This was in today's The Dallas Morning News under the headline "Richer districts send more kids out of state to college". Also of interest, the article stated that 70 graduates from Highland Park High went to UT-Austin which is a lot considering most students who get into UT-Austin are admitted under the top 8% rule (it might have still been top 10% in the 08-09 school year from when this data is taken). Highland Park sent over 14% of its class to UT-Austin, so many are being admitted outside of the top 10% rule (now top 8%).
