We develop and estimate an equilibrium model of ability tracking. A school allocates students into tracks based on their ability and then chooses trackspecific inputs to test score production. Parents choose parental effort in response. We estimate the model using data from the ECLS-K. We use the estimated model to quantify the effects of allowing ability tracking, making proficiency standards ...
