SJPed is an open-access journal. There is no submission fee. An Article Processing Charge (APC) is levied only after a manuscript has been accepted for publication following peer review. The APC supports editorial processing, copyediting, layout, DOI registration, and long-term digital preservation. Editorial decisions are based solely on academic merit, ethical compliance, peer-review results, and journal suitability, and are never influenced by an author's ability to pay.

• Authors not from Tier A or ASEAN countries: the standard APC of USD 225 applies.

Mixed-country authorship

For manuscripts with authors from more than one country, the applicable tier is determined by the country of the corresponding author's institutional affiliation at submission. Where there is more than one corresponding author, the tier follows the primary corresponding author named in the submission e-mail.

Payment and conditional acceptance

After peer review and acceptance, the journal issues a Conditional Acceptance Notification together with the APC invoice. The official Letter of Acceptance (LoA) is issued only after the APC payment has been completed and confirmed. Authors must complete payment within three (3) calendar days of the invoice date. If payment is not completed within this period and no prior written agreement has been approved, the manuscript may be considered withdrawn for non-payment, and the journal reserves the right to discontinue further processing. Repeated failure to pay after conditional acceptance without valid justification may be recorded for internal administrative purposes, and future submissions from the same corresponding author may require confirmation of payment before any formal acceptance document is issued.
