Value-Added Scores: The Truth Behind the Numbers


           The title of this blog post would lead one to believe that I am in support of an evaluation method that utilizes student test scores. This is definitely not the case. People in favor of these value-added scores will try to defend their opinion by saying that the ratings are based on a student’s progress and not just the base score. This begs the question, how can one compare the concepts learned in a 7th grade math class to those learned in an 8th grade math class when the material is much more challenging? A team of fifth grade teachers in New York is currently experiencing the lack of truth behind their evaluation ratings in which 40% was determined by student standardized test scores.
            The Principal at Public School 146 describes her fifth grade team as a group of hard-working, talented teachers that are dedicated to student achievement (staying until 7 pm on many Friday evenings). From winning a Fulbright scholarship to working as an Archaeologist in France, this team of teachers has a variety of backgrounds that would be impressive for college professors. After pushing 96% of their fifth graders to proficiency in English and 89% for math, one would think that these teachers would have some of the highest ratings in the state. This is not the case. This team of teachers had value-added scores that ranged from 1 to 11, all out of 100. One of the reasons for these low ratings is the fact that 97% of the students were proficient in math as fourth graders. After briefly reading about these teachers, do you agree with their low ratings?
            Some states have already adopted the use of value-added scores for teacher evaluations. In many cases, strong teachers are getting mediocre evaluations and some who get the highest are just ending up in a good situation. It is imperative that we fight this measure and work to find a better way to evaluate teachers.
