Update: A PR person who has apparently been retained to represent inBloom strenuously objected to Greg's characterization of her client's practices below. She sent me an email, which I've posted to the comments. I've also made a factual correction, regarding constraints, below (look for the strikethrough)

Greg Costikyan sez,

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.
