Yes, I remember reading in my local news that several teachers in our school district were teaching full time (permanent district employee) without a teaching license. And apparently there was one middle school teacher teaching some class she had no background in. Turned out that according to a grassroots watchdog group consisting of concerned teachers and parents that these wastes of space were friends and family of district central office. Really galling considering that my state requires state exams including a content exam, student teaching semester, so many clinical hours, and grad school which requires the GRE.
So, yeah... all of you who said putting your kids in public school is abuse by proxy are one hundred percent correct. When you're not dodging the kid fucker pervert teachers, you have to deal with the sociopaths, pavement apes using non-words like "conversate," and outright bullies, you get...shit like this.
