This paper describes the development of a simulation technique that can be used in the training of infant day care administrators and personnel. The planning of the simulation was designed as a training experience for graduate students in an early childhood education program. Students, faculty members and child care professionals from the community were asked to role play the parts of director, teacher, parent, aide, community representative and junior college representative. Participants were divided into small groups and given envelopes of "in-box" materials, letters and memos on specific situations and problems typically confronting day care personnel each week. In the first phase of the simulation, all participants assumed the role of the director. In the second stage the scene shifted to a staff meeting for which different roles were assigned. The third phase was an advisory board meeting. Participants attempted to organize materials in terms of priority within each phase of the simulation and solve the most important problems. Summaries of small group discussions and consensus on topics were recorded. These records were used in an evaluation of the session, as were summary evaluations by individual participants and evaluation forms filled out at the end of group simulations. The evaluation procedure is discussed in detail, and recommendations for potential use of the simulation are made. Appendices include the background information presented to participants: a description of the simulated center, in-box materials, and the evaluation form used by participants. (SB)
