Classes For Credit

Marlborough Summer is pleased to provide challenging academic classes that can be taken for credit. The courses are designed and taught by Marlborough faculty, and are open to students entering Grades 9-12 from any school.

Why take a class in the summer? This is a great chance to dive into one content area without the demands of the regular school day. For-credit classes can help you complete a graduation requirement in order to free up space in your schedule during the academic year. Prerequisites are required for some for-credit courses. Please check with your school to ensure credit will be awarded for the class(es).

Registration starts March 2, 2026.

Emergency Preparedness and Water Safety

Marlborough Summer School offers the opportunity for students entering Grades 10–12 to complete the Emergency Preparedness and Water Safety course requirement in a two-week course. This required course fulfills one of the Marlborough School graduation requirements.

Through this course, students learn to care for others in emergency situations while learning about their personal safety in diverse emergency medical situations.

The main components of the course include: First Aid, CPR, Patient Assessments, and Water Safety. Students will participate in scenarios, practical skill testing and simulated rescue drills, and generally train to be well equipped to handle emergency events. Students will also develop team leadership skills by using strong collaborative and communication skills during class exercises.

Geometry for Credit

This course is designed for students who have completed Algebra 1 in 9th Grade and will be entering 10th or 11th Grade in the fall. Topics include Euclidean geometry, introduction to logic, trigonometry, coordinate geometry, and transformational geometry. Students taking this course will need a scientific calculator. This course satisfies the regular Geometry requirement at Marlborough. A minimum of an 80% class average allows a student to enroll in regular Algebra II with Trigonometry in the fall.
