Who We Are

Casco Bay High School (CBHS) is a small and rigorous public high school that reflects the diversity of Portland, Maine (population 64,000). Founded in 2005, CBHS is a school of choice for nearly 400 students (9-12). At Casco Bay, we challenge and support our students to become college-ready through our 3 R’s: Rigor, Relevance, and Relationships. The Class of 2009 was our first graduating class, and nearly 100% of our graduates have been accepted into college. On standardized tests, Casco Bay students routinely exceed state and district averages - as well as demographic expectations - in reading, writing, science, and math. 

Casco Bay High School is proud to be a credentialed, lead school in the EL Education (formerly Expeditionary Learning) national network of schools. CBHS has been named one of Maine’s top high schools by US News and World Report and Niche.com. CBHS was chosen as one of twenty “Deeper Learning” schools in the country. The National Education Policy Center selected CBHS as a “School of Opportunity (Gold Level),” the first ever in Maine.

What We Do: Learning Expeditions

Our instruction results in quality work about genuine problems for a real audience. Learning Expeditions are long-term in-depth studies of a single topic that explore compelling social and environmental questions, incorporate vital standards, involve fieldwork, and culminate in an authentic project, product or performance. The Class of 2023 has undertaken learning expeditions on topics ranging from climate change to the Israeli-Palestinian conflict.
