ABSTRACT
In this chapter we explore the Lean implications of the Visible Learning METAX data about the structural dimensions of the school. This includes how much funding to allocate; the size, shape, and location of school buildings; class size; the length of the school day and year; and whether students that are unsuccessful should repeat the whole year over again. Each of these structural decisions represents a trade-off between financial costs on the one hand and expected returns to student access and learning on the other. We make the case that money only matters to a point and that structural investments like reducing class size, upgrading school buildings, and increasing the duration of schooling cost much but deliver correspondingly little.
