There are several agencies at the state level and the federal level (everything from education to consumer protection to lawmakers - federal Senate) looking at how ISAs should be regulated or what rules they should have in different scopes (they are not just used for schools but all kinds of things). There haven't been any firm decisions made. Right now they are private contracts between two people and not a financial object. So they are likely avoiding using ISAs because of some concerns or interactions with some agency that made them deem it not worth the effort to work on at this time.
