StandardGraph

The alignment layer for the global curriculum. Map any standard to its equivalent in another country or exam board — cross-border alignment no single-country tool provides.

175,738 standards across 310 curriculum systems in 50+ countries, cross-walked into a single graph and accessible via Claude.

🎯 Every crosswalk in the graph is now quality-scored. All 208,442 crosswalks carry a 1–5 LLM quality score (100% coverage) — spanning the 88,944 direct country-to-country math edges and every hub-centric mapping across all seven subjects. Weak matches are automatically suppressed and results are ranked by real alignment quality, so what you get back is the strongest match first.

⚡ Try it in 30 seconds — no install. In Claude, go to Settings → Connectors → Add custom connector and paste https://standardgraph.walkmakewalk.com/mcp. No download, no token. (full instructions ↓)

Covers Mathematics, Science, ELA, Social Studies, Computer Science, Arts, and World Languages — US national and state standards plus major international curricula. Ask Claude to look up any standard, trace a concept across grade levels, or find the equivalent in another country's curriculum.

Who this is for:

• EdTech engineers & curriculum teams — mapping content to standards, building alignment features, or auditing coverage across states and countries without hand-building a crosswalk.
• Teachers and curriculum specialists moving between systems — "I taught IB in Singapore, now I'm teaching CCSS in Texas — what's actually different at this grade level?"

If you're doing either of those by hand today, this replaces the spreadsheet.

Install

Option A — Hosted connector (no install) ⚡

The fastest way to try it — no download, no terminal. In Claude, go to Settings → Connectors → Add custom connector, name it StandardGraph, and paste this URL:

https://standardgraph.walkmakewalk.com/mcp

Connect, and StandardGraph's tools are available in any conversation. Works in Claude on web, desktop, and mobile. (Custom connectors require a paid Claude plan. The hosted server runs on modest hardware — ideal for trying it out and light use; for heavy or offline use, install locally below.)

Option B — Local install (offline / self-host)

Runs entirely on your machine against a local copy of the database. Requires Claude Desktop. Open Terminal and run:

curl -fsSL https://raw.githubusercontent.com/swoopeagle/standardgraph/main/install.sh | bash

Then quit and reopen Claude Desktop. Look for the 🔨 icon in a new conversation.

The installer handles everything: downloads the pre-built database (~2.1 GB), installs dependencies, and patches your Claude config automatically.

Optional: better semantic search

Install Ollama and pull the embedding model for richer concept matching:

brew install ollama
ollama pull nomic-embed-text

Without Ollama, StandardGraph falls back to keyword search — still useful, but semantic search finds conceptually related standards even when the exact words don't match. See docs/install.md for full setup details.

Coverage

International coverage is deepest in Mathematics, Science, and ELA. Social Studies, Computer Science, World Languages, and Arts are US/AP-focused today, with international expansion in progress.

Mathematics

Science

ELA (English Language Arts)

Social Studies

US state coverage only; international Social Studies is planned.

Computer Science

World Languages

Using with Claude

StandardGraph works out of the box once installed, but pasting the following into your Claude Project instructions (Settings → Projects → [your project] → Instructions) gives Claude better guidance on how to use the tools and how to interpret results:

You are a K-12 curriculum expert with access to StandardGraph — a database of 175,000+ standards across 310 curriculum systems in 50+ countries, covering Math, Science, ELA, Social Studies, Computer Science, Arts, and World Languages.

## When the user asks about standards, use these tools:
- search_standards — when they describe a concept and want matching standards
- lookup_standard — when they cite a specific standard ID (e.g. CCSS.MATH.6.RP.A.3)
- get_progression — when they ask how a topic develops across grade levels
- get_learning_path — when they want an ordered study plan of prerequisites for a target standard
- map_standard — when they want the equivalent standard in another curriculum or country
- list_systems — when they want to know which systems are available

## Reading crosswalk confidence scores:
- ≥ 0.90: Strong match — same concept, aligned grade level
- 0.85–0.89: Good match — same concept, may differ by ±1 grade
- 0.75–0.84: Plausible — related concept, scope or grade may differ; flag as "worth verifying"
- < 0.75: Weak — treat as a starting point only, not a definitive equivalent

When grade_delta ≠ 0, note which curriculum introduces the concept earlier or later. A negative delta means the source curriculum teaches it at a lower grade than the target.

## Tool chaining patterns:
- Compare two systems on a topic: search_standards in system A, then system B with the same query
- Deep dive on a standard: lookup_standard → follow prerequisites/successors → map_standard to compare
- Cross-curriculum progression: get_progression in CCSS, then map key grade stages to another system
