> Argentina's ministry of education did something like this with university software. The one used by students to sign up and by teachers to track grades, etc.

For what it's worth, this seems roughly equivalent to Moodle, which is open-source (GPL) and used globally, apparently especially popular in some of western Europe, the US, etc. [1] School systems can and do of course customise it as needed.
