Stone painting (also called rock painting) keeps getting judged on the same sheet as glass painting or poster making, which misses what’s actually different about it: candidates are painting onto an irregular, opaque, naturally-shaped 3D surface, not a flat translucent one or a flat paper sheet — so the design has to work WITH the stone’s own shape and curve rather than ignore it, and the paint has to cover a rough, absorbent surface cleanly. Schools, church youth wings and club fests running stone/rock painting alongside glass painting or mosaic art need a rubric built for this surface specifically. Here’s a practical judging criteria you can hand to a panel today, plus how to run the item so scores hold up when candidates compare notes afterward.
What counts as a competitive stone/rock painting item
A judged stone painting item gives each candidate one or more smooth river stones or rocks, a set of acrylic/poster colours and brushes, and a time window, then scores the finished piece on how well the painted design uses the stone’s natural shape and how cleanly it’s executed. Common formats:
- Single-stone motif painting — one medium-to-large stone painted as a single subject (an animal face, a mandala, a flower), the most common school-level format
- Multi-stone set painting — several small stones painted to form a connected set (a family of animals, a line of ladybirds, matching pairs), judged additionally on how well the set works together
- Theme/festival stone painting — stones painted around an announced theme (a festival motif, a message, a local symbol), common at club and church-fest level
- Freehand/abstract stone painting — open design, no announced theme, usually reserved for the senior/open band
Typical age groups follow the same bands as other craft items — LP/UP/HS/HSS at school level, Junior/Intermediate/Senior at a church-style talent test, or numbered Group 1-5 at a club fest — with younger groups usually given a larger, smoother, pre-cleaned stone and a simple pre-set theme, while older groups work with smaller or more irregular stones and an open or freehand design. This is an individual item unless the event explicitly runs a multi-stone group/set variant.
The 100-mark judging rubric
| Criterion | Marks | What the judge is actually checking |
|---|---|---|
| Use of the stone’s shape | 25 | The design is built around the stone’s natural curves, bumps and contours rather than painted as if the surface were flat — a motif that genuinely follows the shape scores highest |
| Paint coverage & finish | 20 | Even, opaque coverage with no bare patches, smudging, drip marks or visible brush-stroke unevenness on the rough surface |
| Colour use & blending | 20 | Deliberate colour choices and clean blending/shading rather than flat single-colour fills with no depth |
| Composition & detailing | 15 | Proportion, fine detail (eyes, patterns, line work) and overall balance of the design on the available surface |
| Theme relevance | 10 | The finished design clearly reflects the announced theme, where the event sets one |
| Originality | 10 | A fresh subject or treatment rather than a direct copy of a well-known reference rock-painting design |
Print this as one line per candidate on the judge’s sheet (chest number, each criterion’s marks, total) so a panel of 2-3 judges can score every entry in one pass once all stones are laid out side by side — judging each stone as it’s handed in, rather than comparing the full set together, makes the shape-use and finish marks far less consistent across judges.
Deductions and disqualification
| Issue | Deduction |
|---|---|
| Bringing a pre-painted or partly-finished stone into the venue (where the event requires work done on the spot) | disqualification on confirmation |
| Outside help (another person painting) during the time window | disqualification on confirmation |
| Using a stencil, transfer or pre-printed design sheet instead of freehand painting | disqualification on confirmation |
| Exceeding the time window | -5 per 10 minutes over, organiser’s call on a hard cutoff |
| Paint still wet/smudging or visibly unfinished patches at a handling check at time-up | -5 to -15 depending on how much of the stone is affected |
| Stone breaks or paint flakes off on normal handling due to poor surface prep | -5 to -10, organiser’s call |
Age-group, format and time-limit table
| Band | Format | Time limit | Material note |
|---|---|---|---|
| Junior / LP | Large, smooth, pre-cleaned stone, simple pre-set theme (an animal, a flower) | 30-40 min | Stone and basic colours supplied, broad brushes only |
| UP / Intermediate | Medium stone, theme announced at start, some freehand detailing expected | 40-60 min | Candidate chooses own colour palette from a supplied set |
| HS / Senior | Smaller or more irregular stone, freehand composition, fine detailing expected | 60-75 min | Full colour freedom, candidate may bring own fine brushes |
| HSS / Super Senior | Multi-stone set or open/abstract theme, full technique freedom | 75-90 min | Full material and tool freedom, organiser’s call on stone size/count |
How to run the judging, step by step
- Announce the theme (if any), stone size/count and time window at the start, not partway through — a mid-event rule change invites appeals.
- Supply pre-cleaned, dry stones centrally where the event provides them, so no candidate starts with a surface easier to paint on than another’s.
- Collect finished work promptly at time-up and lay every entry out together (table or wall display) before judging begins — a brief check that the paint has genuinely dried/set, not still wet or smudging, is a standard step unique to this item.
- Score by chest number only; cover names and units so the panel judges the piece, not the candidate.
- Score independently per judge, then average or total per the event’s own method — don’t let judges confer mid-scoring.
- Record marks straight into eTalenter against each candidate’s chest number so the item closes into the same live tabulation as every other item on the programme.
Stone/rock painting vs. glass painting vs. mosaic art — picking the right sheet
These sit on the same craft shelf but reward different skills, so don’t reuse one rubric across all of them:
- Stone/rock painting scores a design painted onto an irregular, opaque, naturally-shaped 3D surface, where using the stone’s own curves and getting clean, opaque coverage on a rough surface are the named criteria — a mechanic no flat-surface item needs.
- Glass painting scores outline-and-fill technique with paint on a flat, translucent surface, judged partly by holding the piece to light — no 3D shape to work around at all. See glass painting competition judging criteria.
- Mosaic art scores edge-to-edge placement of small, discrete assembled pieces — tile, seeds, pebbles — with gap consistency and adhesion as the named criteria, with no painting involved at all. See mosaic art competition judging criteria.
If your programme runs more than one of these, print a separate sheet for each and lay out all entries for side-by-side judging the moment the time window closes — judging stone painting against a generic “painting” rubric is the most common cause of panels missing uneven coverage or ignoring how well the design actually uses the stone’s shape, which is the single defect that matters most in this item.
FAQ
What materials are typically allowed for stone/rock painting?
Varies by age band and what the event supplies: large pre-cleaned smooth stones with broad brushes and basic colours for juniors, medium stones with a wider palette for intermediate groups, smaller or more irregular stones with fine brushes for seniors working freehand. State the allowed material list on the judge’s sheet and in the pre-event brief so there’s no ambiguity about whether a candidate can bring their own stone or must use what’s provided.
How is “use of the stone’s shape” actually judged?
Judges look at whether the design genuinely follows the stone’s bumps, curves and natural contours (a motif that uses a raised ridge as a nose or spine, for instance) rather than being painted flat across the surface as if it were paper. This is the single most distinctive criterion for this item and is worth explaining to candidates in the pre-event brief, since it’s unfamiliar compared to flat-surface craft items.
Should a multi-stone set be judged differently from a single stone?
The same six criteria apply, but note on the judge’s sheet whether an entry is a single stone or a set, since a set is additionally judged on how well the pieces work together (consistent style, scale and finish across the set) under composition & detailing. Don’t mix single-stone and set entries in the same judging round if your event offers both — score them separately where numbers allow.
How many judges should score a stone/rock painting item?
2-3 independent judges is standard for any visual-craft item, same as glass painting or mosaic art, with marks averaged or totalled per the event’s own method. A single judge’s eye for surface coverage or shape-use varies enough that a panel materially improves consistency.
