This article seeks to present a model of critical factors that influence writing transfer by exploring and extending conversations happening in the field. The article identifies five critical and interconnected factors that support writing transfer: connection, perception, reflection, disposition, and fortification. These factors emerge from an integration of writing transfer scholarship and data from a longitudinal study of student writers. In that study, six participants were followed for seven years (from first-year composition past graduation and into the workforce) and asked to explain their experiences and perceptions of writing. I offer these five factors to spark a broader conversation about how multiple overlapping influences contribute to writing transfer and to encourage further research into how these factors interact and reinforce one another.
