Sources & Methodology

Primary Data Sources

3rd Grade Reading and Algebra 1

Definition:  This is the percent of students in a given subject, grade, and demographic that pass the 3rd grade reading and Algebra 1 End of Course exam at the Meets grade level standard. If on any given test, there are less than 5 test takers, the data will be suppressed in accordance with FERPA standards. Therefore, the sum of campus data will not perfectly match district data due to this suppression.

High School Graduates

Definition:  The percent of students who graduated from high school in 2017, 4 year longitudinal all rate.

College Enrollment

Definition: The percent of students who graduated from high school in 2017 and enrolled in a postsecondary institution within one year after graduation.

Specific Methods for Mapping Data to Legislative District

Since most education data is not currently available by Texas Legislative Districts, Commit has used specific methodology to aggregate data to Legislative Districts.  There are 2 primary ways we have done that, depending on the level of availability of the data:

Campus-level Data to Legislative Districts

All campus-level data is pulled from the master TEA reference file (, then mapped onto legislative districts using geospatial analysis. Schools missing an address in the TEA reference file would be missing from the count.  

We have also found errors in the zip codes that TEA provides, making a campus appear in a different area than it truly is located. We at Commit have done our best to address these errors as we find them and update our records.  If you find an error, please report this to Commit using this link or the feedback form below so we can update our school address file.

County-Level Data to Legislative District

Some data (ex: THECB) is only available at the county level.  There are multiple ways to map county level data to legislative districts, but none are 100% accurate since counties do not line up to legislative districts. The method used in this analysis was assigning the county with the largest number of campuses within the legislative district to that district. Therefore, counties could be counted twice for two different legislators and should not be added to find the state of Texas total.

Ex: A legislative district has campuses in both Dallas and Tarrant counties.  The majority of those campuses, however, are in Dallas County. Therefore, this legislative district would show only Dallas County data for any county-level data.  Tarrant County data would not be included in these numbers. This also means that if the majority of multiple legislative districts are in Dallas County, those legislative districts may have matching data.  If you would like the full county by county breakdown or additional information, please fill out the Data Request Form and we would be more than happy to provide you with additional data.
