Certificate III in Wall and Floor Tiling (CPC31320) is Australia's nationally recognised trade qualification for tilers, delivered by RTOs under the ASQA-regulated VET system, usually as a 3-4 year apprenticeship. It is competency-based: there is no fixed-question exam or percentage pass mark — learners are judged Competent or Not Yet Competent across 20 units through practical work, knowledge questions and workplace evidence. The trade theory spans substrate preparation and wet-area waterproofing to AS 3740, adhesives and grouts, tile materials (ceramic, porcelain, stone, glass), setting out, cutting and drilling, falls to drains, movement and expansion joints, the AS 3958 tiling standard, and construction WHS. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

CPC31320 Wall & Floor Tiling: Suggested Study Strategy
Frequently Asked Questions
How is the Certificate III in Wall and Floor Tiling (CPC31320) assessed?
It is a competency-based VET qualification, not a fixed-question exam. You are judged Competent or Not Yet Competent across 20 units (17 core plus speciality) through practical demonstration, knowledge questions and workplace evidence, with no percentage pass mark.
Who delivers and regulates CPC31320?
CPC31320 is delivered by Registered Training Organisations (RTOs), most often as an apprenticeship with an employer, under the national VET system regulated by the Australian Skills Quality Authority (ASQA). The qualification is listed on training.gov.au.
What Australian Standards does tiling trade theory cover?
Key standards are AS 3740 for waterproofing of domestic wet areas (shower walls waterproofed to 1800 mm, hobs and floors tanked) and AS 3958 for the installation of ceramic and stone tiles (movement joints, falls, lippage and coverage).
What fall is required for a tiled wet-area floor?
AS 3958 recommends a fall between 1:80 (minimum) and 1:50 (maximum) toward the floor waste so water drains without ponding. Too flat causes ponding; too steep is uncomfortable underfoot and hard to tile evenly.
How long does it take to qualify as a tiler in Australia?
Most people complete CPC31320 through a 3-4 year apprenticeship combining on-the-job work with off-the-job training at an RTO. A White Card (construction induction) is needed to work on site, and the trade theory can be revised over a few weeks before assessment.
Is this free CPC31320 tiling practice useful for the trade exam?
Yes — these 100 questions cover the trade theory assessed across the qualification, from AS 3740 waterproofing and AS 3958 to adhesives, falls, cutting and WHS, each with a teaching explanation plus a free daily AI tutor. All content is free forever and updated for 2026.
