These are the appendixes for the report, "How Nebraska Teachers Use and Perceive Summative, Interim, and Formative Data." This document presents additional information about the study topic: teachers' data use. It begins with a description of the conceptual framework and supporting literature for the scales in the Teacher Data Use Survey (TDUS; Wayman et al., 2016), which the Nebraska Department of Education (NDE) administered to teachers and principals in March 2019. It then presents literature on teacher and school characteristics that were of interest to NDE as possible factors associated with teachers' data use. Five appendixes are included in the document: (1) About the study; (2) Methods; (3) Supporting analysis; (4) Other analyses; (5) Teacher and principal versions of the Teacher Data Use Survey.
