Metadata in the UCARConnect repository use Achievement Standards Network (ASN) identifiers to tag resources with alignments to education standards and learning objectives. ASN provides open access to standardized machine-readable representations of learning objectives published by education agencies and organizations including the World Meteorological Organization, Next Generation Science Standards, and Common Core State Standards. UCARConnect metadata including LAR and nsdl_dc accept ASN standard identifiers as the preferred method to indicate standards alignments.
