The BC Ministry of Education has recently announced EDX phase 3 starting in early 2026.

We have reviewed the new specifications and have made appropriate changes in WebTess to be compliant with the new requirements.

The DEM, CRS and XAM file formats remain unchanged.

We have made some improvements in the data transfer process to improve data validation:

• The data transfer will only include students from Grades 10, 11, 12, AD, AS, HS and SU. The Ministry has indicated that even if students in earlier grades are taking Grade 10 level (or higher) courses, they should not be included in the data transfer.
• The XAM file contains the data required to register students for BC assessment courses such as LTE10, NME10 and LTE12 (as well as the equivalent French language courses). It will not include previously assigned marks for these courses, but you will be able to import the assessment marks from the Ministry.
• Historical data (any data from previous school years) will no longer be included in the data transfer. This means only courses from the current year will be included in the data transfer. Exceptions can be made for special cases if you need to submit data from previous years that has not already been submitted to the Ministry.

The DEM, CRS and XAM are all in plain-text format, which means you can open them using Notepad (or another text editor) if you wish to check the data in the files before uploading them to the Ministry web-site. Do not use Excel to open or change the files since this will change the formatting.
