Double-shift Schooling primarily aims to extend access and minimise unit costs. However, some systems only achieve those goals at the expense of educational quality. Policy-makers may be faced by difficult choices when designing systems. Drawing on experiences in a wide range of countries, this book highlights the advantages and problems of double-shift systems. Comparison is made with single-shift systems, and also with systems having triple or even quadruple shifts. The book will be useful both for national and regional policy-makers, and for headteachers and others responsible for running double-shift schools. This is the third edition of a book first published in 1989 and updated in 2000.
