Here’s What I Posted on Michelle Rhee’s Blog at ‘StudentsFirst’

Someone else brought the 1995 study to my attention, and I went through it and tried to pick out the parts that compare the cohorts at Harlem Park when Rhee taught there, to those in other, similar schools. The original 1995 data is here:…

What I discovered is that there is absolutely no evidence whatsoever of Michelle Rhee accomplishing the miracle that she has over and over claimed: raising students from well below the 20th percentile to having over 90 percent of them scoring above the 90th percentile.

As far as I can tell, it looks like there were only about two classes of third graders at Harlem Park during the year 1994-1995, the year that Rhee said that she and her team-mate brought two classes from the very bottom to the very top. And the scores for that third grade cohort at Harlem Park in both reading and math for 1994-1995 appear to be somewhere between the 40th and 55th percentile. At best.

You can also look at my blog,


where I point out the exact pages in that long study where you can look for that information.

Only about 20% to 25% of the students were excluded from having their test scores processed for the study at Tesseract schools, so that doesn’t increase the number of students in the actual classes by very much.

What’s more, I find it extremely interesting and significant that the cohort of students that were in the 2nd grade at Harlem Park appears to have shrunk by nearly 50% by the time they got to the third grade, when Rhee made her so-far-still-unsubstantiated claims of this educational miracle. Exactly how that winnowing out, I can only guess.And my guesses are fueled by my suspicion of Rhee’s notoriously long track record of distorting data.

Care to respond to that, either Michelle Rhee or Mafara Hobson?
