Age and grade guidelines

When students are placed in a grade that aligns with our age and grade boundaries, they are more likely to thrive, as significant differences in age and developmental stages can be challenging for the child and their peers.

Grade placement at CIS is according to age. Children must be the age indicated by 31 August in the year of entry. Our minimum age requirements for entry into each grade level are outlined in the table below.

  1. Children who are 18 months old can join the nursery programme, however, they will remain/continue in the nursery programme again the following school year. 
  2. With the exception of Nursery (where toilet training is included in the programme), children joining our Kindergarten programme must be completely toilet trained.
  3. The Diploma Programme is for students aged 16 to 19. Any age exceptions will be subject to the approval of the Secondary School Principal.

While these guidelines are an indication of the required age for each grade level, CIS will in exceptional circumstances accept students who are up to one year older than the grade level age. This is subject to approval of the School.

Rolling admission

We accept students in Kindergarten to Grade 8 throughout the year, although places are subject to vacancy. Entry into grades 9 and 10 is open until the last Monday in February each school year, while entry into grades 11 and 12 (the IB Diploma Programme) is only open to grade 11 students during the first two weeks of the school year.
