D339 Technical Communication, catalog number COMM 1115, is the three-CU general education course covering the editing of professional communications, etiquette in digital environments, and the construction of persuasive, informational and research-based artifacts along with multimedia presentations. It is the least essay-like writing course in the catalog. What you produce here are documents with a job: a set of instructions someone follows, a report someone decides from, a deck someone sits through.
Technical writing is scored on usability
Academic writing is judged on whether an argument holds. Technical writing is judged on whether a reader can do the thing. That difference changes almost every decision, and the students who struggle in COMM 1115 are usually the ones who write well in the academic register and keep writing that way.
Concretely, it means the reader is not reading. They are scanning, stopping, acting, and coming back. Long paragraphs are a defect rather than a sign of effort. Headings are load-bearing structure rather than decoration. Numbered steps beat prose descriptions of a process every time, because a person holding a wrench cannot parse a subordinate clause. Where an academic paper delays its conclusion for effect, a technical document leads with it, because the reader may stop after the first screen.
The course also names three artifact types explicitly, and they behave differently. A persuasive artifact has to move someone who has a competing priority, so it needs a cost or a risk near the top. An informational artifact has to be complete and neutral, so it needs coverage and consistent terms. A research-based artifact has to be traceable, so it needs citation discipline that the other two can go lighter on. Reading which of the three you are producing, before choosing a structure, is half the work.
Digital environment etiquette is a scored competency
The catalog description names etiquette in digital environments, which students routinely read as filler and evaluators do not. It covers channel choice, tone in asynchronous writing, and the professional consequences of how a message is composed and distributed.
The practical content is more specific than manners. Channel choice means knowing that a decision requiring a record belongs in writing while a disagreement requiring nuance usually does not. Tone means recognising that a message with no greeting and three imperative sentences reads as anger to a reader who cannot see your face, regardless of what you felt when you sent it. Distribution means understanding that copying a supervisor changes the meaning of a message, and that a reply to all can be an act of escalation.
Where a rubric aspect touches this material, generic statements about being polite will not satisfy it. Name the channel, name the reason for choosing it, and name what would have gone wrong on the alternative.
Turning scored aspects into a build plan
WGU keeps scoring detail inside your Course of Study rather than in the public catalog, so open the rubric before you design anything. Count the aspects. Each is scored on its own three-point scale and a score of 2 in every aspect passes a task. Nothing averages, so a beautifully designed document with a weak audience analysis still comes back.
In technical communication the aspects usually split between the artifact itself and the reasoning behind it. Documents get scored for structure, clarity, accuracy and design. The reasoning gets scored separately, often as a rationale or a memo explaining choices. Treat both as deliverables with their own word budgets. Students routinely spend all their time on the artifact and thirty minutes on the rationale, which reliably returns the rationale aspects.
A worked word budget. Take a task with an artifact plus a 900-word rationale covering four scored aspects. Allow 80 words to open and 80 to close, leaving 740 across four aspects, or 185 each. That is short, so precision matters more than usual: one sentence naming the decision, two giving the reason, one naming the alternative you rejected and why. Four aspects times four sentences is a complete, tight rationale. Where a fifth aspect asks about accessibility or audience, take 40 words from each of the others rather than letting the document run long, because technical rubrics frequently score conciseness itself.
Structures that fit the three artifact types
Follow the format your directions name. Where the choice is yours, match the structure to the artifact type rather than reusing one shape for everything.
| Artifact | Structure that works | Design element that carries weight |
|---|---|---|
| Instructions or procedure | Purpose, prerequisites, numbered steps, verification, troubleshooting | One action per step, verb first, no step containing the word and twice |
| Informational report | Summary, background, findings by heading, conclusion, references | A summary that could be read alone and still be useful |
| Persuasive brief | Recommendation, cost of inaction, evidence, objections answered, next step | The ask stated in the first two sentences |
| Research-based document | Question, method of gathering, findings, limitations, sources | Traceability from each claim to a named source |
| Multimedia presentation | One idea per slide, speaker notes carrying the detail | Slides that fail as a document on purpose, because the talk is the document |
| Rationale or memo | Decision, reason, rejected alternative, per scored aspect | Explicit link between an audience trait and a design choice |
The multimedia row causes the most argument. Students build slides dense enough to read on their own, then get scored down for text-heavy design, then rebuild them empty and get scored down for missing content. The resolution is speaker notes. Detail lives there, the slide carries one idea, and both aspects are satisfied.
Editing craft that survives a technical rubric
Editing is named in the course description, which means it is not just something you do before submitting. It is content. These passes catch most of what technical rubrics penalise.
- Term consistency. Pick one word for each object and never vary it. Calling it a form on page one and a request on page three is a defect even though a thesaurus approves.
- Step atomicity. Any numbered step containing two actions becomes two steps. This single pass fixes most instruction-set returns.
- Scan test. Read only headings and the first line under each. If that does not convey the document, the structure is wrong.
- Accessibility basics. Meaningful heading levels in order, descriptive link text rather than click here, sufficient colour contrast, and tables used for data rather than for layout.
- Number and unit check. Every figure carries a unit and a basis. A report saying throughput improved by 40 percent without saying from what is unusable.
- Citation pass for research-based artifacts only. Where the document is informational or persuasive, cite anything borrowed, and where it is research-based, cite in the style the directions name and match every entry.
What separates Competent from a return
WGU records outcomes as Competent or Not Competent, with no letter grades and no ordinary grade point average. Performance assessment work can be revised and resubmitted without penalty, so the cost of a return is queue time and rework inside a six-month flat-rate term rather than a mark you carry.
Technical communication work that passes on the first read shares these features:
- The document type matches the task's purpose, and the structure matches the type.
- A reader who is not you could complete the task or make the decision using only the document.
- The rationale names specific audience traits and links each to a specific design choice.
- Terminology is consistent, steps are atomic, and headings would work as a table of contents.
- Where sources are used, they are attributed in the style the directions name.
If the version on your plan includes a proctored objective assessment, the boundary is fixed. Proctored assessments are yours to sit. We prepare with drills, practice documents and an honest readiness read. We do not sit or assist during an assessment, and we never ask for portal credentials.
Six mistakes that cost time in D339
- Writing an essay and formatting it as a report. Headings applied to essay paragraphs do not make a technical document. The paragraphs themselves have to change shape.
- Skipping the audience analysis. Every design decision in a technical rubric is judged against a reader. Without a named reader there is no way to justify anything.
- Writing instructions from memory. Perform the procedure while writing it. The step you forgot is always the one the evaluator tries.
- Treating design as decoration. Spacing, heading hierarchy and consistent alignment are scored as usability. Colour schemes are not what is being assessed.
- Putting the recommendation last in a persuasive artifact. Academic habit says build to the conclusion. Professional readers stop before you get there.
- Leaving the rationale for the final hour. It is short, it is heavily scored, and it is the piece that proves your choices were choices.
How support works on this course
Send the rubric from your Course of Study and the task directions. What comes back is aspect-mapped: a model artifact built to the right type, a rationale that links audience traits to design decisions, speaker notes where a presentation is involved, and a walkthrough that explains each choice so the next document you build is your own work done faster.
Because a WGU term runs six months at a flat rate, the metric that lowers your cost per course is how many you close inside the term. Technical communication rewards a fast, disciplined pass more than almost any other general education course, because the deliverables are short and the rules are checkable.

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
