Which organization established the precedent for a children's court in 1906?

The organization that established the precedent for a children's court in 1906 is the Georgia General Assembly. In that year, the Assembly enacted legislation that led to the creation of a specialized court system intended to address the unique needs of children and juvenile offenders. This was a significant development in the legal landscape as it recognized the importance of treating minors differently from adults in the judicial system, considering their particular vulnerabilities and potential for rehabilitation.

The other options, while related to child welfare and juvenile justice in Georgia, do not specifically relate to the establishment of the children's court. The Georgia Juvenile Court System was developed later as a result of the groundwork laid by the General Assembly's initial actions. The Georgia Families Association and the Georgia Child Welfare Board are organizations focused on family and child welfare, yet their roles do not directly correlate with the legislative actions taken by the General Assembly that established the court system dedicated to children.
