</Accordion>

<Accordion title="Do I need to pay to use Learning Commons tools?">
  No. Creating a [Learning Commons Platform](https://platform.learningcommons.org/) ↗ account is free and gives you full access to Knowledge Graph and Evaluators. Most Knowledge Graph datasets and all Evaluators are openly licensed and free to use. A small number of gated Knowledge Graph datasets may require users to accept separate licensing terms and fees from the dataset publishers.
</Accordion>

<Accordion title="Do I have to use both Knowledge Graph and Evaluators?">
  No. Knowledge Graph and Evaluators serve different stages of an AI content generation pipeline and can be used independently.

  | Tool                                                                            | When to use                                                                                     | Description                                                                                                                            |
  | :------------------------------------------------------------------------------ | :---------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------- |
  | [**Knowledge Graph**](/knowledge-graph/understanding-knowledge-graph/use-cases) | Before or during content generation — to ground your AI with structured, standards-aligned data | Input-side tool that gives your AI structured, standards-aligned data to work with                                                     |
  | [**Evaluators**](/evaluators/understanding-evaluators/use-cases)                | After content generation — to score output against pedagogical criteria                         | Output-side tool that scores the content your AI produces against pedagogical criteria like grade-level appropriateness and vocabulary |

  With that said, many teams find value in integrating both tools – Knowledge Graph to ground content generation and Evaluators to verify the output.
</Accordion>

## Learning Commons Platform

<Accordion title="Why do I need a Learning Commons Platform account?">
  Your [Learning Commons
  Platform](https://platform.learningcommons.org/) ↗ account allows you to:

  * Demo our evaluators in the [Evaluators Playground](/evaluators/getting-started/quickstart#evaluators-playground) ↗
  * Explore our datasets using the [Knowledge Graph Explorer](https://platform.learningcommons.org/apps/knowledge-graph/explorer) ↗
  * [Generate API
    keys](/api-reference/platform-api/overview) ↗ to integrate Learning Commons
    tools into your project
</Accordion>

<Accordion title="Why do I need an organization associated with my Learning Commons Platform account?">
  The [Learning Commons
  Platform](https://platform.learningcommons.org) ↗ manages
  access to API keys, gated datasets, team collaboration, and permissions by organization.

  You will be prompted to create your organization when first signing in to your Learning Commons Platform account. Any
  API keys you create will be linked to that organization automatically.
</Accordion>

<Accordion title="My API keys are linked to the wrong organization. What can I do?">
  Unfortunately, API keys can't be transferred between organizations. You'll need to create new API keys in the correct organization and update your projects to use them.

  Your old API keys will continue to work until you manually delete them, so you can migrate at your own pace.
</Accordion>

## Knowledge Graph

<Accordion title="Why should our team integrate Knowledge Graph?">
  With our datasets, edtech developers can more reliably produce AI-generated educational content that:

  * Aligns to academic standards
  * Incorporates high-quality curricula
  * Is rooted in learning science
  * Can be translated across states

  Check out [some common use cases](/knowledge-graph/understanding-knowledge-graph/use-cases) of Knowledge Graph before getting started.
</Accordion>

<Accordion title="Can I use Knowledge Graph with any LLM?">
  Yes. Knowledge Graph is LLM-agnostic — you can use it with OpenAI, Google, Anthropic, or any other provider.

  If you're building an agent-based workflow, the [MCP server](/knowledge-graph/using-knowledge-graph/mcp-server) makes it simple to work with Knowledge Graph Data. You can use it directly with the LLM's API or SDK (e.g., [Messages APIs](https://platform.claude.com/docs/en/build-with-claude/working-with-messages) or [Agents SDK](https://openai.github.io/openai-agents-python/)) or with a coding agent (e.g., Claude Code, Codex, or Cursor).

  See [Agent plugins](/knowledge-graph/using-knowledge-graph/agent-plugins) and [Agent Skills](/agent-skills/) for more information.
</Accordion>

<Accordion title="What Knowledge Graph datasets are available now for my region?">
  Knowledge Graph covers all 50 US states, with availability varying by dataset and subject. We do not currently offer international coverage.

  | Dataset                                                                                  | Coverage                                                                                                                                                                                                             |

  Contact [support@learningcommons.org](mailto:support@learningcommons.org) ↗ if you need help finding data for your region.
</Accordion>

<Accordion title="Can I request a dataset or standard that isn't available yet?">
  Yes. We actively expand Knowledge Graph coverage based on demand.

  Share your datasets and standards coverage requests with us at [support@learningcommons.org](mailto:support@learningcommons.org) ↗.
</Accordion>

<Accordion title="How long does integration take?">
  You can get up and running with Knowledge Graph in minutes, using one of our [4 access methods](/knowledge-graph/understanding-knowledge-graph/introduction#how-to-access-knowledge-graph).

  Check out our [Quickstart](/knowledge-graph/getting-started/quickstart#steps) for more information.
</Accordion>

## Evaluators

<Accordion title="Why should our team integrate Evaluators?">
  AI often fails educators in predictable ways (e.g., grade-leveling text, aligning to standards, etc.). Our evaluators address this known credibility gap:

  * Validated against [expert-annotated datasets](/evaluators/dataset/introduction)
  * Grounded in human expertise, learning science, and academic standards
  * Provide actionable guidance on filling the gaps in your AI-generated content

  Check out [common use cases for Evaluators](/evaluators/understanding-evaluators/use-cases) to get started.
</Accordion>

<Accordion title="I already have an evaluation process – why should I integrate your evaluators?">
  Our evaluators allow you to incorporate standards-aligned educational data into your AI content generation pipeline – all without having to rely on slow and expensive human evaluation.

  Our evaluators are also interoperable with many industry tools (e.g., [BrainTrust](https://www.braintrust.dev/) ↗, [LangSmith](https://smith.langchain.com/) ↗, [Arize](https://arize.com/) ↗, [LangWatch](https://langwatch.ai/) ↗, and [Langfuse](https://langfuse.com/) ↗), so you don't have to completely overhaul your tech stack.
</Accordion>

<Accordion title="Our team has unique requirements and constraints for evaluation. Will your evaluators meet our team-specific needs?">
  Most users' requirements can be generalized relatively easily, and it is unlikely that your team's unique setup will degrade the accuracy of our evaluators' output.

  Reach out to [support@learningcommons.org](mailto:support@learningcommons.org) ↗ if you have further questions about integration.
</Accordion>

<Accordion title="How does Learning Commons handle the content I send to evaluators?">
  You retain ownership of any content you submit to Learning Commons evaluators.

  Learning Commons uses your submitted content as described in our Terms of Use and Privacy Policy to provide, operate, develop, and improve our services. Some evaluators rely on third-party large language model (LLM) providers to generate evaluation results. When an evaluator uses one of these providers, the content you submit is sent to that provider to perform the requested evaluation. Those providers operate under their own terms and privacy practices.

  For more information, see our [Terms of Use](https://learningcommons.org/terms-of-use/) ↗ (Section 3.3) and [Privacy Policy](https://learningcommons.org/privacy-policy/) ↗, or contact [privacy@learningcommons.org](mailto:privacy@learningcommons.org) ↗.
</Accordion>

<Accordion title="What evaluators and datasets are available now?">
  We currently provide the following [evaluator families](/evaluators/understanding-evaluators/core-concepts#evaluator-family) and [evaluator datasets](/evaluators/understanding-evaluators/core-concepts#evaluator-dataset):

  |                        |                                                                                                                                              |

</Accordion>

<Accordion title="How long does integration take?">
  You can get up and running with Evaluators in minutes, using one of our [3 access methods](/evaluators/understanding-evaluators/introduction#how-to-access-evaluators). Check out our [Quickstart](/evaluators/getting-started/quickstart#steps) for more information.
</Accordion>

## Agent Skills

<Accordion title="Who are Agent Skills built for?">
  Agent Skills are for edtech developers who want to use AI assistants to produce standards-aligned instructional materials for teachers.

  While teachers are the end users of these materials, Agent Skills are mostly installed and run in agent environments by edtech developers.

  See the [Agent Skills docs](/agent-skills/understanding-agent-skills/introduction) for more information, or check out the [Quickstart](/agent-skills/getting-started/quickstart) to get started.
