In many ways,Japan is an embodiment of meritocracy, stressing academic achi

However, around that time, a progressive movement succeeded in implementing
detracking policies in some prefectures, which also had some unintended co
nsequences, the opposite of their egalitarian intentions. This article pres
ents case studies and multivariate analyses that find that prefectures with
egalitarian detracking reforms had the most flight from public to private
schools and the emergence of the most withinschool grouping. We conclude th
at when policies tried to get less seperation of students among public scho
ols, separation emerged in other ways. The results have implications for th
e design of tracking policies.
