Not sure what the other reviewer meant. MHS has the highest state assessment (HSA) scores of any high school in Hawaii. All of the MHS AP courses passed the College Board Audit easily. A number of the teachers have national reputations. (e.g. Mrs Tong- ap reader; mrs. Boehning, outstanding History Day Teacher; AP Chem teacher has a doctorate in Chemistry and was a university researcher, etc) Students have been Siemens Science and Math national finalists, History Day national finalists, and winners, Principal is the Hawaii Secondary Principal of the year for 2007-08, and so on.... The school even has a Security Aide/ass't football coach who has two Super Bowl rings.

a. Mililanis Academic program is excellent. they have a varity of courses and most of the teachers are there for your success.
b. Their availability of extracurricular activities are enough to keep your student in a safe school environment but they are smart enough to know when to not cross the line. They keep their activites school related and try to base of an educational message to those activities, so not only are they fun but also educational.
c. Mililanis academic and athletic awards are superb. Athletes are ALWAYS required to keep a grade average over 2.5 and no grades under a D. This way students who are involved in sports still keep their focus on their grades and still get to get out and represent for the school!!
d. The facilities are so-so. While having a good education system and athletic department the school could do a little better in this department. The school is famous for it's own red dirt but the bathrooms could be taken care of much better. Maybe they could buy actual toilet paper instead of napkins?
e. Parent involvement is a necessity. Since the parents are looking out for their kids grades and well-being there are many activities that involve parents to be involved with their children.
