The state minimum is 28 and change. Many of the smaller districts in Central Texas still pay just a small amount over that so they can claim they are above state minimums. Some of the larger districts are higher, but have tiny steps for raises about that starting pay.
The district I left starts at 34,000. Kennedale for example, a smaller one high school metro district. starts at 51,000. Granted this had nothing to do with start times, but in a longer view I can see the Central Texas schools having increasing difficulty getting and keeping teachers.
I think the connection to start times is that IF you are not competitive in salary, and trying to recruit statewide, then you have to make other things about the job attractive. Right now I really like that at 2:50 our last bell rings and I have meaningful time left in the day. I don't mind at all being at school at six thirty for tutorial time and we start the day with kids at 7:20. It also lets our high school kids, and I teach where many help support family, have time for after school jobs. My official day is 7:05 to 3:05. I am usually there way early and stay later, but when I need to have an appointment I can usually do it without have to use annual leave and taking a day off. That is a nice extra--and what I mean about providing non salary incentives.
This late start for the older kids means none of that will be available for high school teachers.
