Some awfully big schools
See the list of the largest high schools in New York City, using ‘data’ from the NYC Department of Education’s new class size report?
Brooklyn Tech, 19601? That’s the school’s population, according to the new report. I’ve listed the top 40, below, and there’s more surprises. Each school is listed at 2, 3, 4 times its actual size.
No, Brooklyn Tech has not moved to Reading, PA 19601
Yes, these numbers make no sense. Is there anyone left at Tweed who knows anything, anything at all, about the school system? No one with any actual experience looked and said, um, we don’t have schools with 20,000 kids?

(Brooklyn Tech’s actual register is a bit under 4500)

Did you just add up the “total register” for every class or something? Of course that’s going to give you a number way larger than the actual register, because students take more than one class.
“Did you just add up the “total register” for every class or something? ”
It looks like you haven’t opened the reports. There is a “total register as of 12/7/07 column,” and that is where the ridiculous numbers are.
I sorted them, cut and pasted.
