I don't even know what you're talking about besides a plug for a homeschooling crank. If you think "reliably detect the optimum training environment" is what we do now, you know little about the education system.
"crank": An eccentric person, esp. one obsessed by a particular subject or theory.
John Taylor Gatto is an education crank who has dedicated his life to improving education and fighting schooling. I think we would do well to have more such cranks among us.
Gatto would have us all homeschooling. Read up on New Jersey Youth Challenge Academies for a very on-point counterexample.
