That’s the first I’ve heard of this. I cannot find any weakness in his proposal. Private credentialing, why not?

The subject of credentialing exams or qualifying exams I was starts on page 104 under the topic heading of “An Alternative” It is about 4 or 5 paragraphs long.
By the way...The entire paper is **very** interesting!
The more parents take charge of their own child's education the support for government education will be undermined. The more quickly a child can move through his education the less he will use the government schools.
Government schools need two things: Students and voter who will give them money. Credentialing exams robs the government schools of both students ( and the money that comes with each child) and voter support.
Also...ALL of K-12 could be on the Internet. It could even be completely free to the student if the the producers of the on-line material and the testing agencies accepted advertising. In fact, excellent on-line teacher could become very rich ( Mark Zuckerman rich!)
