This report examines the relations between school design and student productivity and informs policy decisions. It contains three analytic sections: an analysis of school facilities characteristics and student productivity, a review of other research examining school facilities and student productivity, and an analysis of the need for school construction and renovation within the context of Arizona and Students FIRST (Fair and Immediate Resources for Students Today) legislation. Data collected from 394 schools representing 34,658 students show that school enrollment size is significantly more important to student achievement for Title I students than for non-Title I students. No relationships were found for academic achievement and other school design factors. Relationships between school size and student productivity measures of attendance and promotion (non-academic measures of student productivity) data show statistically small but significant correlations, with larger physical size, higher enrollments, and higher density associated with higher attendance and promotion rates. It is suggested that school administrators and school boards are pressed by the Students FIRST legislation and by the Department of Education's Management and Operations funding to build elementary and middle/junior high schools that are larger than those which support procedures the most achievement by the State's students.
