10. Dutch Approach
The start of STEK 1992
By the start of the STEK system we used a Bottom-up approach
The reason 95% are Small & medium Enterprises (SME) with an
average of 2 till 10 employees.
Most of the time the Boss of the company did the first assessment
The content of the Assessment:
• Theoretical 25 multiple choice questionnaire (0,5 hr)
• Brazing & Assembling (2hr)
• Refrigerant Handling (2hr)
• Installation Inspection (2hr) (since 2010)

Level of Assessment
Basic Appreciation BA
The level of expertise required to
discuss main elements of the Skill
Area with others. Typically: Theoretical assessment
- Recognises the importance of
the Skill Area to business and
society, and its relevance to own job. Practical assessment
- Interprets information on the
Skill Area for own tasks
- Knows where to obtain
professional help in the Skill Area.
Working Knowledge WK
The level of expertise required for
direct involvement in the decisions and
actions of the Skill Area. Typically: Theoretical assessment
- Assesses and diagnoses issues in the
Skill Area; Practical assessment
- Provides reasoned challenges to
specialists in the Skill Area;
- Supervises or directly works with
practitioners of the Skill Area.

Level of Assessment
Fully Operational FO
The level of expertise required to
perform personally the majority of the
activities of the Skill Area. Typically: Theoretical assessment
- Performs all normal activities in the Practical asessment
- Resolves problems and makes
improvement in the Skill Area;
- Applies and adapts best practice in
the Skill Area to local
conditions;
Leading Edge LE
The level of expertise required for
significant development of the Skill Theoretical assessment
This Skill Level applies to a small
minority of positions and individuals. Practical assessment
- Creates major innovations in the Skill
- Creates best practice in the Skill
- Acts as a recognised reference point
for the Skill Area.

Facts & Figures
• STEK: public private partnership (foundation) with
18 years of experience
• Certification of personnel: 24.000 diploma’s
• Certification of installers: 2000 stationary
• Auditing through independant bodies every 18/24
months (audit of installer and installations by end-
user)
• Assessment by STEK assessors
• No Training/Education: is for the free market
Thematic Meeting Hungary 19-10-11 20

21. Dutch Approach
Facts & Figures
 High awareness about the environmental impact of RAC & heat pump
equipment by the industry sector, including certified installers, their personnel
and operators
 Equipment quality improved. Equipment manufacturers and installers
increased the quality of both equipment (longer life cycle) and services
 Operators/and-users benefit from a higher reliability of their systems and thus
higher productivity of their own activities
 Lower operational costs for operators due to professional leak checks resulting
in direct refrigerant and spare part savings. Leak-tight equipment, ensuring
optimal refrigerant charge, also results in higher energy performance.
 Higher quality education and training through assessment structure
 Real leakage rate figures based on the refrigerant registration by certified
installers. Emission figures 3-5 % depending on refrigerant/application

Facts & Figures
• 8000 Active STEK-technician/year
• STEK fee for installers = € 500 per STEK-Technician/year
• Average yearly STEK installers fee: by 3 STEK
technicians € 750
• Overhead costs: € 125 per STEK technician
• Productivity: 1500 hours per STEK Technician/year
Result
STEK system costs per STEK
Technician/hour:
€ 0,33 (€ 500/1500hr)
