Can Outsourcing Improve Liberia's Schools? Preliminary RCT Results

Last summer, the Liberian government delegated management of 93 public elementary schools to eight different private contractors. Given the intense controversy around the program, the government—with some encouragement from our colleagues at Ark Education Partnership Group, who helped manage the program—agreed to randomize the allocation of schools during the pilot, and the three of us partnered with Innovations for Poverty Action (IPA) to evaluate its impacts.

Will an RCT Change Anyone’s Mind? Should It?

We respond to critics of our evaluation of Liberia’s “partnership” school program, distinguishing legitimate concerns about the charter-style program itself—which can be turned into testable hypotheses—from methodological limitations to what an impact evaluation can show.

The healthiest parts of the debate have been about the need for transparency, data sharing, and more replication in science. Here, we’re going to focus here on the narrower question of the evidence for mass deworming specifically, which is where some journalists have gotten things quite wrong.
