The Southeast Asian Coding and Software Olympiad (SEACSO) is an annual coding competition organized by GLOW Inc. with six grade categories across Southeast Asia. Its introduction says grades 1–12, while the detailed Category I and mock-test sections include kindergarten; the source wording is left explicit. The competition uses the Codementum platform and is structured into six grade-level categories.

| Category III | Grades 5–6 |
| Category IV | Grades 7–8 |
| Category V | Grades 9–10 |
| Category VI | Grades 11–12 |
What participants do:
- Write and run code using Blocks, Python, or JavaScript through the Codementum Portal
- Complete web design challenges using HTML, CSS, and JavaScript (some categories)

Calendar checked November 4, 2026: The organizer homepage links its 2026–27 calendar. The SEACSO row lists registration beginning June 2026, without an exact day; no exact opening is inferred. It separately labels competition dates: Worldwide round: 2027-01-16. These are qualifying/national test dates (the image specifically labels January 16 worldwide), not universal country registration/payment deadlines. Local entry cutoffs and cutoff clocks/timezones were not verified.
Its international event is 2027-04-08 to 2027-04-12, venue Yogyakarta, Indonesia. An older March 17, 2026 organizer letter hosted by DepEd listed March 19–22, 2027 in Indonesia, differing from the current homepage calendar’s April 8–12 Yogyakarta dates. The current organizer image is used for the listed event, with that older schedule disclosed. Registration, payment and detailed exam/arrival timing for this event remain unverified.
The official 2026 event post supports the historical 2026-03-05 to 2026-03-09 event in Tagaytay City, Philippines; its local check-in arrangements are not upcoming entry deadlines. National tests and the international event are separate stages, with the published higher-60% qualification rule. Current fees and aid coverage were not established by the checked official calendar and guides.
The current calendar labels SEACSO “Southeast Asia Computer Science Olympiad.” The programme page’s grade 1–12 introduction differs from detailed Category I/mock-test sections that include kindergarten. No universal kindergarten eligibility decision is inferred from that wording difference.
