If you have kids who attend HISD, major decisions will be made Tuesday on the manner in which they are educated.
At stake, seats on the HISD board that could deprive Superintendent Terry Grier of the votes needed to continue his controversial "Apollo" program aimed at improving performance at chronically failing campuses.
"It's really a referendum on reform," said Bob Sanborn of advocacy group Children At Risk.
"We are talking about some trustees who believe things need to change, things need to get better and that we need to have a change agent as superintendent as opposed to others who say 'I don't like change. I want to go back to the old days'. For us, when you go back to the old days and look at the data, it's not very good," added Sanborn who supports many of Grier's reform measures.
But Gayle Fallon, President of the Houston Federation of Teachers, says parents tired of too much focus on testing and too little support for classroom instructors should vote against the current regime.
"If the teachers are treated fairly, allowed to teach and evaluated in a more even handed and valid method you won't lose them. It's the idiocy factor that we are trying to get rid of in ed reform," said Fallon.
Elsewhere on the local ballot, incumbent Houston Mayor Annise Parker is hoping to clobber prime challenger Ben Hall badly enough to avoid a run-off.
She needs half of the votes cast.
"I think things are looking very good for Mayor Parker," said Mark Jones, Chairman of Political Science at Rice University.
Jones sees far less certainty and far more intrigue in the multiple, tightly contested battles for seats on City Council.
"If you don't turnout you are essentially forfeiting your right to determine who represents you on city council and make significant decisions about your quality of life locally," said Jones.
Early voting turnout in Harris County has been strong, setting a record for odd numbered years.
