The lamp symbolizes knowledge and the winged foot symbolizes athletics.  The column represents character.  At the top of the shield is the school's motto, "Lux Et Veritas" - "Light and Truth."

Out by the western plains,
where the sun sets,
There you will see
how the Mighty Bison roam.
With love and honor
we fight and learn greatness,
kindness, dedication, leadership,
These things we have learned.
Brilliance, Resilience
And strength are nigh,
Here in the hallowed walls
of Ronald Reagan Senior High.
