A part of the Hawaii Department of Education (HIDOE), it was established in 1912 and serves kindergarten through twelfth grade.
The campus boasts an untitled 1977 copper and bronze sculpture by Bumpei Akaji.
Circa 1964 HIDOE closed the Kaupo School in Kaupo due to low enrollment and moved the students to Hana School.
In 2005 Ron Okamura, the superintendent of the Maui division of HIDOE, and Paul jointly decided to send the three students who officially registered at Keanae School to Hana School to conserve resources, although Keanae School was not formally closed.
According to Paul, Hana would have had one fewer teacher in a grade level if the Keanae building had not closed, as there would have been an insufficient number of students in a particular grade level at Hana School.
