When Kauaʻi High School opened in 1914, it was just a little over a month after the outbreak of World War I. There were seven in attendance that year. Only one of these remained to graduate. The next year seven more entered. For each of the following three years, about twice that number came in. In 1919, 29 entered. Seven students graduated in 1919; numbers climbed to about 100 per class in the 1930s. During the '20s and '30s, some students lived in private dormitories, bungalows were built as classes were added, sports were introduced and students enjoyed dances and theatrical performances. The original school building was torn down in 1931, and the gym (still in use today) was built in 1939.
