The Beal Bank USA Southern Nevada Regional Science & Engineering Fair promotes an interest in STEM for elementary, middle, and high school students in Southern Nevada counties including Clark County and the Clark County School District. Held at UNLV and hosted by the UNLV College of Sciences, the fair is sponsored by Beal Bank USA.

The fair is divided into three divisions: elementary (grades K-5), middle school (grades 6-8), and high school (grades 9-12). Affiliation with the International Science and Engineering Fair (ISEF) requires that high school students follow guidelines established by the ISEF. Rules for the elementary and middle school divisions are determined by UNLV and are consistent with but not identical to (made age appropriate) the rules for the high school division.
