These discussion assumes all these top 7% kids:

1. will apply;
2. will go.

"But both Kealing and LASA changed their admissions processes going into the current school year, and for the first time considered factors such as race, socioeconomic status or the neighborhood where a student lives. Preliminary admissions numbers for 2018-19 show the schools will maintain the gains, or slightly increase, but again, fall short of diversity goals.

“They’ve showed some improvement, but not nearly sufficient enough improvement given the demographics of the district,” said school board member Ted Gordon, who represents the areas of East and Northeast Austin where both schools are located."
