Fall Update

At SPS this fall, all courses, other than pre-established online courses, will be offered face-to-face in our New York City classrooms. Some of these face-to-face courses will be offered in the HyFlex format to ensure that all of our students can make progress toward their degree requirements, if faced with delays due to student visas or vaccination effectiveness wait times.
