Rubric-Aligned Research and Planning Packet | 2026/2027
Academic-use note. This packet is designed to support independent drafting against
the D401 rubric. It provides a complete analytical plan, data interpretation, source
support, and quality-control checklist, but it is intentionally not a ready-to-submit
graded assessment. Write the final submission in your own words and verify it against
the rubric visible in your WGU course portal.
Prepared from the current D401 course description, the task structure reflected in the supplied materials, and current
public-health guidance.

1. Assessment Map
D401 is a 3-CU course in WGU's public-health curriculum. The current institutional catalog
emphasizes analyzing disease determinants, collecting evidence, interpreting patterns, and using
those findings for decision-making. Those competencies align directly with the XJM1 conjunctivitis
task structure.
What a strong response
Criterion Focus
needs
A Risk-factor identification Name two scenario-specific
factors that plausibly increased
transmission.
B Transmission analysis Explain a credible person-to-
person or fomite pathway for
each risk factor.
C Mitigation Give two concrete
interventions tied directly to
the identified factors.
D Additional evidence Identify two missing data
sources that would materially
improve the investigation.
E Value of evidence Explain how each missing
source would reduce
uncertainty or improve control
decisions.
F Outbreak patterns Identify two measurable
differences between School A
and School B.
G Pattern explanation Give a plausible epidemiologic
explanation for each pattern
without presenting speculation
as fact.
H Isolation decision Evaluate whether 7-10 days of
home isolation for diagnosed
initial cases was sufficient.
