The current alma mater, "All Hail to Thee," was written by members of the Class of 1959 as their gift to NHS as outgoing seniors.

The school offers many extracurricular activities, including athletics, ASB (Associated Student Body), the Mock National Security Workshop, among others.

"The Underpass" Incoming seniors from NHS buy specific spots auctioned near the end of the school year and paint them, adding personal touches, to include whimsical or meaningful images or phrases.

The painting occurs in mid-August; the members of the incoming Senior class decorate their space with artwork of their choice.
