To the editor



The Tribune deserves a D-minus for your April 5 editorial on the new Chicago Public Schools' teacher evaluation plan. You commend CPS for making student standardized test score growth 25 percent of the evaluation but claim that 50 percent would be better.



Tribune Math score, C: There's no evidence that simply doubling a percentage improves the result. In fact, doubling a figure that is considered by experts to be unreliable likely yields no value. The National Academy of Sciences has come out strongly against use of student tests for purposes other than those for which they were designed ΓΆ€” analyzing student, not teacher, strengths and weaknesses.



Tribune Science score, F: You are either unaware of the research or ignore it, both evidence of poor study skills. Further, NAS research shows that student growth numbers are so wildly variant from year to year that their use in judging teachers is neither valid nor fair.



Tribune Civics score, D: You need to review the Constitution, labor law.
