The nature of parent-teacher relationships in early childhood programs, including interventions for children with disabilities, is examined within a sociopolitical context across five eras of the twentieth century. Two general approaches are discerned: practices that view parents as learners in need of expert information and advice about child rearing, prevalent through the 1950s, and strategies involving parents as partners with educators in program decision-making, which began to surface in the 1960s. Attention is given to the influence of the Parent Teacher Association in the early 1900s as a response to societal changes stemming from the Industrial Revolution; contributions of the child study movement of the 1920s to parent education activities; effects of the Great Depression on ideas and practices related to individuals with disabilities; the growth of parent advocacy on behalf of children with disabilities; and the influence of the civil rights movement of the 1960s and widespread demographic changes of the 1970s on parent-teacher relationships. Current issues in forming and sustaining parent-teacher partnerships in early childhood programs are identified.
