Said another way, when it is easy to "teach to the test" DISD does well. When the testing is on more general abilities and it is harder to "teach to the test" Texas does bad, and DISD does even worse!
That pattern was illustrated painfully with this chart produced by the Dallas Morning News and posted in their 11-7-19 editorial titled "So we are better than Mississippi? Not any more."
There are 12 scores, including all 10 of the Reading scores, that are statistically significant declines.
Finally, here is a summary of the 8th grade African American Reading scores for the nation, Texas, and DISD. DISD is the worst, Texas is better, and the nation is better than Texas.
Creating our own testing system in Texas, that makes us feel good when we teach to the test, is worthless in today's world! This problem is bigger than DISD, but in Dallas ISD students are apparently suffering from it more than anywhere else in Texas. Is that due to TEI, the Teacher Excellence Initiative which started in 2015 when the decline in NAEP scores in DISD appears to have accelerated?
