## A CK-12 Case Study

Leadership Public Schools (LPS) is a network of four urban charter high schools in the California Bay Area. The majority of our students enter 9th grade reading far below grade level but all participate in college preparatory courses. Given this reality, LPS leverages CK-12  not only to develop low-cost, tailored textbooks, but also to scaffold these to provide better access for our students.  Specifically, we are embedding literacy scaffolds directly into CK-12 Algebra, Geometry, and Biology materials to create flexbooks we call College Access Readers. Students with higher-level literacy skills use the original CK-12 content flexed to our scope and sequence. The lowest readers will soon access the materials through text-to-speech versions or Spanish translations.
