Including this statement in your portfolio should remind evaluators that they must not penalize you for not having student evaluations for the periods during which the college did not administer them.
 

The  collective bargaining agreement contain the following provision: 

"(b) Hold Harmless Provision. The Board and the Association state and acknowledge that no student evaluations were conducted pursuant to Article VIII, D1a or 2a during the fall semester or the spring semester of the academic year 1999-2000; and they hereby agree, therefore, that the absence of such student evaluations from the evaluation record of any member of the bargaining unit shall not be considered, either positively or negatively, in the evaluation of his or her teaching effectiveness…. During …[the fall semester, 2000]… the provisions of the preceding sub-section (b) will apply to such semester."

Accordingly, my [reappointment/tenure/promotion/post-tenure review, whichever applies] file has no contractual student evaluations for [list the appropriate years and semesters] The absence of these student evaluations must not influence my evaluation in any way.

My teaching effectiveness is shown by classroom observations, course materials [and my informal student questionnaires and/or comments provided to me by students, if any were used or received].
