All our training is based on clear standards set in our three code of practice: for high and ultra-high pressure water jetting, drain and sewer cleaning, and pressure washing. This ensures our training is always rigorous and relevant.

Training shaped by industry-leading standards, built to protect people and improve performance.

Coming Soon
The WJA offers a suite of City & Guilds-accredited standalone courses, supporting the water jetting industry with specialist training and assessment.
These courses help contractors ensure operatives have the skills and knowledge needed to carry out a wider range of specialist services safely, professionally and to a recognised standard.
The WJA’s Level 2 Water Jetting Technician Certificate is the WJA’s first qualification for assessing competent water jetting. It combines our proven City & Guilds courses with a new vocational assessment element to create a qualification, accredited by the ABBE awarding body, that confirms the learner’s competency.
Successful candidates can then apply for the WJA’s Competent Operative Card (renewable every three years with practical assessments) and the CSCS Blue Skilled Worker Card (renewable every five years, with a touch-screen test).
The WJA now allows its courses to be delivered by approved examination providers and trainer/examiners who are based outside the United Kingdom. This is helping meet growing demand for WJA training courses around the world, notably in the Middle East.
The WJA uses the CLiKAPAD digital response system to assess candidates on City & Guilds-accredited water jetting courses.
Candidates answer multiple-choice questions throughout the course, helping trainer/examiners check understanding and revisit topics where needed.
This makes assessment more interactive and helps our trainer/examiners support candidates with different learning styles and abilities.
Candidates must achieve at least 80% to pass. For Practical Modules, CLiKAPAD is combined with a practical assessment, where candidates are observed completing tasks to WJA training standards.
Water jetting operatives and employers can confirm WJA courses are current by viewing details via the WJA portal. They can also scan a QR code on a WJA jetting card or a WJA Digital course certificate. This provides access to a secure verification portal where course details can be viewed.
