A year of distance learning under COVID-19 has fueled growing concerns about the academic progress and social and emotional health of children. In particular, worries increased around how the pandemic has affected high-need and underserved students, including English Learners and children with disabilities, children in foster care and from low-income families. Distance learning has further revealed how unevenly educational resources are distributed--from access to internet and devices, to teacher instruction and parental involvement--a situation that may expand California's longstanding racial and socioeconomic divides. In the full report to these technical appendices, the authors share the results of their survey of California school districts and their approaches to student learning during the pandemic--whether in-person, hybrid, or virtual. The following three technical appendices to the full report are presented: (1) PPIC Distance Learning Survey; (2) Additional Tables and Figures; and (3) Survey Instruments.
