Expert Strategies, Review of 50 Key Quizzes,
and Practice Questions for Guaranteed Success
(2026/2027)
This WGU D184 Standards-Based Assessment (OA) is a 50-question, multiple-
choice objective assessment focused on designing, implementing, and analyzing
standards-based grading, proficiency scales, and assessment blueprints. It
measures competency in aligning assessments with learning targets (e.g., Marzano
frameworks) to track student mastery.
Key Topics Covered in D184 (50 Questions)
• Proficiency Scales: Designing 4-point scales, interpreting "mounting
evidence" for summative scores, and understanding declarative vs.
procedural knowledge.
• Assessment Blueprints: Mapping assessments to specific standards,
ensuring alignment, and creating valid measurement topics.
• Standards-Based Grading: Tracking progress over time rather than
averaging grades, focusing on mastery of learning targets.
• Data Analysis: Analyzing student performance data to determine
proficiency levels and adjusting instruction.
• Validity & Reliability: Ensuring assessments actually measure intended
standards without bias.
Exam Preparation Tips
• Focus on Concepts: Do not rely solely on memorizing question banks;
understand why an answer is correct, especially regarding how to
determine a final 3.0 or 4.0 score from a set of data (e.g., in, "Properties of
Energy" had the most consistent evidence of 3.0).
