An educational agency in Arizona is seeking a qualified vendor to provide a supplemental K–12 English language development curriculum solution for a one-year contract. The sought-after curriculum must support English language proficiency development across listening, speaking, reading, and writing domains. The resource should focus on academic language growth, vocabulary expansion—including both general academic and content-specific terms—and the development of language structures such as syntax, morphology, and grammar.

Additionally, the curriculum should foster oral language skills and discourse practices, and offer language supports for integrating English language development within content-area instruction. Progress monitoring tools for tracking English language proficiency are required. The solution must include instructional content for at least a portion of K–12 students, align with research-based principles in second language acquisition, and possess strong evidentiary support. Resources must address differentiation to accommodate diverse learner needs. Vendors should note that all inquiries are to be submitted by February 23, 2026.
