Every Day Counts: Attendance Matters
Competitions have been running between forms and also between Houses, with students awarded points for a week's attendance and their punctuality to lessons.
Stewart Richardson, Assistant Principal for Behaviour and Attendance, said if a student has 80% attendance, it is still the equivalent of one day off per week.
Research shows that students with less than 90% attendance have much less chance of achieving their predicted academic target.
Mr Richardson said: "The idea is to create a bit of competition between Houses, forms and individuals, with the results displayed each week so they can see the running total.
"We have been sending letters out to parents whose children are falling below a certain level of attendance and there's lots going on to make this high profile.
"We encourage parents to make every effort to get their child into school."
Gold, silver and bronze certificates are handed out to those with the best attendance records.
