No, you proved that you are incapable of analyzing the data. If 90% of teachers are accredited and over half fail tests they give their own students, the accreditation means nothing.
My daughter is certified to teach K-6. She takes continuing education courses and is working towards her masters degree. She graduated with honors.
From what I have seen of graduate teacher education, that doesn't impress. My mother was a teacher with two masters' degrees BTW, and in her latter years should have been fired for incompetence.
I don't know about your state, but in Virginia children who are home schooled receive the lesson plans from the STATE (prepared by teachers) and their tests, etc. have to be sent to the STATE to be graded and their progress noted by TEACHERS!
HSLDA will fix that eventually. A range of educational curricula that exceed the standards of any public school are available online. Most states do not (and should not) attempt to control a home curriculum. The students do better than their peers anyway.
I am glad that your children are doing so well. You must be doing a good job. However, thank a TEACHER for your ability to do this!!!
Equine feces. According to you, I couldn't be doing a good job because I am not trained to do it. As it is, I spend less time teaching my kids now than I did when they were going to school, in part because I don't have to deal with the problems the school induced. I spent a good part of the first two years of home schooling my younger daughter UNDOING THE DAMAGE done by a private school implementing some modern wack-job theory of learning how to write (one of the reasons we started teaching them at home). I didn't have to teach my older daughter calculus (although I am qualified to do so); she did it herself and was recommended for college level physics by a university professor simply by presenting her work. She was twelve at the time. From that you should get a clue regarding what home education is all about: It is not taught; it is learned.
My kids also study material I never had the opportunity to read: Tacitus, Cicero, Plutarch, Julius Caesar, Homer, Herodotus... It would be impossible for me to "teach" them that information. Instead, I (mercilessly) criticize their writing derived from that material and make certain that they can support a reasoned argument with citations. Thus, I could not be "certified" to teach the material, but they are getting a great education.
