It is not actually true. The school district acts as the agent for the child and it is their responsibility to spell out in contracts what the vendor can do with the data (in most cases). They are bound by various state and federal laws on what they can allow as well as what they must require of vendors but in general the parents don't have to provide consent on a case-by-case basis. Of course, parent can talk to the district about it and potentially have the child not use the service but this is not something vendors would ask of each parent.
