The judging is the part of a car show that organizers most often underestimate, and it’s the part that most often determines whether participants come back next year. A show with great cars and bad judging gets remembered as a bad show. A show with average cars and clean, fair judging gets remembered as a well-run event.

This guide covers what organizers actually need to run judging well in 2026 — the score sheet design, the judge logistics, the scoring and tallying, and how to decide between paper and mobile/app-based systems. Chariotz also offers a turnkey judging system if you’d rather not build one yourself; details and contact at the bottom.

What Goes Wrong With Car Show Judging

The same problems show up at almost every paper-based show:

  • Registration sheets get lost between the entry table and the judging coordinator
  • Last-minute walk-ins don’t get added to the right class
  • Cars get assigned to the wrong class because no one verified the entry against the rulebook
  • Judges can’t find their assigned cars on the show field
  • Score sheets get collected late, wet, or smudged
  • Tallying happens in someone’s truck with a calculator while the trophy line forms
  • Trophy presentations run an hour late, half the participants have already left

Most of these aren’t problems with the judges or the cars. They’re problems with the judging system — the workflow, the paperwork, the assignment logic, and the scoring infrastructure. Fixing the system fixes most of them.

Decide on Your Judging Format First

Different formats have different judging requirements. Pick the format before you design the score sheet.

Format What’s Judged Best For
Open class judging Any car against any car in same class General car shows, Cars & Coffee with awards
Concours d’élégance Detail-level originality, condition, presentation High-end classics, originality-focused events
Best in Class + Best in Show Class winners advance to overall Most local and regional shows
People’s Choice / Fan Favorite Vote-based, no formal judging Casual events, supplements to formal judging
Special awards Themed or sponsor-driven (Mayor’s Choice, Best Engine Bay) Adds engagement, low judging overhead

Most local and regional shows use a hybrid: formal Best-in-Class judging by a panel, plus a People’s Choice vote, plus 3–6 special awards from organizers or sponsors.

What an Effective Score Sheet Includes

A good score sheet has 6–10 scoring categories with a clear point range per category. Too few categories and judges default to gut feel; too many and judges run out of patience.

A workable structure:

Category Typical Points Notes
Exterior paint and body 0–10 Look for prep, finish quality, panel alignment
Wheels and tires 0–5 Condition, fitment, period correctness for class
Interior 0–10 Cleanliness, condition, originality or build quality
Engine bay 0–10 Cleanliness, presentation, mechanical correctness
Chassis / undercarriage 0–5 (Skip for casual classes; required for concours)
Stance and overall presentation 0–5 How the car is displayed, signage, owner engagement
Originality or build execution 0–5 Class-dependent; restore-class judges originality, custom-class judges build quality
Difficulty / detail bonus 0–5 Recognizes ambitious builds or rare cars
Total /55 Adjust point distribution to suit your show

Keep the categories on a single side of a printed sheet, with a comments box at the bottom. Judges who run out of column space stop writing useful notes.

Judge Logistics

The right number of judges per class is roughly one judge per 10 cars, with a minimum of two judges per class so that scores get averaged. A single judge per class creates calibration problems — one tough judge or one easy judge skews the entire class.

Workflow rules that prevent the common failures:

  • Brief the judges before the show opens. Walk the score sheet, agree on what “8 out of 10 paint” means versus “5 out of 10 paint.” Calibration matters more than the sheet itself.
  • Print judge assignments by class with car numbers. Don’t ask judges to find their cars on a paper map.
  • Set a hard score-collection time. “All sheets in by 1pm” is what makes the trophy presentation start on time.
  • Have a tally captain who does nothing else. Their job is collecting sheets, double-checking math, and getting results to the announcer.
  • Set tiebreaker rules in advance. Highest single-category score wins; or judge re-vote between tied cars; or oldest car wins. Pick one and document it before the show.

Paper vs. Mobile or App-Based Judging

Both formats can work. The right choice depends on the show size and the organizer’s tolerance for setup vs. day-of chaos.

Paper systems are the right answer for shows with under 30 cars and no significant volunteer staff. The setup cost is zero, judges don’t need devices, and tallying takes 15–30 minutes if the score sheets are well-designed.

