The Stanford Educational Opportunity Project has developed a new data tool called the “Segregation Explorer.” Let’s start with the definition of what is being measured in this data, which stretches from 1991 to 2022:
Segregation estimates in the interactive map represent the two-group normalized exposure index, which measures the difference between two groups’ exposure to one of the groups. For example, the White-Hispanic normalized exposure index compares the proportions of White (or Hispanic, equivalently) students in the average White and Hispanic students’ schools. A White-Hispanic normalized exposure value of 0.5 indicates that the proportion of White students in the average White student’s school is 50 percentage points higher than in the average Hispanic student’s school (ignoring the presence of other groups aside from the racial dyad of interest). For more information on this measure, see our brief.
Okay so bottom line: darker is more segregated, lighter is less segregated. If we take the map back in time as far as it will go (1991) the White-Non-White student exposure index looks like this:

If you are squinting at your phone, New York was the school segregation capital of the United States with a white-non-white exposure index of .62. Fast forward to 2022 and the white-non-white exposure index map looks like:

Thirty-one years later, New York remains the school segregation capital, but at least it went down from .62 to .51.
Choice opponents often claim that choice programs are increasing school segregation. A sadly typical example came in a guest column claiming that school choice had made Arizona school segregation worse than the 1950s and 1960s (!)
Well, school level data from the 1950s is a bit hard to come by, but let’s check the trend in the Stanford Educational Opportunity Index-White-Non-White exposure index trend:

So again if you are squinting at your phone, in 1994 (the year Arizona’s charter and open enrollment laws passed- kicking off the K-12 choice era) the white-non-white index stood at .36 and in 2022 the same measure had dropped to .31- which just happens to be one half of the level of New York in 1991.
The Stanford Educational Opportunity Project also has updated figures for the academic growth of poor students. Let’s see how that worked out for Arizona (1) and New York (2):

Somebody must be benefiting from the $38,000 per student spent in New York’s public school system, it’s a shame that the list does not include the students.
Mexicayotl Academy of Excellence, a charter school in Nogales Arizona, demonstrated the highest level of average academic growth among Arizona schools in the latest version of the Stanford Educational Opportunity Project data (see national data below). Clocking in at an impressive 95.6% faster than the national average, Mexicayotl is famous for academics, native dance performances and fun. It is not just the fortunate students in Nogales who can learn from Mexicayotl- the school has much to teach the rest of us as well.

Former Arizona Superintendent of Public Instruction Lisa Graham Keegan wrote about Mexicayotl and other schools like it for the Fordham Institute. LGK cautioned against technocratic overconfidence- especially in the form of five-year default closure provisions-because it turned out in Arizona that some fantastic authentically community schools might have been closed by such folly:
Moreover, Arizona’s “wild” charter journey led to many low-income, highly performing charter management organizations that can only be found in the Grand Canyon State. Many are community-focused and community-developed, which we all say that we want, but their first priority was on stabilizing the communities they grew from. In other words, they weren't very good academically to start—but they did transform their neighborhoods, and parents trusted these new schools with their precious children over many other options that went out of business due to lack of enrollment.
Years later, many of them, like Academies of Math and Science, Mexicayotl Academy, and Espiritu Schools, are now among the top performing schools in not just the state, but in the country, and were highlighted in last week’s Education Equality Index. The thing is, it took a decade to do that. And we Arizonans let it happen.
A few things for overconfident technocrats to consider: how many Mexicayotl Academies have been closed around the country by five-year default closure provisions in charter laws? What if authentic, community-based schools need a bit more runway than parachuting in a group of TFA kids to whip up math scores with a cat-o-nine tails? What if our methods for judging school quality are still primitive?
Mexicayotl’s parents in the early years, surveying their other options, decided to place their confidence in the school’s staff. Luckily, Arizona’s charter law did not have a default closure provision and also granted 15-year charters. Arizona’s method of accountability (lots of options) is brutally efficient compared to the top-down method, but Mexicayotl survived it.
Indiana recently followed suit in lengthening their charters to 15 years. This will take a considerable administrative burden off the schools rather than having them continually working on renewal. Fortunately, Indiana is also equipped with other options for families with the broadly available voucher law.
Who will be next?
The Florida Legislature is considering expanding open enrollment for public schools and giving students more freedom to cross district boundaries.
What could change if parents are more able to move their children to schools outside their assigned zones? We can draw some insight from Arizona, which has had a statewide open enrollment policy for nearly two decades.
In a nutshell, public schools in the Grand Canyon State have taken more steps to attract students and please parents, by expanding special programs and marketing their schools.
"Open enrollment has really transformed public education in Arizona,” said Kristine Harrington, a spokeswoman for Scottsdale Unified School District in Arizona. The district, she said, has responded to parent demands by creating more International Baccalaureate and magnet school programs, including schools that focus on science and robotics.
Schools near the borders of other districts almost always have long waiting lists, Harrington said. Some of the district's high schools enroll as many as one third of the students from out-of-district addresses.
Florida's school districts have embraced IB and magnet programs. In recent years, they've expanded them, and considered broader open enrollment policies, sometimes while speaking in explicit terms about competing with a growing charter school sector.
In Arizona, the greater freedom of movement among schools may have helped accelerate a similar trend.
“Open enrollment has been very, very popular,” David Garcia told the Arizona Republic. Garcia, an education professor at Arizona State University, said more students use open enrollment to transfer to other public schools than enroll in charter schools. In a state with one of the highest percentages of charter schools in the country, that says something. (more…)
The Shadow FactionDianne Douglas was elected as Arizona’s Superintendent of Public Instruction largely on an anti-Common Core platform. Last week Douglas, a Republican, decided to start her war against Common Core by firing two State Board of Education employees. Arizona Gov. Doug Ducey (a fellow Republican who previously endorsed Douglas) stepped in to stop the firing, arguing that the State Superintendent didn’t have the power to terminate Board of Education employees.

Diane Douglas
Douglas retaliated in a bizarre press release, accusing the governor of supporting “two liberal staff” members of the board and creating "a shadow faction of charter school operators and former state superintendents who support Common Core and moving funds from traditional public schools to charter schools."
Demonstrating the best way to deal with criticism, Lisa Graham Keegan (the alleged ringleader of the shadow faction) decided to respond with humor. According to the Arizona Republic, Keegan “sat up late ordering coffee mugs emblazoned with #shadowfaction.” For supporters, she’s ordered mugs with the words #shadowfactionfan.
The issue gets more bizarre with Douglas, but that is another story.

Dr. Evil, rumored to be a working for the Shadow Faction as a consultant.
Speaking of using humor to address criticism, Matthew Ladner (who was snubbed in Diane Douglas' Shadow Faction press release despite being the senior advisor for policy and research at Gov. Jeb Bush's Foundation for Education Excellence, co-chair of Gov. Ducey's education transition team, and the mastermind behind the concept of Education Savings Accounts that is now sweeping the nation) pens a humorous letter to the Arizona Republic, the state's largest newspaper, which has frequently editorialized against school choice programs.
Ladner points out the obvious: despite the newspapers annual prediction that public schools will be decimated by the school choice movement, public schools in Arizona continue to grow in enrollment. He concludes: (more…)
