All the USHPA National level hang gliding competitions are USHPA
and CIVL sanctioned.

http://ozreport.com/uscompetitiondates.php

All of the following competitions have been sanctioned by the
United States Hang Gliding and Paragliding Association (USHPA). That means that
pilots who fly in them will be awarded National Team Selection System points (NTSS),
http://www.ushpa.aero/competition/ntss1/index.php, which count toward
selecting the US National team that goes to the World Championship.

The Flytec Americus Cup, The Big Spring Nationals, and The Santa Cruz Flats Race
are designated by the USHPA as meets that count toward choosing the US National
Champion (Class 1, Class 2, Class 5, Sport, and Women's). Previously the US
National Champion was chosen at a single competition (the US National
Championships), but this is not longer the case. Now the results from these
three competitions (so far) will determine who is the champion.

The Flytec Americus Cup, The Big Spring Nationals, The East Coast Championship
and The Santa Cruz Flats Race also have CIVL Category 2 sanctioning. They are
listed on the CIVL competition calendar:
http://www.fai.org/civl-events/civl-events-calendar-and-results. The USHPA
is responsible for sending in the applications for CIVL sanctioning, which is
paid for by the meet organizers. Any competition that wishes to be part of the
National Champion selection process needs to be CIVL category 2 sanctioned as
per the rules made by the USHPA Competition Committee at their Fall 2013
meeting.
