With over 40 years of experience, we are one of the most progressive high schools in the area. Our focus is not only on academics but also on social and emotional learning, providing students with a well-rounded education.

We offer a supportive and relationship-based environment where students can collaborate, support each other, and understand the world around them. Our small school environment ensures effective academic instruction with a low student to faculty ratio, allowing students to excel in their subjects. We welcome students with various needs, including learning disabilities, anxiety, depression, ADHD, and more.

Our curriculum includes English, Social Studies, Math, Language, Science, Physical Education, as well as a range of electives. In addition, we offer experiential learning opportunities, leadership development, internships, and community service. At September High School, we believe in celebrating each student's individuality and providing them with the necessary skills and education to thrive in high school and beyond.
