What VAM Can Never Measure?
It does not matter how many papers are written discrediting VAM. If it was possible to shove the American Statistical Association Statement on Using Value-Added Models for Educational Assessment in front of Andrew Cuomo’s face, it would make no difference to him. He would toss the paper into his circular file because reason has nothing to do with his so-called reform. VAM is not a rationale, but a belief to the reformers. The basis of their belief has nothing to do with mathematics, but everything to do with the tall tales the reformers give as anecdotal evidence to justify their beliefs.
This tall tale, often told by Teach for America types go something like this. After five weeks of training, this natural born teacher who just graduated from Harvard comes to work in a high needs school and immediately he is able to motivate every student in his 7th grade class located in the most poverty stricken area of Chicago. Each lesson captures the imagination of every student in the classroom. These highly inspirational lessons are differentiated toward every student in his class. He “teaches like a champion” as he was taught in those five magical weeks. He breaks down every academic behavior happening in the classroom. His students never knew that they have to face the teacher, give him direct eye contact, and have their feet planted squarely on floor. For the first time someone told them that they must have pencil in hand ready to write. Not only that, he is at school at 7:00 AM in the morning working with students one-on-one to catch them up to grade level. He tutors individual kids during his prep, during his lunch, and after school until nine at night. On weekends, he spends Saturday and Sunday at a local library working with even more of students. When April comes around, this class now has 100% of his students at level three or four on the Common Core ELA and Math Assessments. Just think, the previous year, when these students had that lazy burned-out unionized teacher who came to school at 8:40 and left exactly at 3:00, only 4% of these students even reached a level two on the assessment. Therefore, this “superman” teacher is rated using VAM as highly effective while that shriveled up union hack next door is deservedly ineffective and must be fired.
