The Council of the District of Columbia enacted the DC Public Education Reform Amendment Act of 2007. This act established a DC public school agency based on authority given to the council in the District of Columbia Home Rule Act of 1973. The Department of Education that was established under the Mayor triggered several changes. The largest was already discussed—DCPCS gained sole authority over chartering and charted schools, DCPS became subordinate to the Mayor's office. Secondly, many smaller authoritative changes took place. The first is that the State Education Office (SEO) became the State Superintendent of Education (OSSE). The four subsections of the District were reaffirmed through location-based State Board of Education selectees. In addition, the smaller eight school election wards were reaffirmed. Finally, the commission was established through this legislature. The "Commission" is the Interagency Collaboration and Services Integration Commission, which includes the Mayor, Chairman of the Council of the District of Columbia, Chief Judge of the DC Superior Family Court, Superintendent of Education, Chancellor of DCPS, Chair of DCPCSB and fourteen others.
