Texas Smart Schools
While there are a number of methods used to measure school district performance, one such measure is the "Apples to Apples" website produced by Texas Smart Schools.
The website www.TXSmartSchools.org rates Texas school districts by academic achievement and annual spending per student.
For the second year, Keller ISD has been awarded the highest score – five stars – for being a "Very Low Spender" and rating "Very High" for academic achievement. Keller ISD is in the bottom 20 percent in per pupil spending and in the top 15 percent academically.
