ok, if it's not a page, what is it, because it looks like a page.
it does say div id content and class = assessments, but I don't see anything related to nodes around the body tags.It could be a page node that uses a php callback. To find out, inspect the source. This line will contain the template name in the class, for example for my page node: <div id="content" class="rpmodule_temple">, the template name for that page is rpmodule_temple.
If you scroll further up, you will see the <body> tag. Within the body tag the class is set to the current node id, and it's parents. In my example:<body class="node21 node14 node16"> For my example the node id for my temple page is 21.
May help, may not.
