Comprehensive teacher evaluation

This paper proposes a comprehensive evaluation of teachers due to the condition of randomness that has the longitudinal behavior of the average teacher evaluation by students to one teacher in the same subject in a span of seven years and 21 teaching periods. This average has a random behavior, observing 22 cases of teachers who have served at least fifteen consecutive groups, at different times to the same subject and the same profile of students. In this way it is intended to eliminate the multifactorial influence that others have found in the evaluation of teachers as would be gender, age, experience and knowledge of teachers, as well as the level, content, duration, activities and tasks proposed in the course. The possibility that the condition of teaching performance is an inherent quality and transferable to another scenario is also explored, which is studied by comparing the average obtained equality assessments same teacher in two different courses taught during the same period. And finally it looks like more influence on the averaging and reliability of the instrument used is studied.
