Probably the only reason the ministry does not allow High school students to evaluate teachers is that they do not trust them to be logical enough to evaluate fairly.
Which is true. Kids will definitely vote with their emotions and if reviews are as important as people make them to be, a few teacher's life would be very poor indeed.
I'm saying this because i get to evaluate my lecturers in uni. Suck it up kids, don't be in such a hurry to grow up, and don't think you can think maturely all the time.
