| name | assessment-item |
| description | Generate exactly ONE assessment item (question + answer key) for a given objective and item type. Use this when a teacher says 'write me a question for this standard' or when assessment-designer needs items one at a time. Do NOT use for generating a full assessment — use assessment-designer. Do NOT use for rubrics — use a separate rubric atom or assessment-designer. |
assessment-item
Generates a single assessment item with answer key. Supports multiple-choice, short-answer, constructed-response, true/false, and matching. Accepts a verified standard and objective; returns item text + answer key + DOK level.
Input
{
"objective": "Students will be able to represent fractions greater than one on a number line.",
"standard_code": "MA.4.FR.1.1",
"grade": "4",
"subject": "Math",
"item_type": "multiple_choice | short_answer | constructed_response | true_false | matching",
"dok_level": 2,
"context": "post-lesson check"
}
item_type: default is multiple_choice. dok_level: 1–4 (default 2). context (optional): helps calibrate complexity (pre-assessment, exit ticket, unit test, etc.).
Output
{
"tool": "assessment-item",
"item": {
"stem": "Which point on the number line below shows the location of 7/4?",
"type": "multiple_choice",
"dok_level": 2,
"options": {"A": "Between 0 and 1", "B": "Between 1 and 2", "C": "Between 2 and 3", "D": "Greater than 3"},
"answer_key": "B",
"rationale": "7/4 = 1¾, which falls between 1 and 2 on the number line.",
"distractor_analysis": "A: Students may confuse 7/4 with 7÷4 without estimating. C/D: Magnitude errors.",
"standard_code": "MA.4.FR.1.1"
Do NOT use this atom for
- Full assessments (use assessment-designer, which calls this atom per item)
- Rubrics or scoring guides
- Items without a standard — always pass a verified standard code
