Aptify's default implementation of the Scantron Import wizard assumes that the file to import is in the standard Scantron fixed-length file format. This means that each column is assumed to begin at a fixed position within the text file. For example, the Last Name column always begins with the 10th character and can consume a maximum of 20 characters.

Note that an organization can configure the wizard to use a different format, if necessary. The wizard's file format is defined in the ScantronImport base class by the ParseScantronFileLine method. An organization can create a sub-class to override this method as needed and add a plug-in object to the Answer Sheets entity. See the Aptify Software Development Kit (SDK) for information on the Scantron Import object (Aptify.Applications.Education.ScantronImport).
