The document discusses the invisibility of social class in adult education. It notes that while race and gender are often considered in diversity efforts, social class is largely ignored. Theoretical frameworks suggest social class disadvantages students throughout the education process through lack of belongingness and feeling like imposters. Low-income students often work full-time to pay for school and lack the social capital and support that wealthier students have. The implications are that adult educators must make social class visible and create supportive environments for low-income students.
