The Capstone in Psychology is the degree's culminating project — applying real psychological expertise to a genuine issue of personal interest, with an eye toward building a professional portfolio.
What D578 covers

Writing tips for D578
Follow the task instructions and rubric line by line
WGU performance assessments for D578 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 psychological theory in a concrete case or example, not just definitions
WGU evaluators are trained to distinguish genuine psychological analysis from a paraphrased textbook summary. Apply the specific theory or concept to a concrete case, scenario, or example the task provides, and show the reasoning connecting the theory to that specific situation.
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 each D578 assessment as a real deadline.

Why students seek help with D578
Because this is a capstone drawing on the whole degree, a narrow response addressing only one psychological sub-area (e.g., only cognitive psychology) rather than genuinely synthesizing across the program's breadth is the most common shortfall.
