The '60s was a time when students were encouraged to "do your own thing," and Kauaʻi High was a part of that approach to life. Clubs, activities and committees seemed limitless, and at Kauaʻi High School that was just the beginning. They had added numerous clubs, like the National Thespian Society, Explorer Post, Y-Club and lots more. Kauaʻi High School had about 190 seniors in the '60s. As the '70s rolled in, the school's senior class grew to 249 students, and more clubs, activities, sports and classes were added. A homemade dynamite bomb was found in the "K" building boys' restroom and fortunately was defused. The old "A" building was torn down, and there were plans to build a new, two-story, 12-classroom building. In the 1970s they built the cafeteria, library, administration building, "K" building and the swimming pool.
