History

SDE was founded in Peterborough, New Hampshire, in 1986 by Jim and Lillian Grant with the original goal of providing New England teachers the opportunity to learn the best techniques from the best teachers in the region. Motivated by Jim’s personal goal of helping to create classrooms where all students can succeed, SDE has grown to become one of the nation’s leading providers of professional development for PreK through grade 12 educators and administrators.

Since 1991, SDE has been a proud member of a family of companies owned by Highlights for Children, Inc.
