We are joined by Dr. Thomas Guskey. Tom has a storied career in the field of education.  This includes experience as a classroom teacher, school administrator, researcher, professor, and author.  You probably know him best as an authority in the area of grading, though this is just one of his areas of expertise. In this interview, we get to know Tom and focus on the book What We Know About Grading: What Works, What Doesn’t, and What’s Next published by ASCD.  Tom and Susan Brookhart put this together with the support of many contributors so that practitioners have what they need to know about grading all in one place.
