inBloom, a Gates-funded non-profit to harness data to improve grade school education, has partnered with New York and eight other states to encourage the development of apps to "further education" by using intimate data about students, without parental consent and with no ability for parents to opt out.
Among the data shared are name, address, phone numbers, test scores, grades, economic status, test scores, disciplinary records, picture, email, race, developmental delay... just about everything conceivable, and all specific, none of it anonymized. inBloom has arrangements with nine states (New York, Massachusetts, Louisiana, Colorado, Illinois, North Carolina, Georgia, Delaware and Kentucky) to do this.
The XML schema used are downloadable here. Anyone can register as a developer and start using "sample" data, but "real" data is supposedly only available to developers with contracts with a school board. But this includes for-profit, third party developers, such as, say, Amplify, a News Corp subsidiary with a contract with New York. And it doesn't appear there are any constraints on their use of this data.
