 # Texas TEKS Standards
 
-Complete Texas Essential Knowledge and Skills (TEKS) standards dataset sourced directly from the official Texas Education Agency (TEA) CASE API (v2.1.1).
+Complete Texas Essential Knowledge and Skills (TEKS) standards dataset sourced directly from the official Texas Education Agency (TEA) CASE API. Covers all subjects and grade levels from Pre-K through high school, including CTE pathways.
+
+Intended for use in curriculum planning tools, standards-alignment systems, AI tutoring applications, and educational search/retrieval pipelines.

+## Intended Use
+
+- **Curriculum planning tools** — map learning activities to official state standards
+- **Standards-alignment systems** — tag content, assignments, or assessments to TEKS codes
+- **AI tutoring / LLM applications** — provide structured standards context for retrieval-augmented generation (RAG)
+- **Homeschool management apps** — enable standards-based tracking for Texas homeschool families
+- **Ed-tech search and discovery** — power faceted search over Texas K–12 learning objectives
+
+## Known Limitations
+
+- TEKS standards are updated periodically by TEA. This dataset reflects the API state as of the last update date; it may not reflect recent amendments.
+- `domain` and `cluster` fields are not populated in the current version.
+- CTE contains 21,674 records across numerous pathways and courses—users working with CTE data should expect high volume and granularity.
+- Grade level values are strings and may be numeric (`"3"`), named (`"English I"`), or range-based depending on subject area. Normalize as needed for your use case.
