Maria,
It is important that your files selected for sample are organized in the same format and all documents not part of the file is provided with the student files. If your auditior provides the list ahead of time you should have the files pulled (or if you store electronically have the files in the appropriate area) and ready to go for the review process. I would have my Policy and Procedure Manual available so the auditors will know how your team processes financial aid requirements. If your campus files a FISAP I would have that pulled and available for the auditors.
Best wishes in your first FA audit and I know you will do great.
Sincerely,
Chyrl Ayers
