1. What are ski medals and levels for?
Booking a ski lesson often means facing the same question: what is my actual level? A child who “knows how to ski” according to their parents might be a snowflake, a first star, or a silver crystal depending on the school. Without a common benchmark, there is a risk of ending up in a group that is too easy — or too technical.
Ski medals and grades were created specifically to meet this need. Each medal corresponds to a set of mastered technical gestures, validated by the instructor at the end of the week. They fulfill four essential functions:
- Motivation through reward — a concrete medal stimulates children and adults to push themselves.
- Harmonizing levels — the same logic across different resorts, seasons, and schools.
- Facilitating future registration — communicating your level becomes simple and precise.
- Structuring learning — each grade opens the door to new slopes and techniques.
In France, three major networks have developed their own systems: ESF, ESI, and Evolution 2. While their names differ, their pedagogical logic is often identical. This guide helps you understand it all and easily convert a level from one school to another using the equivalence table in section 5.
2. The ESF system: from Piou-Piou to the Rocket
Founded in 1945, the French Ski School (ESF) is the largest ski school in the world: 200 structures on virtually every ski area in France, with 17,000 instructors sporting their recognizable red and white uniforms. Its level framework is the most established in French resort culture.
ESF children’s medals (ages 3 to 12)
🐣 Club Piou-Piou (from age 3)
First contact with the mountains. Progress is based on characters — Piou-Piou, Blanchot, Sifflote, Garolou, and Ourson — who mark each stage in a playful way. The goal is confidence, not performance: sliding, falling without getting hurt, and getting back up with a smile.
❄️ Flocon (Snowflake)
The first official medal. The child performs about ten snowplow turns, controls their speed, stops intentionally, and maintains balance over small bumps. It’s the first autonomous green slope experience.
⭐⭐⭐ 1st, 2nd, and 3rd Star
The core of children’s progression, the three stars represent a gradual increase in technical skill:
- 1st star — fluid snowplow turns, first slides/skids, autonomy on green slopes.
- 2nd star — beginning of parallel turns, confirmed snowplow mastery, easy blue slopes.
- 3rd star — obstacle management, rhythm variation, adapted trajectories. Blue slopes without assistance.
🥉🥈🥇 Bronze, Silver, and Gold Star
Reserved for advanced young skiers. Controlled high speed, short turn sequences, mastered skidding, adapting to all snow types. The Gold Star — the maximum grade for the children’s category — validates the ability to ski the entire resort and compete in a timed mini-giant slalom.
ESF teen and adult levels (13+)
For adult and teen skiers, ESF structures progression into four classes. This framework directly corresponds to resort registration forms.
| ESF Level | Key Competencies | Slopes |
|---|---|---|
| Beginner / 1st Ski | First steps, putting on/taking off skis, sliding safely | 🟢 |
| Class 1 | Wide turns, low to medium slopes, simple technical gestures | 🟢🔵 |
| Class 2 | Parallel turns on blue runs, basic skidding mastered | 🔵 |
| Class 3 | Chained skidding, turns of all widths, varied terrain | 🔴 |
| Class 4 | Expert: all slopes, all snow types, introduction to competition courses | ⚫ |
ESF Performance Medals
For skiers seeking timed thrills, ESF offers performance tests in four levels — Bronze, Silver, Vermeil, and Gold — calculated as a percentage of the time achieved by an instructor-opener on the same course.
- La Flèche (The Arrow) — Giant slalom, 25 to 35 gates, 200-250m drop.
- Le Chamois — Special slalom, 30 to 40 gates, 120-200m drop.
- La Fusée (The Rocket) — Super-G, approx. 50 seconds, 8 to 12% slope.
- Le Record — Speed skiing (Kilomètre lancé), 300 to 500m straight line.
- Le Skiercross — Mixed course with whoops, tables, and banked turns.
- Le Saut (The Jump) — Tremplin, performance measured as % of length compared to opener.
ℹ️ The global Performance ski medal is awarded when the skier validates the same level in at least two separate events.
3. The ESI system: Mouse, Crystals, and Runs
With over 45 years of experience, the International Ski School (ESI) federates 65 schools in France and Switzerland. Its strength lies in three pillars: groups limited to 8 students, often multilingual instructors, and a medal offered for free to every child at the end of group lesson weeks — at no extra cost.
The ESI framework is divided into three families: Mice (Souris) for toddlers, Crystals for the main progression, and Runs for snowboard and performance.
