Usually S1–S3 (third and fourth levels are both covered in S1–S3) (a guide, not a fixed year group). Roughly US Grades 7–9 (approximate).

Curriculum for Excellence levels are a guide, not year groups: learners move through levels at their own pace. Third and fourth levels are both covered in S1–S3; schools decide the pace.

Plan the whole year: open this course in the Year Planner – every lesson dated around your term dates, with a coverage check. Free.
