Aided or government primary and secondary schools implementing the "through-train" mode should have the same philosophy and aspiration for education and strive to enhance continuity in primary and secondary education. There should be enough S1 places in the "through-train" secondary school to admit all P6 graduates of the linked primary school. Some S1 places are also reserved so that P6 pupils of other primary schools could have a chance to be admitted through the discretionary places or central allocation process. A P6 pupil of a "through-train" school may proceed to its linked secondary school direct without going through the central allocation process. If he/she chooses not to enter the linked secondary school, he/she may apply for a discretionary place of another secondary school. If he/she decides to apply for a discretionary place of another secondary school but his/her application is rejected, he/she can only participate in the central allocation process and will not be allowed to retain the right to an S1 place in the linked secondary school. With regard to the "through-train" arrangements implemented in Direct Subsidy Scheme or private schools, parents should contact the schools direct.
