School psychology is one of the most important fields within applied psychology, which is closely related to education and as a developing specialty it is important to be considered. Taiwan is an important Western ally and is highly developed in many ways. Taiwan is influenced by both Western and Eastern cultures, and this has inevitably impacted the development of psychology, including school psychology. Due to its complicated relations with Mainland China, most studies on school psychology in China do not include information in Taiwan. In addition, worldwide international studies of school psychology also often neglect Taiwan as a country. In other words, most reviews have not offered a systematic investigation of school psychology in Taiwan. The purpose of this article is to review the development of school psychology in Taiwan. The history and background of school psychology is discussed; the current status and developmental stages of school psychology are presented; the preparation of school psychologists, including the roles, functions, and responsibilities of school psychologists are discussed; and current issues impacting school psychology are examined.
