The school finance trial is gearing up again after a holiday hiatus.
More than 600 school districts responsible for educating three-quarters of Texas' over 5 million public-school students have sued the state.
They claim that $5.4 billion in cuts to public education and grant programs approved in 2011 by the state Legislature have made funding inadequate and inequitable.
The districts spent nearly two months calling witnesses and presenting evidence of the effects of the cuts to state District Judge John Dietz.
Texas' attorney general's office argues that funding is adequate. It is now calling witnesses and will do so for about two more weeks once the case resumes Monday.
Testimony may continue through the end of the month. Dietz says he plans to rule quickly once the case is over.
