• sorting said collected data;
• automatically identifying scanned response for a first review, including said collected data, wherein said identifying includes determining whether more than one bubble is filled for a single question;
• automatically forwarding said scanned responses to a first human editor to conduct said first review, wherein said first review resulted in a data entry issued from said first editor, wherein said data entry includes an interpretation by said first editor of whether the bubble on the answer document is marked;
• if said data entry from said first editor differs with the indication for a particular scanned response, automatically forwarding the particular scanned response to a second human editor to conduct a second review, wherein said first editor is different from said the second editor;
• tracking said collected data and controlling to said collected data to prevent said first editor or said second editor from acting as both said first editor and said second editor.
