Also, inquiring minds note the sleight of hand that redefines the cohort by looking at kids who stay enrolled K-8. This eliminates all the lottery winners who were weeded out and/or had needs the charters were unable or unwilling to address.

1- Hoxby is a very controversial figure , a conservative economist, who has been accused of skewing her analyses before to benefit the notion of vouchers and charters. See this controversy sparked by her pro-voucher study of school quality based on whether they were near "streams": http://www.thecrims
2- One of the prime advantages of most charters, if they do indeed show better results, is their smaller classes. In NYC, this results from the fact that DOE has allowed them to cap enrollment and class size at far lower levels than most regular public schools in NYC.
3- it is difficult if not impossible to figure out how much of the advantage at charter schools, in addition to smaller class size, might be due to "peer effects"; ie charter school students are surrounded by other students from more motivated families, who know they can be kicked out at any sign of slacking off or disciplinary trouble. This is certainly not the case in regular public schools; where the students who "lose" the charter school lotteries are surrounded by students from less motivated households, who are also less afraid of being forced out of school for bad behavior or poor performance.
Thus, whether the entire comparison is fair is quite debatable.

Study Shows Better Scores for Charter School Students
New York Times
Students who entered lotteries and won spots in New York City charter schools performed better on state exams than students who entered the same lotteries but did not secure charter school seats, according to a study by a Stanford University economist being released Tuesday.
Charter schools, which are privately run but publicly financed, have been faring well on standardized tests in recent years. But skeptics have discounted their success by accusing them of “creaming” the best students, saying that the most motivated students and engaged parents are the ones who apply for the spots.
