In 2013, the state suspended the Academic Performance Index. This was how many parents judged how their kids' schools stacked up among other schools across the state. Three years later, there still isn't a replacement for the API, even as the state says it's working on a new one. All of this has struck a nerve with Zócalo Public Square Columnist Joe Matthews, who says it keeps parents in the dark and makes schools unaccountable for their progress -- or lack of progress.
