Writing tips for D279

Follow the task instructions and rubric line by line

WGU performance assessments for D279 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.

Show your actual code and test results, not just a description of what you built

WGU evaluators are trained to distinguish genuine software engineering work from a paraphrased summary. Include your actual code, along with evidence it was tested (test cases, output, screenshots). A rubric checking technical competency wants to see the working artifact and proof it functions.

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 D279 assessment as a real deadline.
