In short Sentinus Young Innovators 2026 chooses Northern Ireland's Young Scientist, Young Engineer, Young Mathematician and Young Coder of the Year, with an overall Sentinus Young Innovator above them. "Applications must be aged under 19 on July 1st 2027." Scientists submit a poster by 29 September 2026 and engineers by 30 September 2026, while the mathematics and coding categories run "an assessment in late September 2026, to select the finalists"; the first two allow individuals or "teams of up to 3 people" and the second two are individual. The final is "Thursday 26th November 2026" at Ulster University, Belfast, where mathematics finalists face "a 90 minutes live maths challenge" and coders "a 90 minute coding challenge", judged by a panel of industry experts. The overall winner receives a funded trip to the International Science and Engineering Fair 2027 in the USA. We teach the coding and the mathematics. A first class is free; a group place is USD 100 a month and one-to-one teaching USD 150. Where to start ## Three courses for a Sentinus finalist A live challenge rewards what a student can produce unaided, which is a narrower thing than what they know.

A scientist or engineer prepares work at home and brings it; a mathematician or coder sits an assessment to qualify and then performs on the day. They are different competitions wearing one name, and a student should know which one they are entering before September. Above the four titles sits the overall Sentinus Young Innovator, whose prize is a funded trip to the International Science and Engineering Fair in the USA in 2027. The other category winners receive a cash prize, which the organiser publishes in pounds and we do not print. For a school in Northern Ireland this is the nearest thing to a home fixture on our whole [competitions calendar](/uk-coding-maths-and-ai-competitions-calendar). Almost everything else on it is run from England and sat at a desk; this one ends with a day at Ulster University and a panel who work in the field. It also runs early. The assessment is in late September and the final in November, so a student thinking about it in October has already missed the first stage. That is worth knowing in the summer term, not the autumn. Source: [Sentinus Young Innovators](http://www.sentinus.co.uk/programmes/sentinus-young-innovators/), read 20 September 2026. Modern Age Coders is not connected with Sentinus or Ulster University. The method ## The age rule is a Northern Ireland school-year rule Sentinus sets eligibility by birthday rather than by year group. In Northern Ireland, and only there, those two things come to almost exactly the same thing. The rule is "aged under 19 on July 1st 2027". Turn that into a birth date and something interesting appears. | Step | Result | | --- | --- | | "Under 19 on 1 July 2027" means born after | 1 July 2008 | | Northern Ireland's compulsory school age cut-off | 2 July | | So a Northern Ireland school year runs from | 2 July to 1 July | | A pupil born 30 June 2008 is | Too old, and a school year above | | A pupil born 2 July 2008 is | Eligible, and in the year below | ### Why this is unusual An age rule normally cuts across a year group, so a class contains some eligible pupils and some not. Here the rule falls on the school-year boundary itself, so whole year groups are in or out together. ### Why only in NI England uses 1 September. The same "under 19 on 1 July" rule applied to an English school would split a year group roughly in half, which is exactly the confusion this avoids in Belfast. ### What a teacher can do with it Check one pupil's birthday and you know about the whole class. That is worth thirty separate checks in a busy September. None of this is an accident of luck; it is what happens when a Northern Ireland organisation writes a rule for Northern Ireland schools. It is also the kind of detail that gets lost when a UK-wide site copies an eligibility line without asking which school system it was written for. It matters practically because sixth form in Northern Ireland runs to Year 14 rather than Year 13, and students assume an under-19 rule excludes them. Often it does not. The wider lesson, for anyone who writes rules, is that a date is never just a date: it belongs to a system. Our [UK page](/coding-classes-in-united-kingdom) works through the four different school-start rules in Britain and what one birthday does under each of them. The Northern Ireland cut-off we use here was read at the Department of Education for that page on 19 September 2026, and our own first draft of the rule was a year out, which is recorded there too. The arithmetic is ours, computed on 20 September 2026 from the organiser's published eligibility rule and the Northern Ireland compulsory school age cut-off. The final ## Ninety minutes, live, with nothing brought in A live final is not a harder version of a take-home task. It tests a different thing, and it can be practised. | Rewarded | Why | Not rewarded | | --- | --- | --- | | Writing code from memory | There is no time to look up how a thing is spelled | Knowing where to find an answer | | Choosing a method quickly | Ninety minutes is enough for one good plan and not two | Exploring three approaches | | Starting with something that runs | A partial working program beats an unfinished elegant one | Designing before typing anything | | Reading the whole task first | Late requirements change early decisions | Starting at the first sentence | | Calm under observation | A panel is watching, and that is a skill of its own | Anything practised only alone and untimed | The single most useful practice is the least fashionable: sit down with a clock, no internet, and a problem you have not seen, for ninety minutes, once a week. Everything else follows from finding out what you actually reach for when nothing can be looked up. The second is to get something running in the first fifteen minutes, even if it only handles the simplest case. A student with a working partial answer at minute eighty is in a far better position than one with an ambitious half-finished design. For the mathematics final the shape is the same: ninety live minutes, unfamiliar problems, no reference. The [olympiad pages](/british-mathematical-olympiad-bmo-preparation) on this site are about exactly that kind of work. And whether or not a student reaches Belfast, practising under a clock without a search engine is the rarest and most useful habit we teach. Most young programmers have never once worked without one. Getting ready ## Four rungs to a live final Each rung is something a student can do without help, which is the only thing a live challenge can see. | Stage | Rung | The sign it is secure | | --- | --- | --- | | Years 8 to 10 | 1. Fluent basics | Writes input, loops and conditions without looking anything up | | Years 10 to 11 | 2. Unaided debugging | Finds and fixes an error without asking or searching | | Years 11 to 13 | 3. Under a clock | Produces a working partial answer inside the first quarter of the time | | Years 12 to 14 | 4. Under observation | Does all of the above with somebody watching | ### If September is close The assessment that selects finalists is in late September, so an entry has to be decided in the summer term rather than the autumn. Practise one ninety-minute sitting a week with no internet. Nothing else prepares for a live final. ### Whatever happens in November Working without a search engine is a skill almost no young programmer has, and it is the one employers notice first. The rest of the season is on the [competitions calendar](/uk-coding-maths-and-ai-competitions-calendar), including several open across all four nations.

