Change description : 2026-02-12 09:00:00: Updated for the academic year 2025 to 2026. Changes reflect dates for this academic year, the common transfer file (CTF) 25 specification, and the move from the Primary Assessment Gateway to the National Curriculum Assessments Portal (since Pearson has been providing the Test Operations Service on behalf of STA since September 2025). The format of the guidance has also been updated to meet accessibility regulations – this is now in HTML format with the example file structure for XML returns as a separate downloadable ODS file.
