Sorry, no substitutions!
Something to be aware of during your qualifying period for tenure or promotion is that no special arrangements can be made regarding meeting the standards. As a hypothetical example, suppose a Dean asks you to become a Department Head and offers to champion your promotion/tenure case if your research suffers as a result.
However vigorously that Dean champions your case, the collegial committees nonetheless are obligated to decide whether you meet the standard in all the categories. In the above hypothetical example, make sure that you receive sufficient release from other duties to allow you to meet the standard.
