This article is not disclosing the truth or there simply is a lack of information on the author's behalf. CTU is stating that the new teacher evaluation based on the students standardized test scores is not a sufficient reason to rid CPS teachers. The new tactic may be a bit unfair. Poverty, violence, homelessness and amongst other things are a factor. Some kids are facing some social and environmental issues.
