At a Glance

Allendale Columbia School is a diverse, independent, co-ed school for students in Little School (18-36 month-olds) through grade 12 located in Rochester, New York.

About Us

Founded in 1890, Allendale Columbia School has been at the forefront of education in Rochester for more than a century.

As an independent school, we do not teach to the test and our teachers are not bound by the Common Core. Instead, our faculty members are empowered to develop a relevant and rigorous curriculum that challenges students to dig deeper and question more as they apply their learning to the real world and seek to discover their place in it.

Through this personalized exploration of learning, students have countless opportunities to express themselves, discover their passions, pursue real world projects, and achieve academic excellence.
