Looking further into the SOL pass rates, here are the reading data for Richmond’s elementary schools by year:
That graph is much too complicated but it does contain all the data, plus the Richmond average. Also, the graph does illuminate the disastrous effect of the new tests in 2013 and the relative abilities of some schools to weather the change (notably Carver(!), Munford, and Fox, and, with a different pattern, Fairfield) and the gross failures of others (notable Mason, Oak Grove, and Woodville). Doubtless this tells us a lot about the principals of those schools, especially in light of the more challenging student populations at Carver and Fairfield.
Focusing on the high and low performers, plus our neighborhood school (with the State average for grades 3-5 added) gives a more readable picture.
The math scores paint a similar picture, except that the Big Hit from the new tests came a year earlier.
