Are California Schools the Worst in the Nation?

Bob Somerby is wondering if it’s really true that California schools used to be the nation’s best and then, after Prop 13 passed in 1978, quickly plummeted to become the nation’s worst. Objectively, that’s all but impossible to measure since we don’t have much in the way of testing statistics to look at before 1978. What we do have are some overall statistics on how schools are managed. For example, here are three key metrics from 1970-2015:

Generally speaking, California got worse compared to the national average on all three metrics between 1970 and 1995. Teacher salaries continued to get worse through 2015, but per-pupil spending and student-teacher ratio stayed flat.

So what did that do to test scores? Between 1970 and 1995, who knows? Between 1995 and 2015 they went up significantly, but so did test scores for the whole country. We need to set the bar a little higher and take a look at California test scores compared to the national average:

What does this tell us? Not a lot, since we’d really like to see how California compared to the national average in 1970, before Prop 13 was passed. However, it does tell us something: over the past 20 years, pretty much every ethnic group in both reading and math has made progress compared to the national average. What’s more, California’s test scores in 2017 ranged from about 98 percent to 101 percent of the national average. That’s not going to win any awards, but it hardly suggests that California schools have collapsed into a dystopian hellscape. Roughly speaking, there’s the usual mix of good ones and bad ones, and overall they’re about average.

A BETTER WAY TO DO THIS?

We have an ambitious $350,000 online fundraising goal this month and we can't afford to come up short. But when a reader recently asked how being a nonprofit makes Mother Jones different from other news organizations, we realized we needed to lay this out better: Because "in absolutely every way" is essentially the answer.

So we tried to explain why your year-end donations are so essential, and we'd like your help refining our pitch about what make Mother Jones valuable and worth reading to you.

We'd also like your support of our journalism with a year-end donation if you can right now—all online gifts will be doubled until we hit our $350,000 goal thanks to an incredibly generous donor's matching gift pledge.
