The Wallace Foundation released the study Expanded Schools National Demonstration: Lesson for Scale and Sustainability. The study offers recommendations based on the experiences of 10 schools that employed the ExpandED model that changes the use of time by strategically adding time to the school day, enhancing skills and knowledge by engaging students in enrichment opportunities beyond core academics. The ExpandED school model seeks to use partnerships between public schools, community organizations and intermediary organizations to increase those enrichment activities. Researchers studied the use of this model in 10 schools in three cities, New York City, Baltimore and New Orleans over four years. The study identifies the parts of the model that were easiest for schools to implement and parts that were the most challenging.
