Ontario Education Number


Ontario Education Number

The OEN is a unique, numeric identifier assigned to students in Ontario's elementary/secondary education system by the Ministry of Education. The number will be used as the key identifier on a student's school records and will follow the student through his or her elementary and secondary education.

The OEN makes it possible to keep reliable records on the movement and progress of individual students through elementary and secondary school. In addition, it facilitates the analysis of data about education in Ontario. Use of the OEN system and the data it contains is governed by both the Education Act and the provincial Freedom of Information and Protection of Privacy Act.

The implementation of the OEN is part of a comprehensive redesign of the Ministry's data gathering and information management capabilities. The use of the OEN is a necessary pre-condition of these system enhancements.
