The easiest way to raise average test scores in a class or a school is to eliminate the ones who present problems: those requiring special education services, recent immigrants with little English ability and little education in their home country, and so on. If you eliminate the students who are often difficult to teach and who tend to have low scores, then you can look like a winner, because your average scores will rise — and those of your “competitors’ will fall. Without doing anything about our national problems.
(Ain’t educational competition grand?)
Judging by what the for-profit Tesseract/EAI company did in Baltimore back in the first half of the 1990’s, when they were awarded a contract to run seven elementary schools, it looks like they may have done just that. (But their scores STILL weren’t anything to brag about!).
Why do I bring this up? Because recently-departed Chancellor of DC Public Schools, Michelle Rhee, supposedly performed various miracles in one of those Tesseract schools, starting in 1992-1993 and going through SY 1994-5. The name of the school? Harlem Park.
See for yourself:
As you can see, the percentage of students eligible for Level 4 special education services in the two official comparison groups of regular public schools, grades 1-5, stayed pretty constant during the entire 4-year experiment: somewhere between 6% and 8% of their students were identified as Level 4 special education.
Not so in the seven Tesseract schools, though. The percentage for the entire group of EAI schools went from 8% SPED to 2% SPED, which means that the proportion of students in those schools eligible for special education services dropped by three-fourths!!!
At Harlem Park, too, the proportion of students in special education during that time period dropped drastically – by 70%.
Did this weeding-out of Special Education students have anything to do with Chancellor Rhee’s alleged miracle? (remember: she claimed on her official resume that she
“[t]aught in Harlem Park Community School, one of the lowest-performing elementary schools in Baltimore City, effecting significant measurable gains in student achievement. Over a two-year period, moved students scoring on average at the 13th percentile on national standardized tests to 90% of students scoring at the 90th percentile or higher.“) [emphasis added by GFB]
Stay tuned for more results.
