需在登记注册的地址住满30个月。那些在注册时租学区房的想法不太可行了，除非在租住地阻满30个月。
The address used in the P1 Registration Exercise should be the parents’ official residential address as reflected on their NRICs. This address will be used to determine the home-school distance category, where required for consideration of priority in admissions.
The home-school distance category priority is given with the expectation that the family will reside at the address for the duration of the child’s primary school studies, as it is for the convenience and interest of the child.
In a small number of cases, there may be situations where the families are unable to remain at the address used for registration for the entire duration of the child’s primary school studies. Even so, a child who gains priority admission into a school through his/her distance category is required to reside at the address used for registration for at least 30 months from the commencement of the P1 registration exercise on 2 July 2015. If this condition is not met, MOE reserves the right to transfer the child to another school with vacancies, as the priority admission to the first school was based on the declared address used for registration.
