The first shot in the battle over school funding has been fired.

Fort Worth Rep. Lon Burnam is sponsoring a bill that would restore all of the $5.4 billion cut from the state’s public schools in 2011. Burnam says Texas’ better economic picture means there’s now funding to undo the cuts, which the Texas Legislature approved during weaker economic times.

More than 600 school districts have sued the state over the cuts. If the courts side with them, it will be up to the Legislature to remake Texas’ funding system. But no ruling is slated to come until after the Legislature adjourns for the year.

In the meantime, Gov. Rick Perry is calling for restraint when it comes to the projected budget surplus. He says public education has been funded at a “rather substantial level” over the last decade.

“As a matter of fact, from 2001 to 2012, public education funding went up 70 percent. Population enrollment went up 23 percent,” Perry said in an interview with Capital Tonight, Thursday.

Rep. Burnam’s assesment is less optimistic. A report prepared by his office says class size increased in nearly 7,000 elementary classes statewide.
