Studies show that effective partnerships between schools and families improve students' academic outcomes. Schools often struggle to implement effective strategies with low-income families, however. This multiple case study examines family-school partnership activities at eight demographically diverse schools in the state of Hawai'i and examines successful family outreach strategies that cut across socioeconomic status. Drawing from interview transcripts, which were selectively coded, the study identified successful modes of communication as identified by participants. Overall, participants reported that personalized, informal, and face-to-face communications were the most effective modes of communication. These findings have implications for K-12 teachers' online communication with families.
