LDC works to eliminate literacy-based opportunity gaps, especially for historically marginalized communities, by guaranteeing access to rigorous Tier 1 instruction that builds students’ strategic and metacognitive thinking. LDC’s instructional systems approach integrates all three, typically siloed, instructional subsystems (curriculum, assessment, and professional learning) to support effective disciplinary literacy instruction aligned to ELA, science, and social studies standards. LDC leverages technology to strengthen teacher practice and verify student learning outcomes.
