With the quota removed, the selection criteria for teachers ended up with worse student outcomes. The opposite should have happened because removing the quota should have resulted in better teachers on the margin. Therefore they suggested perhaps the selection criteria did not consider some criteria such as mathematics background or native language expertise that was more often found in men (the group favored in the quota). If this is the case, they should add these as criteria, student outcomes would improve, and the gender disparity would decrease. It isn't that students benefit from having more male teachers. It is that the selection criteria was choosing marginal women over men who actually were better teachers.
