You had a bad experience with a teacher and your party delegates marching orders against unions. I get it.
Maybe you are very educated (how did you get there btw?) and a good enough parent to be able to chose your children's educators. Even so, for every compitent parent out there, there are 10 wankers. To suggest that the education system be determined by some of the idiot parents I deal with on a daily basis is scary and irresponsible.
And to those saying its not a free service... Ok, neither is your military, are we going to have citizens grade every officer's performance and make recommendations on who they believe is best fit?
How about our infrastructure? Are we going to be standing behind every civil engineer's back grading his performance?
Teachers went to school to teach. They paid thier dues, got thier qualifications, and perform their duties. Just like you. Not all are fit for the job, just like your occupation. Every field has incompetent workers.
I don't know how the Repub's educational platform expects to remove the human element from teaching though. If you believe anything will, you are sorely mistaken.
