A practicum project implemented a developmentally appropriate intervention to increase school success for at-risk children in kindergarten through grade 3. Two corollary aims of the project were to determine the causes of at-risk status before retention or school failure occurs, and to involve parents in their children's educational process. An extended-day early intervention program (after school) 2 days per week for 1 hour per day was implemented to help Chapter 1 students experience success in language arts. Eight home-school partnership workshops in English and Spanish were provided to the parents of all students. In addition, there was a 2-week program of daily parent involvement that included a home-school lending library. Results of student skills tests and pre- and post-program surveys indicated that the parent involvement program was the most successful part of the practicum. Although the at-risk students did show gains, the gains were not as expected. (Six appendixes include questionnaires, parent letter, extended day student survey, and early intervention for school success continuum.) (HTH)
