The Drywall Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests drywall (gypsum board) installation and finishing knowledge — materials and board types, framing, layout and fastening, hanging board on walls and ceilings, taping and finishing to the levels of finish, and tools, estimating, safety and defects — written to Gypsum Association technical resources and OSHA construction safety guidance for 2026.

Every question is based on published standards and research — including Gypsum Association technical resources (Gypsum Association), 29 CFR 1926.502 Fall protection systems criteria and practices (OSHA) — and each answer is explained with its source.

The Gypsum Association defines six levels of finish, from Level 0 (no finishing) to Level 5 (the highest, a skim coat over the whole surface). The required level depends on the final decoration and lighting.

Hanging board can be horizontal or vertical. Horizontal hanging on walls reduces the length of butt joints and is common in residential work; the right choice depends on wall height, framing and local practice.
