The Dual-Language Pipeline: How Bilingual Schools Became the Hottest Real Estate in Brooklyn

You’ll see them if you stroll down Smith Street on a weekday morning: strollers arranged like a small fleet outside P.S. 58, parents holding iced coffees while wearing exercise gear, and the occasional father still on a Zoom call. Situated in Carroll Gardens, the school offers one of the most popular French dual-immersion courses in the city. Over the last ten years, homes in its zone have added an odd new line item to their listings. Everyone knows, even though realtors don’t always express it aloud. The cost includes the school.

The emergence of bilingual schools may have quietly moved more money than any other trend in education in New York. What began as a civil rights initiative in the 1960s—programs designed to prevent Latino and immigrant children from losing their native tongue while learning English—has been drastically altered. One principal in Washington, D.C., put it bluntly: “Dual-language has become sexy.” And sexy means pricey in Brooklyn.

It’s difficult to miss the pattern. A school launches an immersion program in Spanish, Mandarin, or French. The demographics change in a matter of years. In the catchment zone, white, professional families who may have previously fled to the suburbs or private schools begin purchasing brownstones, sometimes paying several hundred thousand dollars more for the ideal address. There are hundreds of people on the waitlists. The majority of families who speak Spanish as their first language never succeed.

This tension has been discussed for years by Marie Bouteillon, who started the first French dual-immersion program at P.S. 58 and has seen the model spread throughout Brooklyn. Integration—English speakers and multilingual learners studying side by side and both groups graduating bilingual—was the initial promise of these programs.

The catchment zones hardly ever work together in reality. For children who already have everything, a program in a wealthy neighborhood effectively becomes an enrichment track for foreign languages. When there are no peers who speak English well, a program in a working-class neighborhood turns into a one-way developmental classroom.

It’s difficult to ignore a recurring pattern when observing this from a distance. Families that used to steer clear of New York City public schools are now actively vying for spots in them, but only in specific ones that teach particular languages in specific zip codes. Bengali and Haitian Creole do not, for some reason, move real estate in the same ways as Mandarin and French. It’s still unclear exactly what that gap says.

The imbalance has been documented for years by CUNY researchers. Enrollment of multilingual learners in dual-language programs has hardly changed despite the growth of the programs. Under pressure to boost test scores and fill seats, principals occasionally use a new bilingual strand as a sort of demographic reset button to attract more affluent families and stifle discussions about a school’s reputation. It functions. The structures fill up. More money is raised by the PTAs. They repaint the brownstones.

Teachers, parents, and advocates continue to resist the drift. Some districts have started limiting class sizes, extending immersion into middle school, and allocating seats for native speakers. It is genuinely unclear if any of it will be sufficient to restore the original mission. For the time being, Brooklyn continues to do what she does. The strollers form a line. The signs appear in one window after another. bilingual. bilingual. “Hablamos aquí.” And the price increases once more when a different listing down the block subtly adds a sentence about the school zone.
