The process through which one receives assurance that work was performed so as to provide a certification of effort on the periodic effort reports. This process must take into consideration other university records and provide for the documented review of such records in support of work performed. Some examples of these records might include: calendars, teaching schedules, logbooks, or sponsor budgets. Other means of verification may also suffice, including e-mails attesting to effort devoted based upon firsthand knowledge. Oral verification from the employee/Principal Investigator or others fulfilling the role of a responsible person to an administrator will not suffice as a suitable means of verification.
