Thank you for your course/exam booking with AEC.

Please note, from 1st March 2025 we will now require BOHS Candidate Information Forms to be sent to us to process your exam booking with BOHS. This form must be completed and returned to training@aec.uk within 48 hours of making the booking, without this form, we cannot order an exam for you. Please note, BOHS will no longer be sending paper exams. All classroom courses will now have a remote exam set up by BOHS. You will need to bring a tablet or laptop with you to complete the exam.

The reason for the above is because BOHS will now be using an online exam software provider, Eva, to provide the function to generate online exams.

This should help speed up the turnaround time for the marking process.

Many thanks

We appreciate your assistance with this matter
