Students on Education programmes need to have health clearance before starting placements, you should have been sent this as part of your Admissions process.
If your health situation changes while you are on your course, whether you have fallen ill or are pregnant, you may need a follow up assessment. Please don’t worry about telling the University as there are very few conditions that would stop you doing your course.
Please contact your tutor and they will advise whether you will require another assessment.
