One of Jeb Bush’s signature initiatives–and possibly the stupidest–was giving schools letter grades of A-F.

Schools are complex institutions with many individuals engaged in their work, some doing better jobs than others, some essential, some not. No complex institution should be graded A-F. No individual child should be graded with a single letter, A-F. Imagine if your child came home with a report card that held only one letter, A-F. As a parent, you would be outraged. You would know that she was good at this, not so good at that, that there were many ways of describing her efforts and abilities and skills and work. How dumb it is to grade an entire school with a single letter.

Yet the Florida model of testing, accountability, choice, punishments, and rewards goes wherever there are rightwing zealots who want to destroy public education.

New Mexico had the misfortune of electing a Republican governor who wanted to be just like Jeb. She hired a non-educator, Hannah Skandera, as the state’s commissioner of education (Skandera had worked for Jeb), and she tried to import the Florida model. After seven years, Skandera left, and New Mexico saw zero improvement in education by any metric.

Fortunately Susana Martinez was replaced by a Democratic governor, former Congresswoman Michelle Lujan Grisham, who has been removing every trace of the Florida model. In January she eliminated the state’s disastrous teacher-evaluation system and the hated PARCC tests, which had been imposed by Martinez’s executive orders.

Yesterday, with the stroke of a pen, she repealed the state’s A-F grading system. The state’s Public Education Department must now devise a new accountability system to comply with the federal Every Student Succeeds Act. The bill now under consideration in the legislature calls for a “dashboard showing how each of the state’s public schools are faring in terms of graduation rates, student proficiency outcomes, reliance on federal Title I funds and the progress of English-language learners.”

Of course, this too appeals to the idea that parents are consumers, not citizens bound to work together for better public schools.

New Mexico has extremely high levels of child poverty, the second worst in the nation after Mississippi. Standards, accountability, and choice doesn’t cure that. It also ranks at the very bottom of NAEP, close to the other poor states. The Florida Model pretends that poverty doesn’t matter. Skandera’s failure proved that it does.

The state currently grades schools on a complex range of measures, including graduation rates, student performance on standardized tests, student attendance and parental involvement in schools. Advocates believe these grades provide a clear picture of how schools are performing and encourage communities to help struggling schools. Critics say the formula is so confusing that the grades are of little use. They also complain that the system relies too much on standardized test scores.

Several years ago, a group of Los Alamos National Laboratory scientists said even they struggled to make sense of the complicated grading system.
