The content in the beta is accurate and up to date. Feel free to give us your feedback which will help us to improve it!

Parents who intend to use the P1-IS in Phase 2C / 2C Supplementary are required to set up their SingPass 2-Step Verification (2FA). Parents are advised to set up their SingPass 2FA early if they have not done so.

For more information on the 2FA setup, please visit the SingPass website.

Parents who wish to familiarise themselves with the details of online registration can refer to the P1-IS Guide

P1 registration is not first-come, first-served. There is no special priority given to early applicants, whether through online or school registration.


The Primary One Internet System (P1-IS) serves as a channel to facilitate the registration of children during Phase 2C and Phase 2C Supplementary.  

Online Registration via P1-IS

Parents may register online if,

  • your child is eligible for registration in Phase 2C or 2C Supplementary
  • your child’s birth is registered in Singapore and the child holds a Singapore-issued Birth Certificate
  • both parents have valid SingPass with 2FA setup
  • both parents are Singapore Citizens or Singapore Permanent Residents at the time of your child’s birth

In addition, single parents may register online via the P1-IS if (i) only that parent’s particulars are reflected in the child’s Birth Certificate, or (ii) one parent is deceased.

The P1-IS is accessible 24 hours during the following periods:

  • Phase 2C

    Starting from 29 July 2019, 9.00am to 31 July 2019, 4.30pm.

  • Phase 2C Supplementary

    Starting from 12 August 2019, 9.00am to 13 August 2019, 4.30pm.

Please refer to Frequently Asked Questions for more information on P1-IS.

The address reflected in the P1-IS is the official residential address on both parents’ NRIC as at 31 May 2019. If the address in the P1-IS is different from that currently on your NRIC, please approach your school of choice with the required documents to register your child.
