Should students evaluate their teacher1

Should students evaluate their teachers?
It is very challenging for me to discuss the matter `should schools
ask students to evaluate their teachers or not`. In my opinion, there
are certain situations which require student`s opinion. But on the
other hand, I believe that it is not necessary for schools to ask
students to evaluate their teachers.
One of the reasons that makes me disagree is that students are not
enough mature to give
`grades` to their teachers. Many students have favorite teachers
therefore, they can hardly ignore their subjective opinion and give a
real evaluation for the practical and theoretical skills to all of their
teachers.
Another reason why I think schools should not ask students to
evaluate teachers is that young people do not have needed
experience for that. Thus, many teachers having a lot of skills and
knowledge can be rated incorrectly.
However, there are certain situations that require students` opinion
for their teachers. Take for instance when some problem occurs
between both sides. In this case it may be very useful for a school
board to regard students` opinion. Some informal anonymous
inquiry asking students about their evaluation and attitude to school
teachers can prevent many further conflicts, for example.
In general, I disagree that schools should ask students to evaluate
their teachers. I believe that young people are immature and
inexperienced to disregard their subjective attitude to some of the
teachers. That is why, if some conflict between students and teachers
appears the measures for resolving it should be delicate because
sooner or later students can become victims of their own prejudice.
