I need a reasonable adjustment, is this possible and how do I request one?

Yes, if you feel you need an adjustment to complete the assessment, please make sure to inform the prospective employer (i.e whom you are applying for a role with) before you start the assessment. 

You will find helpful information in your assessment invitation. Your invitation email provides you with your personal ID, the deadline, average time to complete the assessment, an overview of what the assessment involves, a link to a practice assessment and information about how to request a reasonable adjustment.
