This guide, in Spanish, is intended to help Pennsylvania parents of preschool children with special needs to understand their rights and assist in the design of an appropriate early intervention preschool educational program. An overview of special education laws focuses on the Individuals with Disabilities Education Act, Part B. The main sections of the guide provide information on: referral; transition at age 3, which includes transfer of responsibility from the Department of Public Welfare to the Department of Education; the multi-disciplinary evaluation team, such as required members; the multi-disciplinary evaluation, including required areas for evaluation; what makes an evaluation "appropriate," such as appropriate tests and testing environment; independent evaluations; re-evaluations; the comprehensive evaluation report, including required components; eligibility; the individualized education program (IEP) and its required components; services and personnel; placement; community childcare or preschool; other IEP requirements; conflict resolution, including complaints, mediation, conferences, and hearings; and transition to school-age programs. Three appendices provide a checklist of preparation steps for the IEP meeting, a list of suggested questions for parents to ask, and a glossary of abbreviations. (DB)
