Compulsory schooling, child study, clinical psychology, and special education: Origins of school psychology.

The historical development of school psychology is discussed in the context of circumstances and individuals significant to its origins. The contributions of Witmer's clinical psychology and Hall's child study demonstrate how early forms of school psychology evolved from their conceptualizations. Even though the specialty did not achieve a stable national identity until the second half of the 20th century, the provision of psychological services in schools is among the earliest fields of applied psychology and has distinct connections to Witmer and Hall.
