The SU Online Technology and Computer Literacy Requirements clearly state that:

Word Processing Program that can create “.docx” files. Only .docx files will be accepted for written assignments and papers.

Why is that?

Our instructors all use one of the most recent versions of Microsoft Word for grading papers and assignments.  When students submit .docx files for assignments and papers, they ensure that the instructor will be able to read and grade their work without any problems.
