Hospitality
Requires friendly and energetic individuals.  Some responsibilities include: transportation of officials, morning coffee and donuts, and exhibitors party.  Also, the Hospitality Committee helps plan the Year-End Awards Banquet.

Paddock Steward
The Paddock Steward keeps track of horses arriving to the warm-up ring and maintains safety.  Many riders will ask the Paddock Steward the official time, if the show is on time, and which horses go before  them.  It helps to have a loud voice!

Ribbons & Test Pick-Up
Many volunteers enjoy this job, as you get to talk to everyone! Volunteers help riders when they come up to pick up tests and any ribbons he or she won.  Good organization skills are a must, since it's very easy to get tests and ribbons mixed up!

Ring Steward and Bit Check
The Ring Steward and Bit Checker are often the same person.  The Ring Steward is responsible for the proper horse going to the correct ring.  The Ring Steward also closes any gates to the ring if necessary.  After each horse completes the test the bit, whip, and spurs are checked.  Knowledge of legal equipment is necessary.  The USA Equestrian Rule Book details legal equipment.

Runners
Runners are often energetic individuals that are responsible for getting scored test sheets from the judges to the scorers, then to the test pick-up area.  Judges will often ask runners to bring a bottle of water etc.

Scorers
Sometimes this is included in the Tabulator Job.   A scorer calculates the percentages of each test.  Math Skills are very handy for this job.  At some shows, Scorers also post scores on the scoreboard.

Set-Up and Clean-Up
The Set-Up group of volunteers are the first to arrive at the show grounds (usually the day before the show starts).  They set up the competitions rings, stabling charts, signs, and generally get the grounds ready for the first competitor to arrive.  The Clean-Up group takes down arenas, throws trash out, and packs up horse show items in order to leave the facility better than it was found.
