TO CLARIFY:
 
 
Rule 5-1-1:
 

All contest officials shall be secured by the host school.  Line judges,
 "unless determined otherwise by state association policy", shall be provided by the host school.

Although the rule book calls for host management to provide lines callers per NFHS, our Texas state association (UIL) has opted to allow the visiting team to provide one lines caller for each match.  The only time the home team provides two is when the visitor comes without anyone to call lines.  This rule change was originally made to assure that no match would be played without lines callers.
