Is it appropriate to include additional materials in an academic job application?
Unless the call clearly states that nothing more must be included you should do so. As you correctly identified such information provides insights into you success in teaching. An option could be to simply include a summary in the CV or make it part of the teaching statement, as support that your teaching ideas produce good results. In short, add the material but make sure it is condensed and clearly structured. I have added such material to applications (for promotion in my case) and had someone sign off that the summary reflects the material on which it is based.
