A
Starfleet officer, in 2364, Chang conducted the
Starfleet Academy entrance exam on
Relva VII. Chang administered a variety of academic tests and psychological evaluations to four finalists, including
Wesley Crusher. Chang presided over Wesley's first attempt to join the academy. But Chang could pick only one candidate, and that honor went to
Mordock, who became the first
Benzite to enter
Starfleet.
