In shared decision making (SDM), principals collaborate with teachers and sometimes parents to take actions aimed at improving instruction and school climate. While research on SDM outcomes is still inconclusive, the literature shows that SDM brings both benefits and problems, and that the principal is a key figure. This brief offers a sampling of recent research on shared decision making: (1) "Shared Decision-Making" (Lynn Balster Liontos and Larry Lashway); (2) "Principals' Skills and Knowledge for Shared Decision-Making" (Kent Peterson, Kubilay Gok, and Valli D. Warren); (3) "Influences of Shared Decision-Making on School and Classroom Activity: Conversations with Five Teachers" (Gary A. Griffin); (4) "The Principal as Mini-Superintendent under Chicago School Reform" (Bruce R. McPherson and Robert L. Crowson); and (5) "The Fire Is Back! Principals Sharing School Governance" (Jo Blase and Joseph Blase). (LMI)
