Part Ten of Many
Installment #10 in our lengthy saga of failures by the current and past Chancellors of the District of Columbia School system.
Today we look at overall proficiency rates in elementary and secondary math and reading on the DC-CAS for 2010 and 2011, which will add up to eight separate goals out of our grand total of 78.
(Up until now, out of 38 goals assessed, the dynamic duo of Rhee and Henderson managed to attain one and a half of them.)
Here is the summary table:
In this set of goals, a high number is good, because it means a higher proportion of students are ‘proficient’. Unfortunately for Rhee, Henderson and the various billionaire foundations, not a single one of these targets were met.
In every single case, the ‘target’ was higher than the actual proficiency rate — and in some cases, the proficiecy rates actually declined a bit from 2010 to 2011, despite all the rosy predictions…
For example: in 2010, the promise was that 53.0% of all DCPS elementary students would be ‘proficient’ or ‘advanced’ on the DC-CAS in math. In reality, only 42.8% of our elementary kids met that standard. In 2011, the prediction was that 58% of all DCPS elementary students would be proficient or advanced in math on the DC-CAS, but in fact, only 41.8% were — and that was a decline of about 1% from the year before.
And the same sort of thing happened in every one of the eight categories measured here. In every single case, the predicted target was considerably higher than the actual result.
So with eight more failures out of eight more measurements, the total now is 44.5 failures and 1.5 successes, which is beyond pitiful: about THREE PERCENT success and 97% FAILURE.
Again, why does Kaya Henderson still have a job?
And why didn’t these four foundations ask for their money back?
My next task needs to be to investigate the results for 2012 and 2013, which will be a bit challenging because DCPS and OSSE completely changed the way data are reported. The new way looks all fun and interactive but — in my opinion — is a lot harder to extract actual information from. It might take me a couple of days.
The saga so far:

Once again, let me credit my colleague Erich Martel for coming up with the idea of going back to the original promises and seeing if they were kept or not, and sharing his findings with me. These calculations are generally my own, so if you find any mistakes, don’t blame him. Blame me.
