# State standards knowledge graph tool in Playlab
> Access comprehensive state educational standards through AI-powered knowledge graph queries including Common Core, NGSS, and WIDA
🧪 This feature is currently in BETA and available to all users
## What is this feature?
The State Standards Knowledge Graph Tool transforms your Playlab apps by providing direct access to a comprehensive database of educational standards including Common Core State Standards (CCSS), Next Generation Science Standards (NGSS), and WIDA English Language Development standards. Rather than relying on generic AI responses about educational standards, your app can now query specific, standards-aligned content that understands how every standard connects within state frameworks.
Enabling this tool will modify your app's behavior to prioritize specific state standards queries over general educational responses.

How to leverage State Standards
## Setup Instructions
Navigate to the **Tools** section in your Playlab builder interface.
Select **State Standards Knowledge Graph Tool** from the available MCP tools list.
Add these instructions to your Playlab app prompt for optimal performance:
```text theme={null}
You have access to the State Standards knowledge graph tool for curriculum-specific queries. When users ask about educational standards, alignment requirements, or standards-based content, prioritize State Standards results over general knowledge.
You can reference specific standards codes and alignment information to enhance explanations with accurate standards-based content.
When searching for the correct standards document, use the get_documents_by_state operation.
```
Validate the tool works correctly by testing various query categories:
**Standards Queries:** "Find Common Core math standards for 4th grade fractions"
**Science Standards:** "What NGSS standards cover ecosystems in middle school?"
**Language Standards:** "WIDA standards for academic writing proficiency"
**Cross-Standards Alignment:** "How do Common Core and NGSS align in elementary grades?"
Refine your app instructions based on testing results to maximize the tool's effectiveness for your specific use case. Pay attention to which operations work best for your app's workflow and include explicit guidance in your prompts.
## Understanding Standards Knowledge Graphs
### What Makes This Different
A standards knowledge graph goes beyond simple content storage. It maps the relationships between educational standards, learning objectives, and assessment criteria in ways that mirror how educators design curriculum and instruction.
### The Standards Advantage
This knowledge graph captures the interconnected nature of educational standards across subjects and grade levels. It understands:
* **Vertical Alignment:** How standards progress from grade to grade
* **Cross-Curricular Connections:** How standards connect across subject areas
* **Assessment Alignment:** How standards align with state assessments
* **Implementation Guidance:** Best practices for standards implementation
## Subjects & Standards Coverage
### National Standards Frameworks
Comprehensive mathematics and English language arts standards for grades K-12, adopted by most U.S. states
Three-dimensional science standards emphasizing scientific practices, crosscutting concepts, and disciplinary core ideas
English Language Development standards supporting multilingual learners across content areas
Spanish Language Development standards supporting Spanish-speaking multilingual learners
### State Subject Areas
The tool provides access to standards across four core educational areas:
* **English Language Arts**
* **Mathematics**
* **Science**
* **Social Studies**
Coverage spans participating U.S. states **plus Washington, D.C.** Select your state — or **D.C.** — in the state filter to pull the matching standards into your app.
For each State-Subject pair, there is a dedicated "document" that contains the standards information. In some cases, like Pennsylvania Social Studies, there are several documents within a single state-subject combination.
## Current Gaps in Coverage
* New Jersey → Math
* Arkansas → English
* Iowa → English
* Minnesota → English
* South Carolina → English
* Alabama → Science
These documents will be added in future updates to the knowledge graph.

## Frequently Asked Questions
The knowledge graph includes standards for English, Math, Science, and Social Studies across participating states and Washington, D.C., plus national frameworks including Common Core State Standards for Mathematics and ELA, Next Generation Science Standards (NGSS), WIDA English Language Development standards, and WIDA Spanish Language Development Standards (Marco DALE). Note that some state-subject combinations are temporarily missing from the current database.
The tool is currently in BETA with some known performance characteristics:
**Tool Call Reliability:** You may notice the tool requires multiple calls to find the correct information due to formatting inconsistencies across states. An update to the knowledge graph is expected in the next few months that will improve tool call dependability.
**Inconsistent Formatting:** One of the biggest limitations is inconsistent formatting from one state-subject to another. For example, the tool may attempt to filter by grade level, which won't work for some documents that organize grades differently because:
* Grade level attributes might not exist in some documents
* Grades might be written as "middle school" or "grades 3-5" rather than the expected list format (e.g., \[7,8,9])
* Different states use varying organizational schemes for the same content areas
**West Virginia Mislabeling:** West Virginia standards documents are incorrectly listed with `state="Virginia"` in the system. The tool can usually recognize and correct this error automatically, but you may see Virginia results when searching for West Virginia standards.
**Varied Organizational Schemes:** Different states organize their standards using different structural approaches. Some documents use domains/clusters organization while others employ different hierarchical structures, causing inconsistent knowledge graph traversal when moving between state-subject combinations.
The knowledge graph reflects the most recent versions of each standards framework, including the 2020 WIDA ELD Standards Framework and current NGSS performance expectations, ensuring you have access to the latest standards requirements.

**Tier 1 Performance (Recommended):** Claude Sonnet 4.6 (excellent balance of speed, accuracy, and standards analysis), GPT 5.4 (superior for complex standards alignment and detailed responses), Gemini 3.1 Pro (high accuracy with comprehensive educational standards analysis), and Gemini 3.5 Flash (frontier-tier agentic performance at Flash-tier speed, strong for multi-step standards alignment workflows).
**Tier 2 Performance:** Claude Opus 4.6 (most thorough standards analysis but slower response times) and Kimi K2.5 (advanced tool usage with solid educational standards handling).
**Speed-Optimized Options:** Claude Haiku 4.5 (faster responses with reduced analysis depth) and Gemini 3 Flash (quick queries for simple standards questions).
For most educational applications, Claude Sonnet 4.6 or GPT 5.4 provide the optimal balance of capability and efficiency for standards-based queries.
Yes! The knowledge graph excels at revealing cross-curricular connections, such as how Common Core mathematics standards align with NGSS science practices, or how WIDA language standards support content area learning.
While the tool focuses on the core national frameworks, it includes information about common state adaptations and implementation variations. You can supplement with state-specific resources through Playlab's reference system.
The tool helps identify specific standards codes, understand grade-level expectations, find prerequisite skills, and discover cross-curricular connections to support comprehensive standards-aligned lesson design.
Absolutely! The knowledge graph includes information about standards-aligned assessment practices, performance indicators, and evaluation criteria to support both formative and summative assessment design.
Through WIDA standards integration, the tool provides guidance on language development expectations, academic language support, and strategies for integrating content and language learning across disciplines.
Yes! The State Standards Knowledge Graph Tool integrates seamlessly with other Playlab features, including reference files, custom instructions, and existing MCP tools for comprehensive educational support.
