Effort reporting is the mechanism used to confirm that salaries and wages charged to each sponsored agreement are reasonable in relation to the actual work performed. For an effort report to be certified, it must reasonably reflect the activity for which the employee is compensated by the institution. Cost sharing commitments must also be confirmed, either through the effort report or through some other reporting mechanism.
Federal regulations require institutions receiving federal awards to maintain systems and procedures documenting the distribution of activity, and associated payroll charges, to each individual sponsored agreement.
Any person paid (or with a commitment) on a federally sponsored award must certify that the salary paid (or the commitment) is reasonable in relation to the effort (activity) devoted to the award. While it is preferred that the individual faculty or staff member report his or her own effort, if necessary a "responsible person with/using suitable means of verification that the work was performed" may report for the individual. The PI of record in Banner will be required to certify for all graduate students paid on their grants.
As soon as you determine that your payroll has been incorrectly charged to a budget, you should notify your departmental payroll administrator to initiate a labor redistribution.
