This report describes the development, implementation, and evaluation of a pilot project by the Studio in a School (SIAS) arts group to place professional artists in six preschools and kindergarten programs in New York City public schools. The SIAS program provided both on-site, hands-on visual arts training of teachers and aides and direct services to children. It emphasized activities that focused on physical handling of materials, sensory exploration, and vocabulary building. Classroom observations and interviews of artists, teachers, and administrators showed a high level of program implementation and satisfaction. Most teachers expressed a desire for an expansion of the SIAS program. Both preschool and kindergarten children showed gains in socio-emotional, linguistic, cognitive, physical and motor, motivational, and aesthetic development. Evaluators recommended that SIAS program administrators: (1) seek funds for the expansion of the project to more schools; (2) encourage closer collaboration between artists and classroom teachers; and (3) provide additional staff development time to teachers and artists to better implement the program.
