School Grades For School Grades' Sake

Matthew DiCarlo:

I have reviewed, albeit superficially, the test-based components of several states' school rating systems (e.g., OH, FL, NYC, LA, CO), with a particular focus on the degree to which they are actually measuring student performance (how highly students score), rather than school effectiveness per se (whether students are making progress). Both types of measures have a role to play in accountability systems, even if they are often confused or conflated, resulting in widespread misinterpretation of what the final ratings actually mean, and many state systems' failure to tailor interventions to the indicators being used.

One aspect of these systems that I rarely discuss is the possibility that the ratings systems are an end in themselves. That is, the idea that public ratings, no matter how they are constructed, provide an incentive for schools to get better. From this perspective, even if the ratings are misinterpreted or imprecise, they might still "work."*
