WGU D339: Technical Communication
D339 teaches workplace technical writing: audience analysis, document design, visuals, and clear instructional and persuasive documents. It replaced the retired C768, and WGU has shifted its assessment format between versions, so check your course page for whether you face an exam, writing tasks, or both.

What makes it hard
The material is approachable; the friction is precision. Whether the version you get is exam- or task-based, points come from applying the course's specific frameworks (audience types, document structures, visual-use rules) rather than writing on instinct. Task submissions bounce for scope and format misses, not bad prose.
What you'll cover

The D339 study guide
How to study for WGU D339, step by step.
- 1
Confirm your assessment format first
D339 has existed in exam-based and task-based versions. Check your course page on day one, because the right plan for an OA and the right plan for writing tasks are different.
- 2
Learn the course's frameworks by name
Audience categories, document types, and design principles are tested and graded as the course defines them. Study the specific terminology, not general writing intuition.
- 3
Practice applying frameworks to scenarios
For each document type, be able to say who the audience is, what structure fits, and which visuals belong. Both assessment formats reward that applied move.
- 4
If you have tasks, draft to the rubric's scope
Task returns in this course are about scope and format: a blog that isn't blog-shaped, instructions missing required elements. Mirror the rubric structure exactly.
- 5
Review with fresh eyes before submitting or booking
Run a revision pass against the course's own editing checklist, then submit the task or schedule the exam once everything maps cleanly.
