This mixed methods study investigates the factors influencing job satisfaction and retention among early intervention (EI) providers in Washington State. The research aims to provide insights into the challenges faced by EI providers and identify strategies to improve workforce stability within the state's EI system. The quantitative phase of the study included a state-wide online survey to assess the levels of job satisfaction among EI providers and collect demographic characteristics and organizational factors associated with job satisfaction and retention. Next, the qualitative phase used semi-structured interviews to explore the lived experiences of EI providers, capturing their perspectives on the factors influencing job satisfaction and retention, including financial compensation, workload, support systems, and professional development opportunities. Survey results were used to select interview participants and shape interview question. Findings indicate a complex interplay of factors contributing to EI provider job satisfaction and retention, encompassing organizational support, professional growth opportunities, workload management, financial compensation and the impact of work-life balance. The findings from this study have implications for state leaders, policymakers, EI agencies, and EI providers and outline the urgent need to address workforce development and retention efforts. By addressing the multifaceted needs of EI providers, including equitable compensation, enhancing support systems, promoting work-life balance, and fostering professional growth, stakeholders can work towards ensuring a stable EI workforce of diverse and skilled providers, ultimately benefiting the children and families receiving early intervention services in Washington.
