Dallas ISD Progress 2000 to 2013, then it stopped!

Anyone who thinks the progress in Dallas ISD only started in 2012 is ignoring the data! That is the year the progress began a painful and rapid stop! DISD had more than a decade, 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 by 2013/14 with the record high of 43 failing
schools! That disaster was accompanied, naturally, by and an exploding Texas/DISD Achievement Gap. DISD lost 5 years of 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 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?

School Time Capsule Postmaster Research Proposals

The indications for progress through the volunteer work of School Time Capsule Postmasters is significant.  These volunteers help students plan their own futures in writing every year, and explore their family histories with new information from elderly relatives every year. This process improves the self image of students.  They take charge of their own lives.

Teen pregnancies go down, negative behaviors decrease, and academic performance improves.  High school graduation rate soar.

In child welfare terms, the number of referrals from the area of town with schools using the volunteer work of postmasters, goes down.

This pattern must be verified in by research.  If a funded project were to start School Time Capsule Projects in every elementary and secondary school in two of the highest child welfare referral feeder patterns belonging to two high schools in a high poverty urban area, these hypotheses could be well tested within 5 years.

See blog postings below but most especially at to see what is being proposed by better understanding the School Time Capsule Project and the work of a postmaster.

This is a very quick first draft.  This posting will be worked on.

The 2 Dallas ISD high schools in 2012 to beat Highland Park High School became 9 in 2019!

2012 to 2019 the 36 established Dallas ISD high schools improved wonderfully! These three charts are a study based on the percentage of students in each school who met TEA standards each year in each school from 2012 to 2019. There are three charts with the same information in each chart but sorted by different data. All charts include the percentages for Highland Park High School, the most affluent high school in all of Dallas County. It is also the only high school in Dallas County with no children living in poverty. It is included to give some comparison as to the poverty gaps that are being made smaller by our public schools! In 2012 only 2 DISD schools had higher percentages of students meeting standard than Highland Park High School. By 2019 that number had grown from 2 to 9 schools. They also did it with average poverty rates above 67%.
The first chart is of Dallas ISD High Schools ordered by improvement 2012 to 2019. The second chart is ordered by improvement in 2019 alone. The third chart is sorted from the largest enrollment high school down to smallest.
Schools in the top 12 schools in both of the first two lists are the best of the best, unless they are like Townview Science and Engineering that was already at 93% in 2012, definitely the best! Can't go higher than 100%, so it is lower on the second list.
Gilliam and Garza did exceptionally well in both Top Twelve lists! They also have the highest poverty levels among the schools on both lists. Such success must spread!
First Chart: Dallas ISD High Schools ordered by improvement 2012 to 2019.
This second list is ordered by the 2019 achievement, a more absolute standing of the schools currently.  In 2019 Dallas ISD had 9 high schools with higher percentages of students meeting standards than Highland Park High School. In 2012 only two Dallas ISD high schools had higher percentages than Highland Park.
This second list has all schools listed by 2019 achievement only.
This third and final list is in order by 2019 student enrollment:

There are many ways to look at this data.  This is only the tip of the iceberg, but it indicates tremendous progress by Dallas ISD!

Lancaster ISD as most improved, 2012 to 2019, of 14 ISD's in Dallas County

The chart below lists the 14 largest ISD's in Dallas County as of 2019. Using Texas Education Agency meeting standards data from 2012 through 2019 it shows the 7 year gain in the percentage of students meeting standard for each district each year.  This data was found on the Commit Database at
Notice that, with a 7 year gain of 24 percentage points, Lancaster ISD has the highest percentage gain of any Dallas County school district!  Dallas ISD is second place with 18 percentage points.  Coppell and Irving are tied for third and fourth with 17 percentage points gain each.  Fifth is Grand Prairie with 14 percentage points gain.

Dallas ISD 36 established high schools and progress 2012 through 2019

As of 2019 Dallas ISD has a total of 36 established high schools. 22 are comprehensive neighborhood high schools serving a specific feeder pattern.  The remaining 14 are magnet schools of different types and Early College High Schools serving various areas of interest.  Here they all are on a list with the percentage of students meeting TEA standards each year from 2012 through 2019.

Multiple conclusions are indicated with this data. Notice Trini Garza ECHS has the highest performing of all but 2 high schools, and those two average a percentage of non-handicapped by poverty students that is four times larger than that percentage of non-handicapped students at Garza ECHS.

Dallas ISD Annual Racial Equity Spreadsheet History Missing

Wonderful progress is anticipated in racial equity due to the strong changes in keeping Dallas ISD Magnets first for Dallas students. These changes were covered in the Dallas Morning News on 8-1-19 in the article titled "Here's Dallas ISD's new plan to stop suburban cheaters from stealing magnet school spots."

This is a major move toward racial equity.  Now for DISD to release decades worth of annual racial equity spreadsheets.

Each spreadsheet would cover one school year's worth of data for Dallas ISD schools.  The base for each spreadsheet would be the School Information File format found in the Dallas ISD Data Portal. See

It would expand this demographic and achievement information for each school in a row for each school.  It would add many more variables including the 32 financial variables per school showing moneys allocated by school as reported in the PEIMS Financial Reports.

A decade of such reports will expose massive supplantation of resoures away from high poverty minority schools inside Dallas ISD. Such transparency would allow DISD to develop a truly effective data-driven Racial Equity Program!  Dallas would lead the nation!

Justin Henry and Ben Mackey, could you help such annual Racial Equity Spreadsheets, covering each year of the past decade, to be made public?  We need such a foundation for a truly data-driven racial equity program within Dallas ISD.
