  We report our experiences implementing standards-based grading at scale in an
Algorithms course, which serves as the terminal required CS Theory course in
our department's undergraduate curriculum. The course had 200-400 students,
taught by two instructors, eight graduate teaching assistants, and supported by
two additional graders and several undergraduate course assistants. We
highlight the role of standards-based grading in supporting our students during
the COVID-19 pandemic. We conclude by detailing the successes and adjustments
we would make to the course structure.
