​​​​Shima has held a number of leadership posts at various Maui schools, including vice principal of Makawao/Lahainaluna High School and Wailuku Elementary. He has also served as principal of Kihei Elementary School before starting with the complex area in May of 2011. Shima also served a brief stint as interim principal at Iao Intermediate before being named interim complex area superintendent.

There are 16 schools in the complex, 13 of which feed into the high schools: Henry Perrine Baldwin, King Kekaulike and Maui. The entire complex has an enrollment of more than 16,000 students. Earlier this year, Baldwin High School was part of a triumvirate of schools that swept to the state robotics championship, securing their second appearance in the national robotics competition in St. Louis, Mo. In recent years, both King Kekaulike and Maui High have been named among the most challenging high schools in the nation by the Washington Post.

“Alvin’s experience as an educational leader will be valuable as we prepare for what will be a critical school year for the Hawaii Department of Education,” said Ronn Nozoe, deputy superintendent, Hawaii State Department of Education. “We are moving forward with the department’s Strategic Plan, which has student achievement at its core.”

Shima holds a bachelor of business education and a master’s of education in curriculum and instruction from the University of Hawaii-Manoa.

Shima retired at the end of 2015. Leila Hayashida​ became the CAS for the Baldwin-Kekaulike-Maui complex effective 2016.​
