Use the rubric provided to ensure you are competent in all requirements.
SUBMIT D482 PERFORMANCE ASSESSMENT
MULTIPLE ATTEMPT POLICY
WGU evaluators assess Performance Assessments using the rubric provided with the task. Submissions are evaluated in the order
they are received by WGU's evaluation faculty. The standard evaluation timeframe is 72 hours after submission. Once a task is
evaluated, an evaluation report will be provided. Students should use the evaluator's feedback in the report to revise any rubric
items marked as Not Competent or Approaching Competency. If students have questions about the revisions, they should work with
their Course Instructor to clarify the requirements.

Syllabus: D482 Secure Network Design
If a task is submitted and more than 50% of the rubric items are marked as Not Competent or Approaching Competency, the
resubmission of the task will be locked. In this case, the student must work with their Course Instructor to understand the revision
requirements and have the task unlocked.
If a task is submitted more than three times and any of the rubric items are marked as Not Competent or Approaching Competency,
the resubmission of the task will be locked. In this case, the student must work with their Course Instructor to understand the
revision requirements and have the task unlocked.
