Classes differentiate into four performance levels. As of 2010-11, MAP (Measures of Academic Progress) test results are considered for placing incoming students; as of 2013-2014, PSAT and AP Potential results are also factored in. The levels include:

International Baccalaureate (IB):

Introduced in 2006, the Diploma Programme IB courses at NOVA are part of an academically rigorous college bound IB Diploma Program for the internationally minded students.

Advanced Placement (AP):

Introduced in 2001, there are over 20 AP courses offered. AP courses are preparatory or university level courses that may earn student’s college credit at North-American, Western European and Australian universities.

Honors/Advanced (H/Adv): Students scheduled at this level have demonstrated distinct aptitude and skill within this rigorous academic program. The curriculum includes the application of independent study and individual research work. Currently courses in the subject areas of English, Mathematics, PE, Art; Biology, Chemistry, Physics are offered at this level.
