Oneangel - I'm not sure about the Hierarchy of Valley public schools.
I know that South Texas Independent School District is a magnet school district that operates magnet high schools and 7-12 secondary schools taking students from three counties (Cameron, Willacy, Hildalgo), with two schools in Mercedes, one in San Benito, and one in Edinburg. See the profile here:
