TL;DR: There is a company called Bridge International Academies trying to improve education in 3rd world countries by bringing in completely untrained teachers. They are following the typical start-up path, trying to scale up rapidly.
One of their main investors is the World Bank.
The World Bank has an internal team that investigates its investment for ethics, called the CAO (Compliance Advisor Ombudsman).
The CAO found evidence of large amounts of child abuse (sexual and otherwise). The World Bank responded by not renewing the contract of the head of the CAO, by attempting to fire the lead investigator into Bridge, and by signing a NDA with Bridge that makes it very difficult if not impossible to release any discovery of wrongdoing.
As a personal note, The Intercept is one of the last remaining news outlets that actually does meaningful investigations and shines light on the corrupt. If you can spare anything, send them a donation.
