*The closing date for parents to enter via the PPS is at the discretion of the school. The date listed above is the last possible date the PPS can remain open for parents.
The PPS allows parents to register and pay for their children’s ICAS entries. That means no data imports and no money collecting for schools.
ICAS is a meaningful academic challenge and nationally recognised achievement. Get valuable insights for schools and build genuine confidence for students.
