+- **Use when:** Preparing assessment for diverse audience
+- **Skip when:** Items have already been reviewed for bias
+
+### adaptive-logic-designer

+
+## Assessment Decisions
+
+### Item Type Selection
+- **Multiple choice:** Efficient, reliable, good for knowledge/comprehension
+- **Short answer:** Tests recall and brief explanation
+- **Essay:** Tests higher-order thinking, writing skills
+- **Performance task:** Tests application in authentic context

+
+### Number of Items
+- **Rule of thumb:** 3-5 items per objective for reliable measurement
+- **Short quiz:** 5-10 items (formative)
+- **Unit test:** 20-30 items (summative)
+- **Comprehensive exam:** 50-100 items
+
+### Difficulty Distribution
+- **Easy (p > 0.7):** 20-30% of items
+- **Medium (0.4 < p < 0.7):** 40-50% of items
+- **Hard (p < 0.4):** 20-30% of items

+## Trade-offs to Consider
+
+| Decision | Benefit | Cost |
+|----------|---------|------|
+| More items | More reliable measurement | Longer test time, fatigue |
+| More MC items | Easier to score, reliable | Limited higher-order measurement |
+| More open-ended | Richer data, higher-order | Harder to score, subjective |
+| Adaptive testing | Precise measurement, efficient | Complex to develop, requires item bank |
