St. George's School provides a rigorous college-preparatory curriculum, high standards, and dynamic classroom discussion. Round tables are prevalent and coincide with our belief in the virtue of small classes and in the benefits of active dialog and debate. Learning at St. George's School has to do with knowing the teacher and the subject matter, and we celebrate the growth that takes part at the heart of our challenging and democratic process.

Course planning at St. George's School is an individualized process. Each new student's course of study is individually planned with the advice of the director of studies. Course levels are assigned by department heads on the basis of academic proficiency, not grade level or age. The course-planning process is significant because it enables each student to set goals for the next school year and subsequent years, to explore the numerous options for building on his or her particular strengths, and, through the choices made, to clarify academic priorities.

Parents and students receive grades and written comments three times a year (after Thanksgiving vacation, after midyear exams, and after final exams) and at various additional academic checkpoints when necessary. Included are effort evaluations of exemplary, satisfactory, needs improvement, or unsatisfactory. St. George's issues letter grades with pluses and minuses. A grade of B or better is considered an honor grade. D- is the lowest passing grade.
