anti Teacher-Dictatorship Board

eventhough many teachers are hardworking people, some are jaded, currupted, or plain clueless to the degree that cancels out what benifit schools might provide to kids. the current teacher evaluation system is no where adequate, only sending one observer a year(or so) to a class. I propose that members of PTA, or better yet parents who have the time/effort to oversee ther own children do so on a regular basis (twice a week?). they would have an official organization that is recognized and respected by the school administration. these observers would serve as check for some teacher's almost-dictatorial power over the student, much like the check-and-balance property of US gov. Sadly,ether students by themselves are too naiive to detect such bullshit, or when they are able to, the students' just opinions/objections are dismissed along with petty whine of other students'.
