| name | standards-crosswalk |
| description | Map a standard from one framework to its closest equivalent in another framework. Use this atom when curriculum-mapping or standards-match needs to align across state frameworks. NEVER fabricate standard codes — return an honest gap if no match exists. Do NOT use this atom to verify that a code is current (use atom-standards-verify) or to author instructional content. |
standards-crosswalk
Maps a standard to its nearest equivalent in a different framework (e.g., FL B.E.S.T. to Common Core, or vice versa). Returns the match with confidence and a rationale. Never fabricates codes.
Input
{
"standard": {"code": "MA.4.FR.1.1", "framework": "FL B.E.S.T.", "text": "Model and express a fraction, including mixed numbers and fractions greater than one, with the denominator 10 as an equivalent fraction with the denominator 100."},
"target_framework": "Common Core"
}
Output
{
"tool": "standards-crosswalk",
"crosswalk": {
"source": {"code": "MA.4.FR.1.1", "framework": "FL B.E.S.T."},
"target": {"code": "4.NF.C.5", "framework": "Common Core", "text": "Express a fraction with denominator 10 as an equivalent fraction with denominator 100..."},
"match_confidence": 0.9,
"rationale": "Both standards address converting tenths to hundredths at grade 4; FL B.E.S.T. also includes mixed numbers explicitly",
"differences": "FL B.E.S.T. explicitly includes mixed numbers and fractions > 1; CCSS addresses this implicitly"
},
"human_review_required": true
}
Do NOT use this atom for
- Fabricating standard codes that do not exist
- Guaranteeing exact equivalence (standards differ across frameworks)
- Replacing curriculum director review of crosswalk decisions
Pipeline note
Follows references/method.md at the Analysis step (standards crosswalk). Output conforms to protocol-layer/metadata-schema.md. human_review_required: true — crosswalk accuracy must be verified by a curriculum specialist.