The paper failure modes are well-known: lost sheets, illegible writing, math errors in tallying, and the trophy presentation timing problem.

Mobile or app-based judging scales better for shows with 30+ cars or multiple judging classes. Judges score on a phone or tablet, scores upload immediately, and tallying happens automatically as scores arrive. Trophy presentations can start within minutes of the last score being submitted.

The trade-off: setup matters more. Cars need to be entered before judging starts. Judges need device access (their own phones, organizer-provided tablets, or both). Connectivity needs to be reliable on the show field. The first event using any new system always has more friction than subsequent events.

QR-code-based systems are a useful middle ground: each car gets a printed QR code that judges scan to pull up the car’s record, score it, and submit. This eliminates the “judge can’t find car #47” problem and gives organizers real-time scoring visibility.

Tallying and Scoring Rules

A few rules that prevent disputes after the trophy presentation:

  • Drop the highest and lowest score if you have 4+ judges per class. This neutralizes a single overly tough or overly generous judge.
  • Average the remaining scores. Don’t sum — averaging makes scores comparable across classes that have different numbers of judges.
  • Round consistently. Decide whether you’re rounding to whole numbers, half points, or tenths, and stick to it across the show.
  • Document tie-breakers in writing. Hand the rule to the announcer along with the results.
  • Have a re-judge rule. If a class has a tie that the tiebreaker doesn’t resolve, the head judge re-votes between the tied cars.
  • Keep the score sheets. Some shows return them to participants; some keep them for one year for dispute resolution. Either is fine; don’t throw them away the day of the event.

What to Look For in a Judging System

If you’re evaluating a paid judging system or app, these are the questions that matter:

  • Class setup flexibility — can you define your own classes, point structures, and judging criteria? Off-the-shelf systems that lock you into a single rulebook fail when your show has anything unusual.
  • Walk-in registration — can you add cars at the entry table without re-keying everything?
  • Judge assignment by class — can you assign specific judges to specific classes, or do all judges see all cars?
  • Real-time tallying — does the organizer dashboard update as scores come in, or only when judging closes?
  • Offline capability — does the judging app work if the venue’s cell coverage is bad?
  • Excel or spreadsheet import — can you bring in cars from your registration platform without re-typing?
  • Tiebreaker handling — does the system flag ties and prompt for resolution?
  • Export of results — can you export full results for the announcer and for post-show records?
  • Cost structure — is it per-event, per-car, or annual? Per-car often makes sense for one-off events; annual makes sense for clubs running multiple events per year.

A system that handles all of these well is rare. Decide which two or three matter most for your show, and prioritize a system that nails those.

Templates Organizers Can Use

The score sheet structure above is a starting template. Adapt the categories and point distributions to your show’s class structure — a Concours-judged class needs more weight on originality and condition; a stance/show-build class needs more weight on visual presentation and stance; a daily-driver class can run leaner with just exterior, interior, and engine bay categories.

A judges’ calibration sheet — a single page that defines what “8 out of 10 paint” looks like versus “5 out of 10 paint” — does more for judging consistency than any other single document. Most organizers skip this. Don’t.

A tally sheet for the head judge or score captain should have one row per car, columns for each judge, an average column, a class-rank column, and notes. Print it big and laminate it; it gets handled by every judge during the day.

How Chariotz Can Help

If you’d rather not build a judging system from scratch, the Chariotz Car Show Judging System covers the workflow end-to-end: organizer setup of classes and criteria, judge assignment, walk-in registration at the entry table, mobile-app or web-based scoring, QR-code-based car identification, real-time tallying, tiebreaker handling, and exportable results.

The system has been used at events ranging from 30-car local shows to 200+ car concours-style events. We’ve worked through the operational details with organizers across multiple show formats and adjusted the platform based on what actually breaks at real shows.

Pricing is per-car with no per-event setup fee, which works well for organizers running one or two events per year. For clubs running multiple events, we have annual options.

Contact us to talk through your show’s judging needs and get a quote. We can usually have a demo set up within a week and can support your event with onsite or remote help during the judging.
