The timely collection and submission of recertification documents is the responsibility of each certification holder

SKT A / B / C + Platform ID-cards & certificates

must be recertified every 3 years as follows:

  • Application for recertification – please fill out this form: Link

  • Participation in a 4-hour rescue briefing or the Climb Update: Rescue & Ascent Techniques with Bernhard Schütte

    or

  • Participation in a follow-up SKT course within the 3-year validity period

  • Copy of certificate or ID card

  • Valid occupational health examination for “working at heights with risk of falling” (e.g.: according to G41)

  • 16-hour first aid certificate (not older than 4 years; refreshers are ok!)

European Tree Worker (ETW) ID-Card + Certificate

Must also be recertified every three years.

The application for recertification must be submitted on time. “On time” means within the three-year validity period of the certificate. In principle, all required certificates and continuing education hours must be completed within these three years. The so-called “bonus year” is solely for submitting the recertification application – it cannot be used to accumulate additional certificates or continuing education hours. Any certificates or hours obtained during the bonus year will count toward the next recertification cycle.

For successful recertification, we require the following from you:

  • Application for recertification – please fill out this form: Link

  • Copy of certificate or ID card

  • Proof of at least 2 years of tree care activity within the 3-year validity period

  • Proof of physical and mental ability to carry out tree care operations safely, with a medical certificate (For Austria max. validity is: 3 years or otherwise specified by physician).

  • Proof of a valid qualification in first aid, according to the national regulations (For Austria max. validity is: 4 years; refresher courses are eligible).

  • Proof of 30 hours of continuing education* in tree care within the 3-year validity period (not in the bonus year!)

  • Cost: €168.00 excl. VAT (2025)

COMBI recertification: ETW + ETT

Your European Tree WORKER certification (as long as it hasn’t expired yet) and your European Tree TECHNICIAN certification can be renewed together upon request. Dual certification and the use of both titles/logos (ETT + ETW) is possible!
Since both the European Tree Worker and European Tree Technician certifications are valid for three years, it is possible to renew both certificates together upon request. This aligns the expiration dates, making administration and planning easier for both the certified individual and the certification body.
Example 1: ETW expiration date 12/2024, ETT expiration date 12/2025 → new joint expiration date after successful recertification: 12/2028
Example 2: ETT expiration date 12/2025, ETW expiration date 12/2026 → new joint expiration date after successful recertification: 12/2029

  • Application for recertification – please fill out this form: Link

  • Copy of certificate or ID card

  • Proof of at least 2 years of tree care activity (in a consulting and/or management position) within the 3-year validity period

  • Proof of physical and mental ability to carry out tree care operations safely, with a medical certificate (For Austria max. validity is: 3 years or otherwise specified by physician).

  • Proof of a valid qualification in first aid, according to the national regulations (For Austria max. validity is: 4 years; refresher courses are eligible).

  • Proof of a total of 45 hours of continuing education* in tree care within the 3-year validity period (not in the bonus year!)

  • Cost: €239.00 excl. VAT (2025)

ETW + ETT recertifications will only be approved by the EAC if all required documentation is received by the EAC no later than December 31, one year AFTER the certification expires. This means that if your certification expires in 2025, you can submit your recertification application no later than the end of 2026.

You can find out exactly when your certification expires on your certificate or on the EAC website (www.eac-arboriculture.com).
