Interestingly, the Delphian School in Oregon, where the "Hubbard learning tech" has its full power unleashed upon a minor student population, does not take part in the annual statewide school examinations in Oregon, and there is therefore no objective comparison of the results of the "learning tech" with ordinary public schoolteaching.
(Which is especially interesting in the light of the fact that private schools have a big advantage over the public schools in that private schools can simply expel bad students, which the public schools cannot, and guess where those bad students expelled from the private schools end up? you guessed it, in the public schools, helping drag down the comparative student performances still further, all this being what has been called "the dirty little secret" of private versus public education in the US.)
Anyway, could any evidence be clearer that Scientology wants no objective comparisons between "the power of the learning tech" and ordinary pedagogy?
The Delphian School and the "learning tech" are obviously fraudulent.
And Scientology obviously fears to match its "learning tech" against ordinary pedagogy under objective testing circumstances.
