The co-location situation

Do charter schools hurt their neighboring schools? A new study of New York City schools says no — they help.

Far from hurting existing schools, new charter schools in New York City have actually helped their neighbors improve, according to a new study.

The study’s surprising conclusion adds some hard data to a divisive debate: Do the privately operated yet publicly funded institutions sap resources and hurt traditional public schools? Or do they exert competitive pressure that lifts all boats?

The answer, at least in New York City, is that traditional public schools should want to be as close as possible to multiple charter schools, and ideally share a building with one.

The study finds that being closer to a charter school led to small increases in math and reading scores, boosts in reported student engagement and school safety, and fewer students being held back a grade. The test score gains increased slightly more in traditional public schools that are co-located with a charter.

Sarah Cordes, a professor at Temple University and the study’s author, suspects that her findings are the result of the competition stoked by charters.

“I think having that close a proximity might really get administrators to get their act together,” she said. “Part of it is just that it’s really hard to ignore a charter school in your building.”

The peer-reviewed study, set to be published in the journal Education Finance and Policy, is based on student-level data from nearly 900,000 third- through fifth-graders between 1996 and 2010. Cordes’s method takes advantage of the timing of when new charter schools opened to isolate their effect on nearby district schools, using performance before and after the charter opens.

A school within a half-mile of a charter school, for instance, saw significant bumps in math and reading scores — estimates that are boosted with greater numbers of nearby charter schools, and schools from “high quality” charter networks such as Success Academy or KIPP.

Test score bumps at traditional public schools were even more pronounced in cases where they occupied the same buildings as charter schools — an arrangement that has drawn intense criticism from many educators and parents, and which often forces the schools to share resources like cafeteria and gym space.

Cordes’s results are consistent with previous research from other districts, which have typically pointed to either neutral or slightly positive test score effects of charter schools on their neighbors.

The critics get something from the study, too: evidence that existing schools do lose some students when charters open nearby. When a charter was between one-half to one mile from a district school, for instance, the district school tended to lose roughly 16 general education students. But Cordes concluded that the population changes weren’t big enough to influence test scores.

So why do the city’s charter schools boost their neighbors’ performance?

One reason, Cordes says, is that the charter sector is working as it was intended: creating pressure on administrators to improve the quality of their schools.

Based on survey data collected by the city, she found that parents reported significantly higher levels of student engagement, and those with children in co-located schools were less likely to describe their schools as unsafe. Teachers reported higher academic expectations and “more respect and cleanliness” after a nearby charter school opened.

Cordes also points to the budgetary effects of charter schools. Somewhat paradoxically, given charter critics’ arguments, competition from charter schools led to more average spending per student at traditional schools — between 2 percent for schools that are further away to 9 percent for co-located schools.

Though she did not look at whether decreases in enrollment had adverse effects on programming that wouldn’t be measured by reading and math test scores or survey data, Cordes said future research should look at whether enrollment drops lead to smaller class sizes, which have been shown to boost learning.

The New Chancellor

Tell us: What should the new chancellor, Richard Carranza, know about New York City schools?

In a few short weeks, Richard Carranza will take over the nation’s largest school system as chancellor of New York City’s public schools.

Carranza, who has never before worked east of the Mississippi, will have to get up to speed quickly on a new city with unfamiliar challenges. The best people to guide him in this endeavor: New Yorkers who understand the city in its complexity.

So we want to hear from you: What does Carranza need to know about the city, its schools, and you to help him as he gets started April 2. Please fill out the survey below; we’ll collect your responses and share them with our readers and Carranza himself.

The deadline is March 23.

buses or bust?

Mayor Duggan says bus plan encourages cooperation. Detroit school board committee wants more details.

Detroit’s school superintendent is asking for more information about the mayor’s initiative to create a joint bus route for charter and district students after realizing the costs could be higher than the district anticipated.

District Superintendent Nikolai Vitti told a school board subcommittee Friday that he thought the original cost to the district was estimated to be around $25,000 total. Instead, he said it could cost the district roughly between $75,000 and a maximum of $125,000 for their five schools on the loop.

“I think there was a misunderstanding….” Vitti said. “I think this needs a deeper review…The understanding was that it would be $25,000 for all schools. Now, there are ongoing conversations about it being $15,000 to $25,000 for each individual school.”

The bus loop connecting charter and district schools was announced earlier this month by Mayor Mike Duggan as a way to draw kids back from the suburbs.

Duggan’s bus loop proposal is based on one that operates in Denver that would travel a circuit in certain neighborhoods, picking up students on designated street corners and dropping them off at both district and charter schools.

The bus routes — which Duggan said would be funded by philanthropy, the schools and the city — could even service afterschool programs that the schools on the bus route could work together to create.

In concept, the finance committee was not opposed to the idea. But despite two-thirds of the cost being covered and splitting the remaining third with charters, they were worried enough about the increased costs that they voted not to recommend approval of the agreement to the full board.  

Vitti said when he saw the draft plan, the higher price made him question whether the loop would be worth it.

“If it was $25,000, it would be an easier decision,” he said.

To better understand the costs and benefits and to ultimately decide, Vitti said he needs more data, which will take a few weeks. 

Alexis Wiley, Duggan’s chief of staff, said the district’s hesitation was a sign they were performing their due diligence before agreeing to the plan.

“I’m not at all deterred by this,” Wiley said. She said the district, charters, and city officials have met twice, and are “working in the same direction, so that we eliminate as many barriers as we can.”

Duggan told a crowd earlier this month at the State of the City address that the bus loop was an effort to grab the city’s children – some 32,500 – back from suburban schools.

Transportation is often cited as one of the reasons children leave the city’s schools and go to other districts, and charter leaders have said they support the bus loop because they believe it will make it easier for students to attend their schools.

But some board members had doubts that the bus loop would be enough to bring those kids back, and were concerned about giving charters an advantage in their competition against the district to increase enrollment.

“I don’t know if transportation would be why these parents send their kids outside of the district,” Angelique Peterson-Mayberry said. “If we could find out some of the reasons why, it would add to the validity” of implementing the bus loop.

Board member LaMar Lemmons echoed other members’ concerns on the impact of the transportation plan, and said many parents left the district because of the poor quality of schools under emergency management, not transportation.

“All those years in emergency management, that drove parents to seek alternatives, as well as charters,” he said. “I’m hesitant to form an unholy alliance with the charters for something like this.”
