The purpose of this qualitative descriptive study was to explore how Nigerian immigrant parents described how they develop successful relationships with their child's teachers in K-12th schools in the Eastern United States. RQ1 guided the study: how Nigerian immigrant parents described their challenges when developing relationships with their child's teachers in K-12 schools. RQ2: How do Nigerian immigrant parents describe the strategies to develop successful relationships with their child's teachers in K-12 schools? 20 Nigerian immigrant parents were recruited using convenient sampling. Data was collected through interviews and two focus groups. A thematic analysis approach was used to analyze the data. The data was coded using an inductive approach, producing 165 codes and creating a codebook. Six themes were identified. Themes for RQ1: Limited understanding of the education system; Lack of Effective Communication and Partnership; Lack of access to relevant information and support. Themes for RQ2: Open and Consistent Communication; Active participation and Engagement with Teachers; Participation in Educational Workshops and Training Sessions. The findings from the study showed that establishing a solid and positive relationship between parents and teachers is vital for ensuring a child's academic success and overall well-being. Additionally, future research should focus on addressing the unique needs of immigrant parents and their children in their host country.
