Brown's open curriculum includes a simplified grading system that encourages students to explore many disciplines. When registering for classes, Brown students indicate whether they would like to receive a letter grade (ABC/NC) or mark of satisfactory/no credit (S/NC). A small number of instructors require that their course be taken S/NC.
Instructors establish the standards of achievement for their classes. Grading criteria should be published in course syllabi and on course websites. Course instructors should discuss required assignments and grading policies at the beginning of each term and provide clear and timely evaluation of student work.
