Casco Bay High School says

Casco Bay High School (CBHS) is a small and rigorous public high school that reflects the increasing 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 3R’s: Rigor, Relevance, and Relationships. The Class of 2009 was our first graduating class, and nearly 100% of our graduates have been accepted to college. On the annual Maine High School Assessment, 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 “Mentor School” in the EL Education (formerly Expeditionary Learning) national network of schools ( In their spring 2011 “Comprehensive Program Review,” the Great Schools Partnership concluded, “the school has demonstrated consistently high levels of accomplishment in every dimension with exemplary performance… in many areas.” In 2012, CBHS was named one of Maine’s top high schools by US News and World Report. In 2014, CBHS was selected as one of twenty “Deeper Learning” schools in the country and was awarded the Larry O’Toole Award by the Nellie Mae Foundation for “advancing student-centered learning” in New England.



CBHS students participate in a demanding, college preparatory curriculum. Students typically enroll in six year-long courses that meet for nearly 90 minutes every other day. Additional support and accommodations are provided as necessary for our English language learners and special education students. 41 credits are required to graduate from all Portland Public Schools.

Humanities courses (9-12) integrate English and social studies and meet daily. Our math program is inquiry-based and technology rich. Science courses are lab and field-based. French 2-4 and Spanish 1-4 and Chinese 1-2 emphasize oral proficiency for use in real contexts. Honors (or “exceeds”) work is available in each course. We also offer three AP courses. Seniors who meet requirements for exceptional, deep achievement in science, technology and math (STEM) courses and activities will receive a STEM endorsement on their diploma. Through our U. Start Ahead Program, upperclassmen are encouraged to take at least one college course before graduation. In Senior Humanities, students prepare for life after graduation and complete a customized senior project, the Senior Expedition. Crew is students’ family during their time at CBHS. Crews and crew advisors meet 3 hours weekly, focusing on holistic student development as well as college and career preparation.



Public schools are supported through local, state, and federal funding, and do not charge tuition to students who attend them.
