"At UHM, the average six year graduation rate is 54%. Native Hawaiians are least likely to graduate in 6 years (42.0%) indicating that they are less likely to complete degree requirements compared to other ethnicities.

According to 2000 UHM data, approximately 41.3% of the Native Hawaiian students at UHM graduated within six years compared to 73% among Chinese and 
64.2% among Japanese given the same time frame. Among the Native Hawaiian who do graduate, they generally take
longer, moreover, the longer it takes to graduate the least likely it is that a degree will be earned."
