the benefit of the students. Committed and engaged parents are the keys to the success of those partnerships, and our Portrait of a Parent outlines the embodiment of that role at BCD.

Inviting Campus

We believe that a safe, clean, and age-appropriate campus improves learning and enhances student engagement. BCD is situated on 5.5 acres campus located in the Gunbarrel neighborhood of Boulder. The campus nestles up to the Twin Lakes open space. 

Outstanding Outcomes

We believe our graduates should be socially and academically confident, technologically savvy leaders who are prepared for today’s and tomorrow’s challenges. They should strive to do their best and should act as honest, effective communicators who care about their communities. Our alumni matriculate at a variety of local public and private high schools along with out-of-state boarding schools. They typically enter into honors, AP and pre-IB courses and state that BCD prepared them exceptionally well for the social and academic rigors of high school.
We also believe that 3rd party assessment is crucial to the success of our students and our school. Annually, we assess our students to determine the progress they have made, to identify areas of strength and weakness, and to evaluate pieces of our program. We use the Educational Records Bureau’s (ERB) Children’s Progress Academic Assessment (CPAAA) for Kindergarten – 2nd grade and the Comprehensive Testing Program version 4 (CTP 4) for 3rd – 8th grades as our assessment tools. We receive robust score reports on the student, class and school levels, which allow us to evaluate our progress and compare ourselves to leading independent schools throughout the United States.
