4. Complete the S1 Option Form

Tip: Use the S1 Option Form as a template to prepare the relevant information before starting the online application on the S1 Internet System.

You would need to prepare the following information:

1. School choices

List your child's 6 secondary school choices in order of preference using each school's 4-digit code.


  • For priority admission to the affiliated secondary school, your child must indicate that school as the first choice. However, admission is still subject to the availability of places. Some schools may also have additional qualifying criteria for their affiliated primary school students.
  • For dual-track schools offering both Integrated Programme (IP) and O-Level Programme, affiliation considerations will only be given for the O-Level Programme.
  • At least 20% of the places in each course, i.e. Express, Normal (Academic) or Normal (Technical), will be reserved for students who do not benefit from affiliation priority.

2. Course options

If your child is eligible for only 1 course, they are not allowed to choose another course.

If your child is eligible to choose between 2 courses i.e. between Express and Normal (Academic), or between Normal (Academic) and Normal (Technical), they must choose only 1 course.

As their chosen course will apply to all school choices, your child should apply to schools that offer the selected course.

3. Third Language options

If your child is eligible for a Third Language, list up to 3 choices in order of preference, using the 2-digit language codes.

The Third Language option codes can be found in your child’s Eligibility Letter, as well as on the S1 Internet System.

Important reminder

During the S1 posting process, your child will be posted based on academic merit. This means that a student with a higher PSLE score will be posted to their preferred school before another student with a lower score.

If your child does not get into any of their chosen schools, they will be posted to a school near your registered address that still has vacancies.

For this reason, make sure you:

  • Look at the past year’s PSLE aggregate range for your child’s chosen schools. Note that the aggregate range changes every year, and should only be used as a rough guide. You should include at least 2 choices where the previous year’s aggregate range is at least 5 points below your child’s PSLE aggregate score to increase their chances of being posted to one of their selected schools.
  • Make use of all 6 secondary school options.
  • Update your home address via your child’s primary school by October.
