However, many public school teachers do absolutely wonderful work, taking pride in teaching their students well.
If I had to guess I would say 1 in 4? Forgive my terrible grammar btw...:)
I think the odds are much better than that. Even at that ratio, it's not a reason to avoid public schools, not when we know that the bad teachers are concentrated in some schools and the good teachers in others. It's a reason to choose schools carefully if you're not going to homeschool, and to seriously consider homeschooling in certain areas.
Ok, now your tagline is stuck in my head to the tune of Hulk Hogan’s old entrace song.
