@abc.abstractmethod<EOL><INDENT>def can_delete_assessments_taken(self):<DEDENT>
return<EOL>
Tests if this user can delete ``AssessmentsTaken``.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known deleting an
        ``AssessmentTaken`` will result in a ``PermissionDenied``. This
        is intended as a hint to an application that may opt not to
        offer a delete operations to unauthorized users.

        :return: ``false`` if ``AssessmentTaken`` deletion is not authorized, ``true`` otherwise
        :rtype: ``boolean``
