DSA-Sec applicants who have received either a Confirmed Offer (CO) or are placed on the Wait List (WL) are required to submit their school preferences through the DSA-Sec Portal in mid- to late October. Following this submission, applicants will receive the outcome of their DSA-Sec application through the DSA-Sec Allocation Outcome in late November. If your son accepts a DSA-Sec offer and the DSA-Sec allocation outcome is successful, he will not be allowed to participate in S1 Posting or transfer to another school after the release of his PSLE results.
