Upper School students must take and pass a minimum of five one-credit courses per term, fifteen credits per year, and must earn forty-five credits in Forms 4, 5 and 6 to graduate. If a student fails a course, that course credit must be made up. In such a case the student must seek the advice of the Academic Dean.

4th Formers take a minimum of five full credits; many take five and a half or six:
English, math, foreign language (classical or modern);
Choices to fill out the five or six credits include World and the West (either 4th or 5th Form), a lab science, Sacred Studies (for new 4th Formers), an art course, a second language.

(All music courses are half-credit and may be taken on top of five or six full credits, but two together may not replace a full-credit course.)

5th Formers take a minimum of five full credits; many take five and a half or six:
English, math, foreign language (classical or modern);
Choices to fill out the five or six credits include American History or World and the West for those who have not yet taken it, a science, Sacred Studies (for new 5th Formers or those new as 4th Formers who did not take it), a second language, art, history or English electives.

(All music courses are half-credit and may be taken on top of five or six full credits, but two together may not replace a full-credit course.)

6th Formers take a minimum of five full credits; many will take five and a half or six.
All 6th Formers take Expository Writing in the fall and are encouraged to take English electives in the other terms. They are also urged to continue with their foreign language and mathematics. All will take a one-term Ethics course, unless they did so in the spring of their 5th Form year. Whether they will have any other required courses depends upon the extent to which they have completed their diploma requirements. Many electives may be taken on a term-by-term basis.
