Writing tips for D655
Follow the task instructions and rubric line by line
WGU performance assessments for D655 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.
Ground your work in a specific audience or organization, not generic advice
Courses like D655 typically hand you a specific audience, brand, or organizational scenario and expect your work to genuinely fit that context, not communication/design principles in the abstract. Evaluators check whether your reasoning is grounded in the specific scenario given.
Because WGU is self-paced, don't let "no deadline pressure" become no submission
There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for the D655 assessment as a real deadline.

Why students seek help with D655
Candidates sometimes build a visually polished prototype without genuine accessibility considerations (contrast, screen-reader compatibility) — the rubric typically wants those accessibility features explicitly addressed.
