Estimates suggest that 20 to 25% of U.S. students change schools each year, and this figure is higher in school districts with a relatively large immigrant population. The guidelines in this technical assistance packet provide strategic suggestions for welcoming newcomers to a school or district, something that has become an essential facet of schools. Chapter I presents a welcome program with strategies to enhance welcoming and increase home involvement in schooling over three overlapping phases. The first involves a broad focus that uses general procedures to welcome students and facilitate adjustment and participation. The second phase targets those who need a little more assistance, such as personal invitations or ongoing support for interacting with others or becoming involved. The third phase narrows the focus to those who have not made an effective adjustment or who remain uninvolved. Each of the intervention phases involves the following major intervention tasks: (1) establishing a mechanism for planning, implementing, and evolving program activity; (2) creating welcoming and initial home involvement strategies; (3) providing social supports and facilitating involvement; and (4) maintaining support and involvement. Key elements and activities are suggested for welcoming programs. Guidelines are included, in English and Spanish, for parents to help their children adjust to a new school. A section on welcoming "on a shoestring" provides suggestions for cost cutting and enlisting the support of local businesses. Chapter II contains 20 selected references, with annotations for some, on welcoming and social support. Chapter III lists experts in the "Consultation Cadre," who can provide technical assistance and support. Chapter IV contains an article by Mary Beth DiCecco entitled "Welcoming: Facilitating a New Start at a New School." Chapter V contains two sample digests from the Educational Resources Information Center (ERIC) as examples of the type of information available through ERIC. A final chapter lists resource aids for welcoming, social support, and mapping a school's resources for helping students and families make the transition to a new school. (SLD)
