Measuring the Efficacy of Education: A Possible Methodology

Given the mission of education to enable upward mobility, an obvious methodology for measuring the efficacy of education suggests itself: measure the decrease in the level of correlation of student performance on family background from primary 6 to secondary 4/5.

It goes without saying that student performance at Primary 6 is strongly related on family background. Given that secondary school is a substantial part of the Singapore education experience, where academic preferences are formed, the Secondary 4/5 level is a good time to make the comparison. In fact, a first reading may be obtained at the end of Primary 1/2, which will be very strongly related to family background.

Any competent econometrician would be ale to do the analysis given the data. We should be measuring this and using it as a KPI.
