**The following FlexBooks are available for use this coming school year. They are available as PDF downloads, though some are already fully loaded on CK-12’s official FlexBook System. We are making these books available NOW, even though they are works in progress, so teachers can preview them for early adoption. If you have any questions, please send them to info@ck12.org.**

CK-12 Foundation and Leadership Public Schools (LPS) have partnered to introduce College Access Readers. CK-12 provides the content and platform for low-cost, mass-customization in textbooks. LPS brings to the table instructional expertise and a real-world incubator for urban education. Together CK-12 and LPS are creating a line of curriculum resources tailored to the most challenging demographic in California and the nation. We call these resources “College Access Readers.” Available as a PDF here.
