Project Cuatro Casas was an Elementary and Secondary Education Act Title VII-funded project in its first year in 1993-94. The project operated at one high school in the Bronx (New York) and served 1,074 students of limited English proficiency. Participating students received instruction in English as a Second Language (ESL); native language arts; and the content area subjects of mathematics, science, and social studies. In-house staff development through on-site meetings, tuition assistance for teachers, and a parent involvement component were included. The bilingual students were organized into four houses (the "cuatro casas") to foster a sense of belonging and to ensure personal attention. Counseling for students and parents and intervention geared to attendance were important features. The project met its ESL objectives, a native language arts objective, attendance, staff development, and parent participation. It partially met its objectives for subject content, but did not meet advanced native language arts or peer tutoring objectives. Recommendations are made for better scheduling, peer tutoring, and more parent involvement. Six tables present evaluation findings, and two appendixes describe instructional materials and class schedules. (Author/SLD)
