The number of Texas school districts and charter schools considered failing under the state’s accountability system increased slightly in 2016, though the number of individual campuses that received that label decreased somewhat, according to ratings the Texas Education Agency released Monday.

Last year, 55 school districts and charters — or 4.5 percent — fell under the failing, or “improvement required” category; this year, it’s 66, or 5.5 percent. Forty-four of those failing are traditional school districts, while 22 are charter schools.

At the same time, the number of individual campuses labeled as failing fell to 467 in 2016, from 603 last year.
