The call to restructure schools is born from a new set of challenges facing U.S. society as well as its education system. This paper describes the process followed by 12 schools that participated in meeting the challenges in the "Schools of Tomorrow...Today" (ST/T) project, supported by the New York City Teacher Centers Consortium (TCC) of the United Federation of Teachers. The project was intended to be a means for changing communications among the staff and parents at schools, changing school-site governance, and being a mobilizing force to improve the education of children. The TCC selected 12 schools from 135 that responded for a place in the project. Each school set up a ST/T team and in the spring and summer of 1990 TCC researchers were able to observe the process of restructuring firsthand. Each school is described, and the context gives demographic data and general information pertaining to the school's unique circumstance. The focus of the ST/T project in the school is then outlined, followed by the learning experiences, barriers, ongoing problems, and dilemmas faced. Each case study concludes with identified needs. In addition, some case studies report on the effects of the restructuring effort. (RR)
