However, some systems only achieve these goals at the expense of educational quality. Planners may be faced with difficult choices when designing systems. Drawing on experiences in a wide range of countries, this publication highlights the advantages and problems of double-shift systems. Comparison is made with single-shift systems, and also with systems having triple, even quadruple shifts.--Publisher's description.
