Double Marker: CSV format

To get your school set up smoothly, we need a CSV or Excel export of your student data. This page outlines the exact columns we need and how to format your files for a successful upload.

Your file should be saved as a standard spreadsheet (like a CSV or Excel file) with the following headers in the top row.

Column Header	Status	Description
Identifier	Optional	Your school's internal reference (e.g., Exam Number, UPN, or Admission Number). While optional, it is highly recommended so you can easily link this data back to your own MIS.
First Name	Required	The student's given name.
Last Name	Required	The student's family name or surname.
Class Group	Required	The student's current form, registration group, or class (e.g., `10A`).
Date of Birth	Required	Standard date format, ideally `YYYY-MM-DD`.
Gender	Required	The student's gender (e.g., `F`, `M`).

Here is an example of exactly how your data should look before uploading. Ensure your headers exactly match the first row shown below:

Identifier,First Name,Last Name,Class Group,Date of Birth,Gender
