Gary Rubinstein read a story in the local Rupert Murdoch newspaper saluting Eva Moskowitz’s charter chain for its high SAT scores, but then noticed how many students were in the senior class. (Billionaire media mogul Rupert Murdoch is a multimillion-dollar donor to the  Success Academy charter chain.)

What school advertises its SAT scores? Success Academy!

Gary noticed that of the students who started in second grade, nearly 70% did not make it to the senior year.

He writes:

The New York Post recently ran an editorial about the SAT scores of the Success Academy senior class of 2020.  Of all the different numbers they referenced, one that I took note of was 114 — the apparent number of students in the senior class.

The class of 2020 is the third graduating class of Success Academy.  The class of 2018 had 17 seniors out of a cohort of 73 first graders in 2006-2007.  The class of 2019 had 26 seniors out of a cohort of 83 kindergartners in 2006-2007.  Some of the class of 2019 were students who had been held back from the class of 2018 — probably in a comparable number to the number of 2019 students who will graduate this year.  So the 26 out of 83, or 31% persistence rate probably accounts for students who take an extra year to graduate.

For the class of 2020, things get a bit more complicated since in 2008 Success Academy did its first expansion and grew from one school, now called Harlem 1, into four schools now including Harlem 2, Harlem 3, and Harlem 4.  Some of the past records are incomplete for these schools, but when the 2020 cohort was in 2nd grade in 2009-2010, I find that there was a combined 353 students in the cohort.  By 6th grade, they were down to 263 students and by 9th grade it was 191.  In 10th grade they were 161 students and in 11th grade, 146.  And now, according to the New York Post article based on a Success Academy press release, they have 114 seniors.  So only 32% of the students who were there in second grade made it through their program.

Better test scores through attrition, a surefire formula for success!

I have had a long-running exchange with a wealthy pundit who gives six-figure amounts to Success Academy. He says they have found the secret sauce for educating all children in the New York City public schools, and for all schools everywhere. I ask him what should be done about the majority of students they accept who don’t survive. He seems to think they don’t matter. Only the strong survive. Or deserve to survive.
