The glossary describes widely used school-improvement terms, concepts, and strategies. It currently features more than 500 terms and 150 in-depth entries on K–12 public education and education reform in the United States. Each entry includes a general definition of the term, a discussion about how the concept or strategy intersects with efforts to improve school performance or student achievement, and an overview of related debates, including the major arguments for or against particular reforms. The glossary is designed to be a neutral observer, and the writers and editors worked to create entries that are factual, objective, and impartial.
