Make entries with EDI and basedata

How to enter students for exams with EDI (Electronic Data Interchange) and basedata.

How the process works

EDI is the process of setting up your school or college's management information system (MIS) so that it can receive and send your entries in the right format.

We provide you with a 'basedata' file for a series – this is a file that contains all the information you need to make entries for each student, and details about the specification such as timetable and fees. You can import basedata straight into your MIS.

You can then set up and use JCQ's A2C Migration Application and send us the entry data. Use A2C's FAQs to help you.

The basedata files conform to version 14 of JCQ's formats for the exchange of exam related data, which uses the common JCQ data format.

Set up your MIS

To submit your entries through EDI, you'll need to take the following steps.

Download basedata

Our main entries page shows the dates when we will update this page with basedata for each series.

We can only include one discount (or classification) code per award in our basedata.

About zip files

A zip file contains one or more files that have usually been compressed to reduce file size. To open (unzip) such a file with Windows or Apple OS, just double-click on it.

If you aren't using either of these operating systems, you may need to download and install a special piece of software that will zip and unzip files.

If you don't already have one, you can download a free unzipping tool, such as WinZip , WinRAR or 7zip .


Each entry option and a small number of component codes within our basedata have a gradeset code. This code identifies the grades that are available for that entry/component. The spreadsheet of gradeset codes for all awarding bodies is published by JCQ.

Older series are on our basedata archive page.

Time allowed set to zero

Some exam papers have been split into multiple components (eg, section A is a component and section B is a component, but sections A and B are designed to be taken as one exam in a single exam slot).

As in the JCQ formats we’ve set the time allowed for these components as ‘000’.

Students can spend as much time as they want to on each component within the overall exam.
