What it does
Anthropic's repository holds the source of the skills behind Claude for Teachers, plus the rubrics used to score them. The k12-education plugin bundles four skills for math, English, science and social studies: k12-lesson-plan-creation builds a standards-aligned lesson plan with student materials and an observation template, k12-lesson-differentiation splits an existing lesson into below, at and above proficiency versions and versions for specific student needs, k12-lesson-prep works through the lesson's key student task with the teacher and leaves a 200 to 300 word note, and k12-check-for-understanding writes one to three formative math items whose wrong answers come from documented misconceptions. The skills are written for the Learning Commons Knowledge Graph connector, which gives access to academic standards across all 50 US states; without it they have to be adapted by hand. The plugin's .mcp.json lists nine more external MCP servers for teachers: ASSISTments, Brisk Teaching, Canva, Coteach, Diffit, Eedi, MagicSchool, Snorkl and TeachFX. Documents come out as Word files or Claude Docs pages. The evals folder holds CSV quality rubrics for each skill, meant as criteria for a model or human judge.
Who it is for. US school teachers and instructional coaches who prepare lessons in math, English, science and social studies and work in Claude Code or Claude for Teachers.
Good fit when
- Tomorrow's fifth-grade lesson is on long division and you need a plan with handouts and an observation sheet.
- An existing lesson must be split into three levels of difficulty and given a version for a student with specific needs.
- A teacher wants to walk through the key task of a lesson in advance and see where a student would give an almost-right answer.
- Before a new topic you want a short math check whose options come from typical misconceptions.
- A team writing its own education skills needs rubrics for scoring the output.
Not a fit when
- You need grading, a student-facing rubric or a scored quiz: the skills create lesson materials and do not grade.
- The check is for a subject other than math: k12-check-for-understanding is built for math only.
- The school is outside the US and state standards do not fit: without the connector you must supply standards by hand.
Example request

Plugin version 0.10.0 targets US academic standards and reaches them through the Learning Commons Knowledge Graph connector. That connector ships with Claude for Teachers; elsewhere access has to be set up separately.
Documents are built as Word files or Claude Docs pages, depending on what the conversation can produce.
The third-party MCP servers in .mcp.json run on their owners' side and need a sign-in to their services.
How to disable. Run claude plugin uninstall k12-education, or delete the cloned repository and the added marketplace.
FAQ
How do I install the plugin in Claude Code?
Clone the repository, add it as a marketplace with claude plugin marketplace add ./k12-teacher-skills and run claude plugin install k12-education@k12-teacher-skills.
Do I need a Claude for Teachers account?
No. Claude for Teachers has the skills preinstalled, while elsewhere you load them by hand as a plugin. In that case adapt them for the missing standards connector.
Which subjects do the skills cover?
Lesson plans and differentiation work with math, English, science and social studies. The check for understanding covers math only.
What is the evals folder for?
It holds CSV rubrics with quality criteria: pedagogy, rigor, formatting and model scaffolding. Paste them into a judge-model prompt or apply them by hand.
Which external services does the plugin connect?
The .mcp.json file lists nine HTTP servers: ASSISTments, Brisk Teaching, Canva, Coteach, Diffit, Eedi, MagicSchool, Snorkl and TeachFX. The user enables them.
