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.

Fennie is independent and not affiliated with Western Governors University. This is an unofficial study guide.

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

  • • Audience analysis
  • • Document design and structure
  • • Visual aids and data presentation
  • • Instructional and process writing
  • • Persuasive technical documents
  • • Revision and editing

The D339 study guide

How to study for WGU D339, step by step.

  1. 1

    Confirm your assessment format first

    D339 has existed in exam-based and task-based versions. Check your course page on day one — the right plan for an OA and the right plan for writing tasks are different.

  2. 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. 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. 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. 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.

  6. 6

    Let Fennie organize either path

FAQ

Is WGU D339 hard?

No — it's one of the gentler courses in the IT and software programs. The points come from using the course's specific frameworks for audience and document design rather than writing on instinct.

Is D339 the same as C768?

D339 is the current technical communication course that replaced the retired C768. Students still search both codes, but new enrollments take D339.

How long does D339 take?

Most students finish in 1–2 weeks. Confirming your assessment format on day one prevents the only common false start.
