Round Rock and Pflugerville Independent School Districts have both become involved in separate lawsuits against the state claiming the school funding system is broken.

The lawsuits—which make separate and different claims—address state funding cuts officials say directly affect the quality of education for their students.

Round Rock ISD joined Austin ISD and other school districts in a lawsuit against the state—represented by Houston-based Thompson & Horton LLC—that contests the state has not provided adequate funding.

Round Rock ISD officials say the district's target revenue, or per-pupil funding, needs to remain the same or increase.

Meanwhile, Pflugerville ISD joined Hutto ISD, Taylor ISD and other districts in a lawsuit—headed by Austin-based Gray and Becker P.C.—that claims the state has not provided equitable school funding.

PISD has one of the lowest target revenues in the region, and the lawsuit contends school funding should be more evenly distributed.

District officials said larger and continually growing school districts such as RRISD do not want to lose some of their funding to traditionally poorer and smaller districts.

"Every child is due the same quality of education regardless of where their family chooses or can afford to live," PISD Superintendent Charles Dupre said.

Dupre said there are about four school finance lawsuits with different claims that will be combined in one suit and taken to the state in late 2012 or early 2013.
