How people learn: the bodies that qualify instructors.

What this page is and is not

This page contains no technique. It describes the professional bodies that train and certify ski and snowboard instructors, using each body's own published standards. Those bodies are not ski schools selling lessons, and this site does not recommend any school, resort or instructor.

The international level: ISIA

The International Ski Instructors Association (ISIA) calls itself the worldwide association for professional snow sport instructors; its President's office is in Silvaplana, Switzerland. New members are admitted only by its Assembly of Delegates, which also adopts its quality standards.

The ISIA Quality Standards in force are the version adopted by the Assembly of Delegates at Vail on 7 April 2025. The standard first took effect after approval at Jesolo on 22 May 2008. It sets two levels of international recognition:

The training components ISIA names for the Stamp include safety on and off piste, methodology and didactics, first aid, tourism and basic rights, environment and nature, and history and culture; they are named here only, without their content. To stay active, ISIA-recognised instructors must complete national further training of one day a year (or two days every two years, or three every three); otherwise they lose their Stamp or Card entitlement until they complete it.

How many national associations belong is not settled. The Canadian Ski Instructors' Alliance (CSIA) says the ISIA includes the national ski teaching associations of 38 alpine nations, while the ISIA's own basics page shows about 45 member flags without a total. Neither figure is dated. The CSIA also notes that the Interski Congress, the international meeting of ski teaching systems, is held every four years.

United States: PSIA-AASI

PSIA's "Alpine Certification Standards, Level 1, Level 2, Level 3" are dated "Updated: September 2026". They tie the three certification levels to the three skier zones of the American Teaching System:

• Level 1: for teaching beginner and novice guests.
• Level 2: beginner to intermediate.
• Level 3: beginner to advanced.

Each level is assessed on four areas: professionalism and self-management, people skills, teaching skills and technical skills. PSIA-AASI also publishes separate certification standards for snowboard (under AASI), cross-country, telemark and adaptive, which were listed in search results but not read. A search summary of PSIA-AASI's ISIA page says its ISIA Stamp needs Level III certification and current continuing education; that is unconfirmed.

PSIA dates from 1961 by three accounts: the ISHA compiled timeline, ISHA's obituary of Bill Lash, which calls him one of PSIA's original founders that year, and PSIA-AASI's own About page ("since 1961"). Search summaries say PSIA formed AASI, the body under which the snowboard standards are published, in 1997; the page they come from could not be opened, so that date is unconfirmed.

Canada: CSIA and CASI

The CSIA says it was founded in 1938, is a not-for-profit, federally recognised teaching institution with four certification levels, has six regions (British Columbia/Yukon, Alberta, Central, Ontario, Quebec and Atlantic), and is a member of the ISIA. The ISHA timeline also lists 1938, in the Laurentians. A CSIA page seen only in a search summary describes it as Canada's sole ISIA member, authorised to issue the ISIA Stamp alongside CSIA certification; that is unconfirmed.

Snowboard instructors in Canada have a separate body. The Canadian Association of Snowboard Instructors (CASI-ACMS) says it was founded in 1994, is a not-for-profit with more than 7,500 active members, and certifies instructors from Level 1 to Level 4 plus Park 1 and 2, Carving and Big Mountain. It describes itself as one of the only snowboard-only certification bodies not connected to a ski instructor association. CASI's page gives its head office as Collingwood, Ontario; a search summary of Wikipedia gives Cambridge, Ontario. This site follows CASI's own page.

United Kingdom: BASI

BASI, the British Association of Snowsport Instructors, says it has worked since 1963, is a not-for-profit UK membership organisation and calls itself "the UK's official awarding body" for professional ski and snowboard instructors. It qualifies instructors in five disciplines (ski, snowboard, telemark, adaptive and cross-country) on a modular pathway from Level 1 to Level 4, and says its qualifications are recognised by the ISIA. BASI says most of its courses are rated on the Scottish Credit and Qualifications Framework (SCQF), that each Level 1 qualification carries 7 UCAS points, and that it is a CIMSPA NGB Training Partner.

Two details are unsettled. BASI's about page gives an Edinburgh address, while a search summary describes BASI as based in Grantown-on-Spey; this may reflect an office move, but that is unconfirmed. BASI's course listings, seen only as a search summary, name Level 4 the International Snowsport Teaching Diploma (ISTD).

Children: FIS's campaign

FIS's undated Factsheet General says its Bring Children to the Snow campaign supports 1,056 organisers in 53 countries, with over 1,000 events a year. That is FIS's own claim and carries no date.

What was not covered

Instructor systems in France, Switzerland, Austria, New Zealand and Australia, and Snowsport England's role, were not researched for this site. Adaptive instruction is on adaptive and Para skiing, and the behaviour expected on the slope is on the codes of conduct.
