CIOT and ATT partner with TestReach to enhance exam experience
27 October 2025

CIOT and ATT have agreed a deal with software provider TestReach to improve the exam process for our students from 2026 onwards. The collaboration will provide improved platforms and interfaces for the delivery of CIOT’s and ATT’s Chartered Tax Adviser (CTA), Advanced Diploma in International Taxation (ADIT) and Taxation Technician (ATT) qualifications.

This new agreement follows feedback from students through CIOT and ATT student surveys, and responses to the CIOT’s CTA review consultation earlier this year. Many students commented on the usability of the the current exam platform, Exam4, and asked that we make improvements.

Commenting on the planned changes, Vicky Purtill, Director of Education at CIOT and ATT, said: ‘We are always keen to receive feedback from our students and other stakeholders. This partnership with TestReach is a vital step in futureproofing our qualifications. We needed a modern, secure system that not only safeguards the integrity of our assessments today but also positions us for the future as we design and roll out new qualifications.’

The new TestReach platform will include integrated Microsoft Word and Excel, enabling students to complete exam responses using tools that closely mirror real-world tax practice. The platform also features a clean, intuitive interface, ensuring improved accessibility and usability for all candidates.

For those sitting ATT and ADIT exams remotely, TestReach also offers enhanced support during the exam onboarding and throughout the exam process. The CTA exams will continue to be delivered in centres.

The roll-out schedule for TestReach across our written tax exams is planned over the next year as follows:

  • ATT: May 2026
  • CTA: November 2026
  • ADIT: December 2026

Only exams currently delivered via the Exam4 platform will be moving to TestReach. Our Law, Accounting, and Professional Responsibilities & Ethics computer-based exams will continue to be delivered via Prometric.

Further information will be made available to students as we approach the launch of the new platform.
