A regional office of education (ROE), sometimes called a regional superintendent's office, is a level of educational administration in Illinois. Each one has an educational service region, or simply region, consisting of one or more counties,[1] and supervisory jurisdiction over the school districts lying primarily in that county or those counties.[2] The office is primarily under the control of a publicly-elected "regional superintendent of schools", formerly known as the "county superintendent of schools",[3] but also has a publicly-elected "regional board of school trustees", formerly known as a "county board of school trustees".[4]
