IES Research Training Institute: Cluster Randomized Trials

This report provides information about principals' satisfaction with various environmental factors in their schools, and the extent to which they perceive those factors as interfering with the ability of the school to deliver instruction. The report also describes the extent of the match between the enrollment and the capacity of the school buildings, approaches for coping with overcrowding, the ways in which schools use portable (temporary) buildings and reasons for using them, and the availability of dedicated rooms or facilities for particular subjects (such as science labs or music rooms) and the extent to which these facilities are perceived to support instruction.
