Can a Public-Private Partnership Improve Liberia’s Schools?

After one year, public schools managed by private operators raised student learning by 60 percent compared to standard public schools. But costs were high, performance varied across operators, and contracts authorized the largest operator to push excess pupils and under-performing teachers into other government schools.

Internationally Comparable Mathematics Scores for Fourteen African Countries - Working Paper 444

Internationally comparable test scores play a central role in both research and policy debates on education. However, the main international testing regimes, such as PISA, TIMSS, or PIRLS, include very few low-income countries. For instance, most countries in Southern and Eastern Africa have opted instead for a regional assessment known as SACMEQ. This paper exploits an overlap between the SACMEQ and TIMSS tests—in both country coverage, and questions asked—to assess the feasibility of constructing global learning metrics by equating regional and international scales. I find that learning levels in this sample of African countries are consistently (a) low in absolute terms; (b) significantly lower than predicted by African per capita GDP levels; and (c) converging slowly, if at all, to the rest of the world during the 2000s. Creating test scores which are truly internationally comparable would be a global public good, requiring more concerted effort at the design stage.

Scaling Up What Works: Experimental Evidence on External Validity in Kenyan Education - Working Paper 321

We investigate heterogeneity across beneficiaries and implementers—in a randomized trial of contract teachers in Kenyan schools. The data show a stark contrast in success between the government and NGO arm that can be traced back to implementation constraints and political economy forces put in motion as the program went to scale.
