Sarah Tantillo consults with schools (especially urban schools) seeking to improve student achievement. She taught high school English and humanities in both suburban and urban New Jersey public schools for fourteen years, including seven years at the high-performing North Star Academy Charter School of Newark, New Jersey, where she chaired the Humanities Department and her students achieved a 100 percent passing rate on the High School Proficiency Assessment (HSPA) for Language Arts and Literacy. In addition to teaching, she also founded the New Jersey Charter School Resource Center and the New Jersey Charter Public Schools Association. She led the Resource Center from 1996 to 1999 and the Association from 1999 to 2003. Since 2007, she has coached K-12 schools on literacy instruction, curriculum development, data-driven instruction, school culture-building, and strategic planning. In 2009, she launched The Literacy Cookbook Website (https://www.literacycookbook.com) to provide teachers and school leaders with practical resources and strategies for literacy instruction. That Website formed the basis for her first book. Tantillo earned her B.A. from Princeton University, her M.Ed. from Harvard University, an M.A. from Johns Hopkins University, and her Ed.D. from Rutgers University.
