For well over a year, school shutdowns and sputtered reopenings have tested educators' resourcefulness and resolve. As the new school year begins, many are reflecting on small triumphs and lessons learned from that experience.

The author believes that such teams, which enabled schools to respond quickly and often wisely to unprecedented demands, can now propel schools to become even better as they move beyond crisis mode. In this article, the author presents why teacher teams are more critical than ever. Effective instructional teams helped schools navigate the pandemic--and they are essential to helping schools thrive in its aftermath.
