DISD had enjoyed more than a decade, from 2000 to 2012, of low teacher turnover. Since major student achievement is usually delayed a year following major changes, the consistent lowering of the Texas/DISD Achievement Gap went from 2000 to 2013! The Gap went from 20 percentage points in 2000 to only 8 by 2013!
Then progress went backwards big-time in 2013/14 as preparations for TEI were made with the record high of 43 failing DISD schools! That disaster was accompanied, naturally, by and an exploding Texas/DISD Achievement Gap. DISD lost 5 years of Achievement Gap progress in 2013/14 with the Gap going back up to 11 points again, to the old 2009 Gap! Teacher turnover exploded in 2012 and was over 21% by 2013! Teacher turnover has stayed higher than any year on record prior to 2012, ever since!
Study the chart below. All data on this chart comes from the Texas Education Agency web site, Snapshot, or from the Dallas ISD Data Portal, as collected over the years. Sadly some of the older DISD data is no longer online. Why? Does someone want to stop multi-year comparisons like this of progress?
Dallas ISD did not recover academic progress, back down to an 8 percentage point Gap, until 2016/17. Teacher turnover remains at record levels! Before 2012 DISD teacher turnover averaged
2.8 percentage points LOWER/BETTER than Texas statewide. Since 2013 DISD teacher turnover has averaged 3.7 percentage points WORSE/HIGHER than Texas! Is that an accident?
Who is trying to destroy Dallas ISD?
Is there a profit motive somewhere?
Or were politicians threatened by an increasingly well educated core of critically thinking students who would vote? It is no accident that Texas has one of the lowest per student education investments in the nation. Such low education investment is related to low voter turnout nationwide. Only Hawaii & West Virginia had lower voter turnout in November 2016 than Texas!
Or is it all of the above?
