CTA President David A. Sanchez's response to the controversial Los Angeles Times article, Grading the Teacher: Who's Teaching LA's Kids?
"Publishing the database assembled by the LA Times as an accurate measure of teacher effectiveness or even as a 'value-added' assessment model is irresponsible and disrespectful to the hard-working teachers of Los Angeles. This LA Times model oversimplifies what defines an effective teacher and is based solely on one set of student test scores -- tests, I might add, that were never designed to measure teacher effectiveness or even student growth. The California Standards Tests are designed to measure grade-level standards, not student growth from the beginning of the school year to the end of the year. So trying to use that single test to create a value-added model in Los Angeles is impossible. In addition, all education research has concluded that using value-added models as a primary measure for evaluating teachers is not appropriate as the measures are too unstable and too vulnerable. It is impossible to fully separate out the influences of students' other teachers as well as school conditions, classroom assignments, and student attendance. Parents know their child is more than a test score and so are teachers.”
What are your thoughts? How do you feel about the article and what it is proposing?
