Using endnotes in a teaching statement I've been working on my teaching statement recently (for the mathematical sciences, but it shouldn't matter).  I'd really like to keep the main body to one page, because I personally wouldn't want to read anything longer than that, but there are several instances where I feel like I could include a little more information "for those inclined to read it".  Do you think it is appropriate to include these comments as endnotes, or is this somehow more irritating than having a slightly longer document with such comments incorporated inline? For instance, if I do something like this, I end up with one page of text followed by a half page of notes. 


  I've had broad success1 using a modified Moore method to teach a
  graduate qualifying exam review course.

  1 In the three years I have taught it, 22 students have taken the course, and 19/22 have passed at the PhD level first try; in contrast, the first-try PhD pass rate for the five years prior was only 50%.


If I incorporate such statements, I'm over my (entirely self-imposed) one page limit.
Endnotes of the sort you are suggesting would give the impression that you don't know how to write a teaching statement. In any document like this, you're trying to make a convincing case, which means knowing what to put in and what to leave out.
