This information has nothing to do with helping children learn. It has everything to do with exploiting children for profit.
These databases containing your child's personal information will be considered proprietary and you will not be allowed to see it.
However, your child's personal data will be available to insurance companies, potential employers, car dealers, banks, drug companies, and other corporations and government agencies willing to pay a hefty fee for the privilege of spying on your child's life.
This data base will allow any teacher, future employer, or any "authority figure" holding a grudge against you or your child, to put negative "information", whether true or totally fabricated, into these proprietary databases, to which, since they are proprietary, even though sold to practically anybody, you will not have access or oversight.
The possibility for abuse is endless. The potential abuses perpetrated by "legitimate" buyers of your child's data far exceed the threat of hackers stealing it. One has to understand the big picture.
How soon we forget the abuses of credit rating company databases.
