Our goal is to produce a global and comparable dataset that allows researchers to explore different questions in the pursuit of “what works” to improve schools and education around the world. At this point the project is too young, but the map below tracks the number of countries where active data collection projects exist or were completed, with information on their sample size and dates of completion.
