Leonie Haimson of Class Size Matters explains here in shocking detail how charter co-locations harm New York City’s neediest children.

Here is a sample:

“These proposals will uniformly disadvantage the children in the existing schools, cause even more overcrowding and larger classes, and push disabled students out of the spaces they need for special services.

Some of the examples have been described in newspaper accounts. Here is how the severely disabled children in the Mickey Mantle School in PS 149 have already been affected by the co-location of Harlem Success Academy in their building, according to Juan Gonzalez of the Daily News:

Originally, these children had a “cafeteria, playground, library, and cluster rooms (for specialized activities).” In 2006, when the charter school moved in, they lost their library and a bunch of classrooms. The following year, according to a teacher,
“We lost our technology room, our music room, our art room and we had to start sharing the cafeteria, the gym and playground,” Manuell says.

Now she is “teaching theater at Mickey Mantle in a former office with no windows. A fellow teacher conducts four periods a week of gym in a regular classroom because so little time has been allotted in the main gym to the Mickey Mantle pupils”

Now DOE wants to give space to up to “375 middle-school pupils to Manuell’s school over the next several years. They will come from another Moskowitz school, Harlem Success 4.

As for the Mickey Mantle School, 20% of its enrollment will be cut and displaced elsewhere. “Even with that reduction, officials concede the building may reach 130% of capacity.”

Of the 23 proposals to be voted on today, there are 21 co-location proposals and two expansions. Ten of the 23 co-location proposals will cause a building utilization rate of over 100% in the next few years, according to the DOE.

As the DOE severely underestimates the amount of overcrowding in these buildings, one can assume that even more schools will lose their art rooms, libraries, science labs, and intervention spaces, and will suffer class size increases as a result.

Simple justice says this is wrong. Why should we have two publicly-funded school systems, one free to select students and kick them out; the other require to accept all?
