Right, the biggest schools in NYC, by far, are the best. The smallest public schools in NYC, by far, are the worst. And I assume this trend holds in many big cities and metros overall.

The largest high school in the U.S. by enrollment is Brooklyn Tech, which is always ranked among the top three NYC public high schools. Looking at the list of largest high schools in the U.S., the seven largest high schools in the country are all top-ranked NYC high schools.

Wouldn't be surprised if this is a national trend. Northville High School, in Northville, MI, is arguably the best high school in Michigan. It's also the largest.

Meanwhile, charters, failing public schools, and alternative and special needs schools, all tend to be tiny. So the ranking doesn't make much sense.
