Gary Rubinstein saw an article in Rupert Murdoch’s New York Post claiming that 100% of the 98 students in the graduating class of Success Academy’s high school had been accepted into college.

Based on Success Academy’s long history of high attrition, he knew this claim was likely false.

So he checked and his hunch was right.

He asked:

Is 98 really all the students in the class of 2020?

The answer, of course is, ‘no.’ What the actual number is depends on how you define the class of 2020.

If you go back to a New York Post editorial from just six months ago, it begins with the sentence “Seniors at the Success Academy HS of the Liberal Arts just got their SAT scores — and all 114 did great, with an average score of 1268, 200 points above the national average.” So six months ago there were 114 seniors, which is 16 more than the 98 that are now called the ‘entire’ senior class. For Success Academy to lose roughly one-seventh of the students who were in the senior class just six months ago is stunning. These 16 students had been at the school since at least 3rd grade. Where did those 16 students go?

But if you look further back to the state data, you will find that the class of 2020 had 146 eleventh graders for the 2018-2019 school year. This means that they lost about 1/3 of the class of 2020 between then and now….

If you go back two more years to see where the class of 2020 was when they were in 9th grade you find that there were 191 students in the cohort back then. Also notice that when they were in 9th grade the boy/girl split of the 191 was about 50%/50% while when they were in 11th grade the boy/girl split of the 146 was 44%/56% in favor of the girls. We will have to wait until the official data comes out next year to see what the split was for the ‘entire’ 98 who graduated.

Rubinstein looks at the numbers all the way back to kindergarten and finds that only 28% of those who started Eva Moskowitz’s celebrated Success Academy made it to high school graduation. Way different than 100%.

Another great “success” for skimming, exclusion, and attrition.

Another landmark in the history of charter hype.
