Yes you can. All you need to do is to sign up and then click on your name at the top of the page, select the tab called 'review' and then choose the review you want to change and then edit it. SchoolAdvisor tracks all reviews by your email address so as soon as you sign-up you will be able to see all the reviews you have done in the past.
We know that sometimes suppliers need to know if they are not doing well, and giving a negative but constructive review can be very helpful. Once a supplier has addressed the problem, you might want to change your review.
