Quite a few proposals around improving performance the academic performance of students involve very costly interventions. Even though many of these surely come accurate on the cost-benefit tests, but they surely can be enormously challenging, both politically and economically, to ensure a successful functioning and implementation. A possible way involves changing the ways in which schools are conducted. For instance, in a recent policy proposal, Jacob and Rockoff suggest three low-cost ways to conduct schools that can ensure maximised student performance: i. clubbing elementary and middle schools into single buildings; ii. optimize teacher assignment; and iii.
