Liam Louw
Merit Award, Certifying Plumbing

Liam received the Merit Award of Excellence from the Plumbers, Gasfitters, and Drainlayers Board for his top mark of 97% in his Certifying Plumbing exam in November, 2022. Another certifying exam trainee, Liam Fox, also achieved 97% in this exam, but was pipped for the award because of Liam’s average marks over earlier plumbing exams.

I would like to give a shout-out [to,] and acknowledge Jim Roskvist for the recent support he gave 3 of our boys who were struggling to complete the Drainlayer’s Registration Exam. Jim’s thought process and understanding of how to plan, facilitate and cater for all learning styles was both professional, and relevant with current standard practice. We arranged for Jim to take 6 weeks of night classes to help get our boys through their exam . . . they all passed.

One of our guys had this to say:

“It was awesome, I liked that he was real adaptive to the deficiency report, and his detailed course was on the right track. Super supportive and easy to talk to.”