ESI Mice (beginner children)
| Mouse Medal | Validated Competencies |
|---|---|
| 🏔️ Snowman (Bonhomme de Neige) | Kindergarten, first steps, first supervised slides. Symbolic reward for the youngest ones. |
| 🐭 Green Mouse (Souris Verte) | Autonomy on the flat, getting up alone, mastered gliding snowplow in kindergarten. |
| 🐭 Bronze Mouse | Direct line with stop, first snaked snowplow turns, autonomous use of lifts. |
| 🐭 White / Blue Mouse | Snowplow turns with return to parallel skis while traversing, mastered intentional stop. |
ESI Crystals: from initiation to expertise
Recognized on an international scale, Crystals are the core of the ESI framework. They mark progression from the first slopes to highly advanced skiers.
| ESI Crystal | Key Competencies | Terrain |
|---|---|---|
| International Crystal | Chained snowplow turns, parallel ski traverse | 🟢 |
| Bronze Crystal | Chained elementary turns, skid at end of curve | 🔵 |
| Silver Crystal | Parallel turns on blue runs, controlled skid while traversing | 🔵 |
| Vermeil Crystal | Short parallel turns on red runs, basic wedeln, braking skid | 🔴 |
| Gold Crystal | Perfected turn with carving effect, advanced wedeln, all snow types | ⚫🔴 |
| Diamond Crystal | Total mastery, off-piste, all snow conditions | ⚫ + Off-piste |
ESI Runs: snowboard and performance
ESI has its own framework for snowboard and timed events with Run medals. Progression goes from beginner to expert, with boardercross, freestyle, and free run tests. ESI also covers Nordic skiing and freestyle with consistent levels across disciplines.
4. Evolution 2: the Yeti family
Founded over 30 years ago, Evolution 2 is a network of ski and mountain adventure schools present in many French resorts — Avoriaz, Val Thorens, Megève, Les Arcs, Chamonix, Super Besse, and others. Its philosophy: technical excellence at the service of pleasure, with groups limited to 8 children maximum and a pedagogy that integrates freeride, natural environment discovery, and authentic sliding sensations.
Where ESF and ESI rely on traditional symbols (stars, crystals), Evolution 2 created its own mythology around the Yeti to motivate children through a unique narrative adventure.
Yeti Evolution 2 levels (children)
| Yeti Level | Key Competencies | Terrain |
|---|---|---|
| 🐾 Yétison | First steps on snow, sliding with help, playful environment discovery | 🟢 |
| 🐾 Petit Yéti | Autonomy on the flat, gliding snowplow, first guided turns | 🟢 |
| 🐾 Yéti 1 | Chained snowplow turns, controlled stop, lift use in autonomy | 🟢🔵 |
| 🐾 Yéti 2 | Elementary turns with parallel return, beginning of skidding, easy blue run | 🔵 |
| 🐾 Yéti 3 | Fluid parallel turns, varied skidding, adaptation to relief and bumps | 🔵🔴 |
| 🐾 Super Yéti | Short and tight turns, all snow types, introduction to off-piste and freeride | 🔴⚫ |
| 🐾 Yéti Rider | Complete alpine ski mastery, freeride, snowboard, or freestyle. Expert level. | ⚫ + Off-piste |
The Evolution 2 philosophy doesn’t stop at the piste: courses include snowshoeing, avalanche awareness for older children, and mountain discovery activities, making it a highly appreciated choice for families seeking a global experience beyond groomed runs.

7. Frequently Asked Questions
Is an ESF medal valid at ESI or Evolution 2?
Yes, in practice. Instructors at all schools know the competing systems and make the correspondence. Mention your medal and the school that delivered it upon registration. In case of doubt, a trial day at the start of the week confirms the right group.
At what age can you start ski lessons?
All three schools welcome children from 3 years old in their beginner spaces. ESF with Club Piou-Piou, ESI with Snowman, and Evolution 2 with Yétison propose very playful approaches with instructors specializing in toddlers.
How much does a ski lesson with a medal cost?
Rates vary by resort and season. For children’s group lessons, expect an average between €150 and €250 for the week (5 mornings). ESI systematically includes the medal at no extra charge. Some ESFs charge for it separately (€3 to €8). For Evolution 2, check directly with the school in your resort.
Do ski medals have an official value?
These are pedagogical rewards, not state certifications. They hold no legal value but constitute a framework widely accepted by all French schools and resorts to evaluate a level and place the skier in the correct group.
My child didn’t get their medal this week — what should I do?
This is perfectly normal: a conscientious instructor only awards a grade if all skills are truly mastered. Stay at the same level for the next stay — the right moves will be better anchored, and the medal will be even more valuable to the child when finally earned.
Summary
Whether it is ESF stars, ESI Crystals, or Evolution 2 Yeti levels, each system aims for the same goal: making progress tangible, motivating, and shareable. The equivalence table in this guide allows you to navigate between schools without losing your bearings — whether you change resorts, networks, or schools from one season to the next.
