Project Mastery was a family literacy program that served 30 adults and 40 children in its first year of operation. Participants were parents and adult siblings of present and past English-as-a-Second-Language programs and students of limited English proficiency (LEP) in kindergarten through grade 5. It was designed to support English language development in both adults and children, and also provided mathematics instruction to participating children after school hours. Child care and educational activities for preschool children were added to enable parents to attend project activities. A unique program feature was intergenerational ESL literacy classes to enable newly-arrived families to develop language skills rapidly and increase parent interest in children's schooling. Participating teachers were provided with staff development opportunities. The project met its objectives for parent involvement, and partially met its objective for children's development of English language skills. Objectives for adult English language skill development and mathematics could not be assessed. Recommendations for program improvement include modifying the objective for adult English language skills for better assessment, and augmentation of children's English language skills development, particularly through peer tutoring or individualized instruction.
