TinyMCE and multiple instances of the editor

I am using TinyMCE as the editor. I have a quiz that 8 students have completed that I need to mark. Therefore, the editor should appear 8 times on the page. However, it is loaded 64 times. 8 times for each one of the 8 instances. When there are supposed to be two instances of the editor on the page, it appears 4 times, 2 times for each of the 2. Obviously some instruction is getting sent more than one time.
