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.

Dallas ISD White Flight through a 50 year lense

Dallas ISD White Flight was actively happening 50 years ago. White families were leaving DISD in increasingly great numbers, but minority enrollment was growing much faster. In 1969/70 DISD was about to celebrate another record high all time enrollment. Dallas prepared for more record growth not knowing 173,799 would become the all time DISD enrollment record for the next half century. White Flight exploded the summer of 1970. Over 10,000 White students left! Could Dallas make more progress by exploring this history with a 50 year lense as it unfolds over the next decade? Sam Tasby, a DISD parent, was about to file a lawsuit in 1970 that would change Dallas more than any parent lawsuit in Dallas History! A DISD school is now named in his honor.
From page 159 of "1874-1966 Education in Dallas" published in 1966.
55 years ago, during the 1964/65 school year, Dallas ISD had what was to become the highest White-non-Hispanic enrollment on record for DISD: 127,124 students. Then White numbers began to decline in 1966, but minority numbers grew faster than the White decline until 1970. 
DISD Administration has rarely been more wrong in an enrollment prediction than 49 years ago, in May and August of 1970. In May 1970 DISD was predicting as many as 180,000 students for the next school year. By August that prediction was down to 177,000 students. The final full enrollment count was only 164,726, over a 9,000 total enrollment loss in one year!  
They had terribly underestimated White Flight! Over 10,000 White students had left Dallas ISD in 1970! 
They were possibly resting on the statement published in 1966 in "1874 - 1966 Education in Dallas" on page 159: "Desegregation of the Dallas Schools was accomplished in the course of ten short years with a minimum of commotion and stress. This may be viewed as just short of miraculous."
Published in 1966. This copy is in Dallas Public Library.
The peace did not last! This 1966 statement in a DISD History book accuraely reflected one viewpoint, but was terribly wrong! White Flight was about to explode! 50 years ago the 1969/70 DISD full enrollment of 173,799 students was to become the largest annual enrollment in DISD History to date. DISD did not know that. 
DISD thought they would continue growing in 1970/71, but then suddenly DISD started to shrink.
The loss of White students was for the first time thousands greater than the increase in minority students that had sustained total DISD enrollment growth since 1965 when White students began to leave.
A new stage of White flight began as DISD full enrollment began to dramatically shrink. That shrinkage continued until total enrollment had lost 46,337 students in just 14 years! The full DISD enrollment of 173,799 in 1970 was down to 127,462 by 1984.  

The summer of 1970 was the highest loss of White students in all 44 years of White Flight, 1965-2009, and in all of DISD History! It was estimated at far over 10,000 students.  

In 1971/72 DISD had the second highest loss as another 8,698 White students left. White Flight continued with thousands leaving annually for three decades, until 2002 when the annual White loss fell to and remained in the hundreds for a total of 8 more years.  
White Flight finally ended in 2009 when White enrollment hit 7,207. From 1964/65 to 2008/09 120,000 White students had left Dallas ISD to achieve the lowest DISD White enrollment in over 120 years in 2009.  
In 2010 White enrollment went up, for the first time in 45 years, to 7,232. That was 45 years after having a White-non-Hispanic student enrollment of 127,124.

Dallas Morning News should allow this discussion of racism.

Would the Dallas Morning News page 3 add on 7-21-19, copied above on the left above, be possible without the Dallas Racist History?

I just sent this letter to the Dallas Morning News.  Do you think we will see it in the paper?
Page 3 of the 7-21-19 Dallas Morning News honored high performing employees from a large Dallas Company. Would such a virtually all White group of employees have been possible without Dallas History? 

Dallas was founded on the work of slaves. After slavery, their descendants were then subjected to 150 years of discrimination. Hispanic families joined them as targets of the Dallas KKK. Dallas became the KKK National Headquarters in the 1920’s. The underfunding of Black and Brown schools has still not ended today in the DFW area!  Transparency is simply not provided to prove otherwise for a reason.

Would this page in the Dallas Morning News on 7-21-19 honoring mostly White employees happen without such a racist DFW History?

Dallas ISD invests more money in teachers of wealthy students!

Following an open records request earlier this school year I received the average teacher salary per school for the three years 2015/16, 2016/17, and 2017/18.  This salary data does not support the claim that more resources are going to the more needy students. The opposite is true! 

In 2015/16 there were 19 schools with economically disabled student percentages below 70%. The difference between those 19 schools and the remaining 216 with higher levels of poverty was $423 in 2015/16. By 2017/18, under TEI, this difference had exploded over 9-fold to $3,953!

Obviously teacher salaries are growning much faster in the schools with below 70% of students living in poverty, and growing more slowly in the most poverty stricken schools. 

Please join with me in studying the average teacher salaries in each school. The new data for 2018/19 should be available by August.

More details about this study, which includes a link to a Googledocs copy of the three years of salary data used as received from Dallas ISD, can be found at

Another study on this data was done focusing on the only three schools (Lakewood and Mockingbird Elementary, and Travis Middle School) with over 50% White-non-Hispanic enrollment. The average teacher salary in these three schools had gone up from 2015/16 to 2017/18 an average of $7,771.  This has resulted in average teacher salaries that are over $9,500 higher than the average of all the other schools in DISD.  The average school in DISD only had an average teacher salary increase 2015/16 to 2017/18 of $3,144.

How can DISD claim that they are focusing more resources on the most needy students?
