This is apparently about 4th, 5th, and 6th graders in an already steadily demising program run at limited schools in the area....but anyway. The real question is what these numbers reveal:
The program was open to all students in the Boston Public Schools who took a test known as Terra Nova in the third grade and received a high score. Those students were placed in a lottery conducted by the central administration office, and lottery winners received letters inviting them to apply to the program. Last fall, 453 students received invitations, 143 students applied and 116 enrolled this year, officials said.
As long as:
1) nothing about the lottery, invitation, or opt-in process was discriminatory;
2) class sizes weren't disproportionally limiting access to minority applicants; and
3) a disproportionate amount of money wasn't being spent on the program such that it harmed the other kids' education
Then citing racial inequities is stupid and counter-productive.
IF there's a correlation between socioeconomic status and race along the same lines in the community that complicates the analysis a bit.
