WQA offers Instructor-Led Training courses that can get professionals well on the pathway toward professional certification. WQA instructors with real-world experience in POU/POE water treatment lead the discussions, answer questions and encourage sharing of ideas in the live, interactive Zoom sessions.
Class sessions are an hour long, and participants are asked to spend another 30 minutes to an hour on weekly homework assignments. Companies can register several employees to take the course together as a group, which provides support and encouragement for the whole team.
WQA currently offers courses that can help prepare learners for taking the certification exams to become a Certified Installer, Certified Water Treatment Representative or Certified Water Specialist.
New courses are offered throughout the year; check the Events page for registration information or contact us at [email protected].
