This study examines how the Change Communication Model can be used to implement a new student information system (SIS) in a school district. The impetus of the study came from government mandates requiring district accountability through data-driven decision making. Data-driven decision making is only possible when student data are collected, stored, and reported efficiently through SIS programs. As with the implementation of any change, effective change to the use of a SIS occurs when districts address concerns and dynamics identified in theories and models of change. Ellsworth's Change Communication Model is a blending of seven change models. Ellsworth uses components of each model to create a framework for systemic change. This study investigates what change components were instrumental in adopting and implementing a new SIS and how these components aligned with Ellsworth's Change Communication Model. Hall and Hord's Stages of Concern Questionnaire (SoCQ) was used to determine stages of concern for SIS users and identify volunteers for focus groups. Focus groups, individual interviews, field notes, and document review were chosen as methodological tools to gain an in-depth understanding about the factors that affect change during the implementation of a new system. Seven themes that describe major aspects of the SIS change process emerged from the data: the importance of training, positive and negative perceptions of adoption decisions, apprehension about change, perceptions of SIS benefits, user confidence and comfort, the impact of a supportive environment, and feedback loops. Individually and collectively, these themes are related to the change models that comprise Ellsworth's Change Communication Model. This study's findings suggest successful implementation of a SIS occurs when elements of all seven change models within Ellsworth's Change Communication Model are addressed.
