Infrastructure Literacy Curriculum Coding: Three-Layer Content Analysis of Construction Credentials

Three-layer systematic content analysis of construction career and technical education curricula across four credentials in three national systems (United States, Australia, United Kingdom). Layer 0 searches 15 primary environmental justice terms; Layer 1 expands to 30 near-synonyms; Layer 2 thematically audits 344 individual learning outcomes against three binary equity criteria. Finding: zero percent of outcomes address environmental justice, community health equity, or distributional consequences of infrastructure decisions.
