Reference Number File

<< Return to Reporting Academic Data

Before each grades file transmission, you may identify university applicants in your school/board file(s). This is done through the “Reference Number File” option in COLS, by choosing “OUAC Reference Number”.

  • The “OUAC Reference Number” file contains OUAC Reference Numbers for the school’s university applicants and is used to update the school’s or board’s grades file. As a result, data is transmitted only for those students who have an active OUAC application.
  • The “OUAC Reference Number” file is not intended for manual updating.
  • If you have questions about importing this file into your system, contact your software supporter.

You must notify the OUAC about any changes to the Ministry of Education Identification (MIDENT) numbers and Secondary School Student Numbers (SSSN) for new students as these numbers are used to match the school/board electronic file to the OUAC database.

You must ensure that students (especially twins) do not share SSSNs and OENs.
