There are still more than 2,000 spots open at D.C. charter schools for the 2014-2015 school year, but most of the available seats are in low-and mid-performing schools, according to data that the D.C. Public Charter School Board released Thursday.

About 350 of the open spaces are in schools rated high-performing. Such “Tier 1” schools that still have space for students include Achievement Prep, Paul, Washington Mathematics Science and Technology, four campuses of the KIPP DC network and the Chavez Prep campus of the Cesar Chavez network.

The charter board also published waiting-list lengths at each school. There are more than 7,000 students on charter-school waiting lists across the city.

Two Rivers, an expeditionary learning school in the District’s NoMa neighborhood, had a waiting list of more than 1,700 names, the longest among all charters; the second-longest list belongs to Mundo Verde Bilingual, a school specializing in dual-language instruction, sustainability and expeditionary learning.

Waiting lists and open spaces at each grade level and each school are available online here. The charter board plans to update the data regularly over the coming months. Wait lists will begin shifting soon: Today is the deadline for students to enroll in schools to which they won seats in the first round of the citywide school lottery.

Students who did not enter the first round of the lottery, or who entered but did not win a seat, are eligible to enter a second round. The deadline for that round is May 15.
