A new version of this site was created, following the June 24 Bylaws update. This is now the ARCHIVED site.
While not explicitly required, the standard has been to include up to three colleague evaluation letters, solicited from junior or senior faculty on or off campus who may speak directly to your professional work in teaching, service, and/or scholarship. As recommended (but not required) by the bylaws, "[t]hese letters ... are most likely to be helpful when they come from faculty members who are outside the candidate’s Program Evaluation Committee." Colleague letters may also come from individuals outside of the College, but should not be confused with external evaluator letters (see the separate section of this site for those being evaluated for tenure or full professor).
Colleague letters should include a signature (ink or electronic -- but an email isn't suitable), and may be addressed either to "Dear evaluating committees," or to the department chair. It's advised to solicit these letters early in the preparation of your file, with occasional friendly reminders and a clear deadline in advance of that for the file itself. Also, advise your colleagues that unlike a more formal letter of recommendation, this is not a confidential document and will be submitted directly to you. The candidate may review the colleague letter in advance of file submission and decide whether or not to incorporate it.
For ease of inclusion, begin to collect these letters in PDF or Word format in a Google Drive Folder that you name "Colleague evaluation letters." Add that folder on this page using the "Insert" menu, under "Drive Folder." As additional letters are added, they will automatically be updated on this page.
