Professor Mark Bray's publication Double-Shift Schooling: design and operation for cost-effectiveness is the second edition of a valuable document which analyses the effectiveness of a strategy that has been adopted, by many governments, to maximize the use of school premises for different cohorts of students in a single day. In addition to double shift schooling, Professor Bray explains the use of the school plant for triple and even quadruple shifts in some countries. These arrangements are seen as cost effective measures for addressing some of the issues associated with increasing access and the need for expansion of educational opportunity to meet economic as well as social objectives.
