Subject elective selection occurs at the commencement of Stage 5 (Year 9 and 10) at Scone Grammar School, and again at the commencement of Stage 6 (Preliminary HSC and HSC courses).

Elective subjects offered at Scone Grammar School in Stages 5 and 6 are contingent upon available staff and on the numbers of students selecting each course. The subject selection process occurs for Stage 5 courses at the conclusion of Year 8 at Scone Grammar School, and at the conclusion of Year 10 for Preliminary HSC courses. Newly enrolled students at the commencement of the Year 9 and Year 11 academic years may select their subjects from elective choices available.

Students have up to five weeks to change their subject selection at the commencement of their Year 9 or Year 11 academic year. In most cases, students may change elective courses between Year 9 and Year 10 should they desire to do so.

In Stage 5, students can select up to three subjects in the elective courses that include the following in 2006 / 2007:

In Stage 6, students can select courses to make up their Preliminary HSC / HSC patterns of study that include the following in 2006 / 2007:
