SCO Olympiad 2026–27: key dates at a glance

What to check	Published information	What it means
Cycle shown on live exam calendar	WINTER 2027	A cycle label, not the calendar year of the next exam

Upcoming listed dates after 21 October 2026	6, 14, 15 November 2026; 4, 12, 20 December 2026	Six future published schedule dates, not six confirmed live seats
Already past calendar date	18 October 2026	Do not present it as the next date after 21 October

Last reviewed: 21 October 2026. The public calendar lists the 2026 examination dates for a cycle called Winter 2027. The separate results calendar calls the corresponding August–December 2026 result window 2026 WINTER and labels its results date 28 February 2027. These are different displayed naming conventions; always quote the actual exam date and the result publication window rather than guessing from a cycle title. The date listed does not establish open registration in every country or class.

The current published SCO Winter 2027 exam dates

The official SCO online date page displays the following six examination days later than 21 October 2026. Check the live page again before planning or submitting a form, because organisers can change cycles or available subjects.

Month	Date (day–month–year)	Status as of 21 Oct 2026
November	6 November 2026	Future published date
November	14 November 2026	Future published date
November	15 November 2026	Future published date
December	4 December 2026	Future published date
December	12 December 2026	Future published date
December	20 December 2026	Future published date

The same cycle includes 4, 12 and 20 September; 2, 10 and 18 October 2026 on the full public list, but these six dates are past. Some shorter public displays begin at 18 October. Do not treat a date as upcoming just because it remains visible in an archived calendar or in a search-engine snippet.

Does a scheduled date mean I can book a seat?

No. A schedule page is not a real-time booking confirmation. The actual student registration process must accept the subject, class, country and date, show any applicable charges and issue a valid confirmation. A parent should keep the receipt and examination instructions only after that step. Do not make travel arrangements based only on a public date card.

Subject and class eligibility in the active exam calendar

The live cycle-by-cycle public timetable shows these classes for named subjects; other cards say class-wise options. That wording is important. The wider subject directory may advertise Grade 1–12 learning while the active examination offers a narrower range.

SCO subject	Abbreviation	Class information shown on current cycle page
Artificial Intelligence	IAIO	Classes 6–12
Biology	IBO	Class-wise options; verify actual booking eligibility
Chemistry	IChO	Class-wise options; verify actual booking eligibility
Coding	ICO	Classes 6–12
English	IEO	Classes 1–12
Entrepreneurship & Innovation	IEIO	Class-wise options
Finance Knowledge	IFKO	Class-wise options
General Knowledge	IGKO	Classes 1–10
Life Skills and SDGs	ILSO	Class-wise options
Mathematics	IMO	Classes 1–12
Mental Ability	IMAO	Class-wise options
Physics	IPhO	Class-wise options
Science	ISO	Classes 1–12

The broader SCO subject directory describes additional learning subjects and grade coverage, but it is not evidence that every grade has an exam date in the active cycle. In particular, a Grade 4 pupil can explore age-appropriate AI or coding learning, yet the Winter 2027-listed IAIO and ICO exam cards currently show Classes 6–12. Do not promise a Grade 4 examination slot based on a general subject description.

What do Spring, Summer and Winter cycles mean?

SCO has used Spring, Summer and Winter as cycle names. The current date page presently shows one active cycle with published dates: Winter 2027. The separate SCO results calendar shows reporting windows and result dates for other cycles. A planned result window is not the same as a published schedule of actual exam bookings.

Result-calendar cycle	Window shown by SCO	Result date shown	Meaning for students
2026 Winter	1 August–31 December 2026	28 February 2027	Current reporting calendar; active public exam page calls its date cycle Winter 2027
2027 Spring	1 January–31 March 2027	30 April 2027	Result-calendar planning information; do not infer actual exam-day slots
2027 Summer	1 April–31 July 2027	31 August 2027	Result-calendar planning information; do not infer actual exam-day slots
2027 Winter	1 August–31 December 2027	29 February 2028	Future results-cycle row, not currently verified exam availability

Source: the SCO cycle results calendar. The 2028 February date is a valid leap-year date. Do not interpret these result-planning ranges as fixed international finals, guaranteed release to every student on the stated day, or independently bookable national/regional rounds.

Step-by-step: choosing a date and registering as an individual

Start with the subject: visit the official subject directory and choose Maths, Science, English or another relevant subject.
Check your class: use the active date card for its class range. Do not treat Grade 1–12 promotional text as proof of a Grade 1 exam in every subject.
Compare actual future dates: check the displayed day, month and year; for October 2026 the visible 18 October date is already past.
Open the real registration form: use official student registration, choose the exact subject and confirm what date the system actually offers.
Review fees and payment: the public form shows prices in INR and USD. Before paying, confirm your checkout currency and any exchange or card fees.
Check exam time and language: verify the full time zone and paper language from official instructions for the selected examination. International visitors should not assume English/local-language support or a fixed UTC offset.
Keep confirmation private: save the successful booking details, receipt and access instructions. A public schedule screenshot alone is not proof of an appointment.

For schools: cycle planning and requests for a custom date

The official School/Institution Registration page provides a separate planning form for school coordinators. It asks for institution details, country/region, time zone, coordinator contact, preferred subjects and class ranges. The form allows selection of a published date or a custom date request for review. A requested custom date is not automatically approved. Schools should await explicit acceptance and onboarding instructions.

Confirm the name and country of your school, and designate the coordinator responsible for exam communication.
Prepare approximate pupil numbers by class and subject; avoid collecting more personal data than needed for the approved school workflow.
Choose a cycle and review subject-specific published dates against term exams, local holidays and school events.
If the published date conflicts with the school calendar, use the school’s custom-date request pathway and retain written approval before notifying families.
Follow the provider’s subsequent onboarding process for student uploads, payments, training and examination access; do not assume that submitting the initial form creates confirmed examinations.

Frequently asked questions: SCO exam dates 2026–27

What is the next published SCO Olympiad date after 21 October 2026?

The current public Winter 2027-labelled schedule next lists 6 November 2026. That is a published date, not a guarantee that every class or country can book it.

Why is the cycle called Winter 2027 when the exam dates are in 2026?

That is the label used on the public exam-date page; it shows actual examination dates in September–December 2026. Always use the full date and the cycle separately.

Are 14 and 15 November 2026 published exam dates?

Yes. They appear after 6 November, followed by 4, 12 and 20 December 2026 on the public current-cycle schedule.

Is 18 October 2026 still an upcoming exam?

No. On this article’s 21 October 2026 review date, 18 October had passed even though it remained visible in older date listings.

Do all SCO subjects admit students in Classes 1–12?

No. The current public cards list Maths, Science and English for Classes 1–12, AI and Coding for Classes 6–12, GK for Classes 1–10, and class-wise conditions for other subjects.

Can a Class 4 student participate in the current SCO AI exam?

The active date card says IAIO Classes 6–12. Free beginner AI learning may suit a younger child, but do not promise a Class 4 Winter exam booking.

Can a Class 5 student book the Coding Olympiad on these dates?

The live Winter 2027-labelled ICO card shows Classes 6–12. Confirm the current class range before any payment.

Which subjects are shown as active on the Winter 2027 public timetable?

The page lists 13: AI, Biology, Chemistry, Coding, English, Entrepreneurship & Innovation, Finance Knowledge, General Knowledge, Life Skills, Maths, Mental Ability, Physics and Science.

Does the broader SCO directory mention subjects not shown in the date calendar?

Yes. General subject information may have broader entries than the currently published 13-subject cycle. A directory listing alone does not establish an active exam date.

Can I register for the September 2026 dates now?

Those dates are past as of 21 October 2026. Use the official live schedule for upcoming options and the actual booking form to verify availability.

Are registration fees the same for every subject?

Not necessarily. The official student form shows subject-wise fees and INR/USD options; review the price for the selected exam and your actual checkout.

Are SCO exam times always the same in every country?

Do not assume this. Confirm the organiser’s actual start time and time-zone designation, then convert for the student’s local time.

Do schools have to use the individual student form?

SCO has a separate School/Institution Registration process for planning multiple pupils, classes and subjects. Use the route appropriate to your situation.

Can a school ask for another examination date?

The school form offers a custom-date request pathway for review. A requested date is not confirmed until the organiser approves it.

When are 2026 Winter SCO results scheduled?

The SCO results calendar displays a cycle result date of 28 February 2027 for its 1 August–31 December 2026 Winter reporting window. Actual publication of a specific result should be checked in the result portal.

Does the result date mean certificates are guaranteed on that day?

No. Results, rankings and certificates depend on the authorised release and participant record. Use the official SCO result portal for a confirmed publication.

Are Spring and Summer 2027 examination days already confirmed?

The result-calendar page shows reporting windows and planned result dates. At the 21 October 2026 review, the public exam-date page showed only the active Winter 2027-labelled exam cycle; do not infer specific future exam-day slots.

Do all SCO subjects automatically have a national and international qualifying round?

The current public date page does not independently confirm universal two-level qualification. Check the specific current subject and level rules before telling pupils they must qualify for another round.

Can I use School Connect free lessons without registering for a paid exam?

Yes. SCO provides free chapter-wise learning, linked educational videos and practice questions. Students do not need any retired Learn, Grow or Compete subscription package.

Where can I verify the current registration and result?

Check the official exam-date listing, open the actual student or school registration process and consult the official SCO results portal for released outcomes.
