The header position is fixed. Maybe you can begin the header text with several blank lines to move it down.

Moving the header down is a good workaround. Thanks!

I finally had a chance to test this workaround, and unfortunately it doesn't work.

Extra whitespace is removed before placing the header on the page. So simply inserting blank lines doesn't have any effect. I tried a number of other workarounds. I added some TeX code to insert vertical space, but it was copied verbatim to the header. I add a column "blank" to the student list where each entry was a single space, then inserted %(blank) into the header. That whitespace was stripped too.

In the end I inserted some lines with a single | character. That makes a mark on the page but at least moves the header down below the logo.

Can this be considered as a feature request?

Sure. I think a command like \namefield should be available to define in the LaTeX source file where global annotations should take place.
