CLAVES stands for Cultivating Linguistic Awareness for Voice and Equity in Schools. CLAVES is a language-based literacy curriculum designed for upper elementary multilingual students and their peers. In a recent field trial, the CLAVES curriculum was shown to have measurable impacts on language, reading, and writing outcomes for multilingual students. Over the span of three justice-oriented units, students engage in critical discourse and deepen their understanding of vocabulary, syntax, and morphology.
