Throughout the U.S.-affiliated Pacific Region, teacher absenteeism has posed a long-standing challenge. This report draws on research literature from international contexts and case studies to identify the underlying factors that may relate to teacher absenteeism. Resources included in this report were selected with a focus on non-U.S. Pacific entities and emerging economy contexts that might be most relevant to the U.S.-affiliated Pacific Islands. Different search parameters were used to determine the scope of U.S./international literature to include in the review. The report found five main themes to consider in relation to teacher absenteeism: pay structure (for example, direct or indirect working relationship with the school), management (for example, school governance), working conditions (for example, school culture or single- vs. multi-grade classroom structure), community conditions (for example, teachers' proximity to the school), and social and cultural responsibilities (for example, illness, funeral attendance, and care of family members). Predictors of absenteeism vary across place and context. Given the diversity of Pacific Region communities, stakeholders should examine the extent to which the context and results of the research in this review correspond to the social, structural, cultural, and environmental characteristics of their own contexts. The following are appended: (1) Data and methodology; and (2) Viewing absenteeism through an international lens. A list of selected literature on teacher absenteeism in the United States is also included.
