In lieu of traditional exams in all subjects, the final four days of each semester will provide each class an opportunity to meet for a single two-hour block. The uses of these blocks will vary from course to course and teacher to teacher. While some will be used for traditional cumulative exams, others will be used for alternative assessments, presentations of projects, field trips, or as a longer-than-usual stretch of uninterrupted teaching time. Each of the four days will include two learning/assessment periods organized by scheduling time block (A, B, C, etc.).
