More than 50 colleges and universities will visit Allendale Columbia this fall, giving our students the opportunity to connect directly with admission counselors right here on campus!

Students can explore colleges they may not have the chance to visit in person, ask thoughtful questions, and begin building relationships with the people who may one day read their applications.

Admission counselors return to AC year after year because they know our students. They value their curiosity, strong academics, and genuine engagement, making these visits an important part of the college search process.

Binghamton, Mount Holyoke, Union, Gettysburg, Providence, and Case Western Reserve have already confirmed visits, with many more colleges scheduled throughout the fall.

Congratulations to our AP students and teachers on another fantastic year!

With AP results released this week, we are proud to share that AC students continued our upward trend, with 80% of students earning at least one score of 3 or higher—our highest percentage in the past five years and well above the national average. Our students also completed a record 190 AP exams, a reflection of their willingness to challenge themselves with college-level coursework.

A few highlights:
• 100% of students earned a 3 or higher in AP English Literature, AP Spanish Language, and AP Music Theory
• 92% earned a 3 or higher in AP Biology
• 88% earned a 3 or higher in AP World History
• 84% earned a 3 or higher in AP English Language

Congratulations to all of our students and teachers on these outstanding results!

As we reflect on America’s 250th birthday, we’re looking back on a memorable journey for our 8th graders to our nation’s capital! 🇺🇸

During their trip to Washington, D.C., students stepped into history as they explored meaningful landmarks and connected classroom learning to real-world experiences.

From visiting monuments and museums to walking through the stories of our nation’s past, the trip was filled with discovery, reflection, and unforgettable memories.

We’re grateful for the opportunity to help students experience history beyond the classroom. ❤️🤍💙

This spring, our Girls on the Run team laced up, showed up, and inspired one another every step of the way! 💙

Together this group of fourth and fifth graders built confidence, strengthened friendships, and discovered their inner strength while preparing for a celebratory 5K. A huge thank you to coaches Kaleen Burns, Linda Jaimes, Carlin Jones, and Abbi Tabone for giving their time and energy to support these incredible girls!

Beyond running, the team focused on making a difference through their Impact Project. The girls identified a need in their community, worked together, and created adoption posters for Lollipop Farm while making pet toys for shelter animals.

The team also celebrated being active together with a special visit to Ninja Warrior Factory, where they ran, jumped, climbed, swung, and encouraged one another through every challenge.

We are so proud of our Girls on the Run team for the confidence, care, and character they showed this year!

What an incredible weekend celebrating Reunion with more than 175 alumni and faculty! 💙

Our All-Alumni Cocktail Party was a wonderful opportunity to reconnect, share memories, and celebrate the lasting bonds that make the AC community so special.

A highlight of the weekend was honoring Nancy Hodge Lee ’46 with the 2026 Distinguished Alumni Award. Her lifelong connection to AC and the impact she has made throughout the years beautifully represent the spirit and values of our community.

Thank you to everyone who returned to campus and helped make this Reunion celebration one to remember!

Reflecting on Commencement and celebrating the incredible Class of 2026!

What a special day honoring our seniors and the journey they’ve taken at Allendale Columbia. From their first days on campus to this milestone moment, we’ve watched them grow, discover their passions, and build lasting friendships.

Congratulations, graduates! We are incredibly proud of all you have accomplished and look forward to seeing the impact you will make in the world.

This May Term, students traveled to Morocco for a transformative Global Engagement experience centered on service, entrepreneurship, and cultural immersion. 🇲🇦

From exploring the historic city of Fes to working alongside a women’s cooperative in the Atlas Mountain village of Maghoura, students gained firsthand insight into community impact and local enterprise. Along the way, they hiked mountain trails, visited Chefchaouen, Tetouan, and Tangier, and experienced the beauty of Morocco’s Mediterranean coast.

Through meaningful connections and unforgettable experiences, this journey brought learning to life far beyond the classroom.

AC spirit never goes out of style!

Check out our new Allendale Columbia t-shirts, designed by alumnus Grant Conboy ’06 and inspired by the iconic birch trees that make our campus so special. Available in White and China Blue Comfort Colors tees.

A special thank you to Jack Wheeler ’21 and KB Graphics for helping bring these designs to life.
