My colleague Erich Martel has done it again.
He dug around and found out how the numbers of students who were supposedly “proficient” at Noyes Elementary School (or Educational Center) jumped around crazily from year to year. He was nice enough to put these into color-coded tables so you can watch how the cohorts progress. Here are his tables, which I formatted for viewing on this blog:
Let me try to explain what these charts mean.
The second chart has a diagonal in yellow, representing what I called “cohort L”. In the column labeled “4″ for fourth grade, in the line for the year 2006-7, you see the number 29.6. This means that at Noyes, in Reading on the DCCAS, 29.6% of the fourth grade class was deemed “proficient” or “advanced” based on the marks on the test papers they turned in. The next year (SY 2007-8) , most of those same kids were probably back at Noyes with a different teacher, in the 5th grade. An unknown number of students transferred in or out. That year, the percentage of kids in that group who “passed” the DCCAS in reading fell to 5.6%, a very small percentage of the group. However, the next year when most of them are 6th graders, suddenly an astounding 93.3% of the students are proficient or advanced! That number falls to 57% the next year, and a bit under 40% the following year.
Do you believe and trust those numbers? I sure don’t!
Wherever there was a large jump or fall from one year to the next, Erich wrote the number in bold red.
The actual numbers of students in each grade level was fairly consistent from year to year at Noyes during this period of time. They eventually added a 7th and an 8th grade.
To put this into a little clearer perspective, I took Erich’s data and calculated how many students actually “passed” the DCCAS in math and in reading, and put them in a graph. I hope this is a little easier to follow.
Look at the way those lines jump around!
Real students may be fidgety and jumpy, but their scores on yearly high-stakes tests like this, which many experts say are essentially IQ tests in disguise, do NOT jump around like this. Kids don’t suddenly jump from “Proficient” or “Advanced” to “Basic” or “Below Basic” unless somebody is fiddling with test scores.
It should be obvious to everybody who hasn’t already drunk Michelle Rhee’s Kool-Aid that this is yet more evidence of fraud.
