K12 Teacher Skills — Development skill for Claude Code

Agent Skills for K-12 Teachers

Source code and evaluation framework for the agent skills that are included with [Claude for Teachers](https://claude.com/solutions/teachers).

Included are two skills:

• k12-lesson-planning: Builds classroom-ready, standards-aligned lesson plans, optionally aligned to a teacher's curriculum
• k12-lesson-differentiation: Adapts an existing lesson into tiered versions (below / at / above proficiency-level) and for specific student needs, keeping core content consistent across tiers

Where noted, materials in this repo were co-developed between Anthropic and Learning Commons, who collaborated to help Claude create classroom materials that are grounded in academic standards and follow best practices from learning science research.

The skills are written to make effective use of the Learning Commons Knowledge Graph [Claude connector](https://claude.com/connectors/learning-commons-knowledge-graph) that is included for all teachers using Claude for Teachers. This connector provides Claude with access to academic standards across all 50 states and progressions beneath them; adapt the skills if your environment does not have access to these tools.

**In Claude for Teachers:** If you have a Claude for Teachers account, there is no extra install needed. These skills are already installed for you.
