Allendale Columbia is a school that is evolving - I love what the school is doing with May Term offerings, and it allows for my two children to be seen as individuals with individual needs. They are both actively involved in music, and extra-curricular activities, like the Lego Robotics teams and pit band. It is a wonderful feeling knowing that the sports program is a no-cut policy, where my kids can feel like they can try a sport and be part of a team without being cut out of the process from the start. I highly recommend this school for anyone who wants a unique, student-centric, and high quality education for their child.

Allendale Columbia is a completely different school than it was two years. Thanks primarily to the arrival of Mick Gee, the new Head of School in 2012 and John Sullivan, the new Head of the Lower School in 2011, AC is being restructured and set on a new path. The school has freed itself from standardized testing and bureaucrat regulations to instead enable it to quickly respond to new educational trends and the are responsible for the fine strokes. The students feel like they are part in school seven days a week if she could. Another key item that makes AC noteworthy is their ability to serve children with needs on both ends of the spectrum. They have employed math and reading stimulation. At the beginning of the 2012 school year, AC responded to a need in a matter of weeks to implement their new STEM program

As it concerns the Lower School, Allendale Columbia is a completely different school than it was two years. Thanks primarily to the arrival of Mick Gee, the new Head of School in 2012 and John Sullivan, the new Head of the Lower School in 2011, AC is being restructured and set on a new path. The school has freed itself from standardized testing and bureaucrat regulations to instead enable it to quickly respond to new educational trends and the individual needs of the students. Lower School education is now project and inquiry based learning with real world relevance. The faculty paints the broad strokes of the curriculum, but the students are responsible for the fine strokes. The students feel like they are part of a higher purpose and can participate in projects that they are passionate about, have a stake in, and can help make a difference. Learning is now interesting and fun.

Parents are involved and have many opportunities to connect with other parents to discuss their child(ren) and to support each other. This spirals into students who benefit from this community atmosphere and who develop into mature adults.
