Gary Rubinstein has been bothered by the lies spread about the college completion rates of charter students. He has pointed out that it is unfair to say that X% of your students in twelfth grade finished college without admitting that twelfth grade is not the right place to begin, since it excludes the attrition that may have occurred earlier.

Among charters, KIPP has been honest in stating that it counts the students who completed eighth grade and persisted to high school graduation. Others say they just can’t find the data to learn when their senior started in their school. Can you believe that?

Gary posts a twitter exchange he had with Richard Whitmire, who clearly did not want to engage with Gary. Whitmire wrote a fawning bio of Michelle Rhee, then a book praising Rocketship Charters. Not a high success rate.

What Gary is looking for is candor, not boasting.

It seems the public is beginning to understand that charter school boasting is built on cherrypicking students and pushing out the ones that get low scores.
