Common initialisms
AI | Use artificial intelligence. AI may be used in subsequent references. |

ASU |
On first reference, use the full name of the university: Arizona State University. Use ASU in subsequent references, but do not introduce it as an abbreviation in parentheses. Not: Arizona State University (ASU). An exception to using the full name on first reference may be made in internal publications, published under an ASU masthead, and when there is no question as to who owns the content.

POS, iPOS |
A Plan of Study is a list of courses and culminating experience which maps the requirements for completion of a degree program. The POS is submitted and revised electronically via the iPOS system, or the Interactive Plan of Study. Once the POS is submitted, it becomes a student’s official plan of study.
As clearly as possible, distinguish between the plan, POS (whether unofficial or official), and the method of submitting, iPOS, the official version.
Spell out the phrase on first reference and use the POS or the plan thereafter; do not use parentheses.
