As momentum grows behind a push to let Texans carry handguns openly, the biggest fight may be among Second Amendment advocates themselves.

In 2013, when Texas passed its first overhaul of charter school policy since 1995 — the year the publicly funded but privately operated schools were first established in the state — lawmakers included a provision intended to speed the shuttering of poor-performing schools.

But nearly 10 months after the Texas Education Agency marked six operators for closure under the new measure, three of those schools remain open. As those charters prepare to open their doors this month for a new school year, they say they are fighting a process that does not account for the full picture of a charter’s financial or academic health.