Weekday evening The usual slot for Years 11 to 14. Weekend morning Long enough for a full ninety-minute sitting. September weeks For the run-up to the selection assessment. ### Timed sittings We run ninety-minute practices with nothing to look up, because that is the round. ### Unaided debugging A student finds their own error while a teacher watches and says nothing, which is uncomfortable and works. ### Five to ten students Enough for two approaches to meet, small enough for every program to be read. ### Northern Ireland years used Year 12 and Year 14 mean what they mean in Belfast, not what they mean in Birmingham. ### One to one when useful For a finalist in the weeks before November. ### No role in the competition We do not enter students, and we have no relationship with Sentinus.

Ritu Kedia Parent Sentinus Young Innovators questions ## What Northern Ireland families ask ### What is Sentinus Young Innovators? Northern Ireland's STEM competition, choosing a Young Scientist, Young Engineer, Young Mathematician and Young Coder of the Year, with an overall Sentinus Young Innovator above them. ### Who can enter? The organiser says applications must be aged under 19 on 1 July 2027. That works out as born after 1 July 2008. ### Does the age rule match school years? In Northern Ireland, almost exactly. The compulsory school age cut-off there is 2 July, so an NI school year runs 2 July to 1 July and the eligibility window falls on the boundary. A pupil born 30 June 2008 is too old and one born 2 July 2008 is eligible, and they are a school year apart. ### How does a coder qualify for the final? Through an assessment in late September 2026 that selects the finalists. Scientists and engineers instead submit a poster, by 29 and 30 September 2026 respectively. ### Can students enter as a team? In the scientist and engineer categories, yes: individuals or teams of up to three people. The mathematics and coding categories are individual. ### What happens at the final? It is on Thursday 26 November 2026 at Ulster University, Belfast. Mathematics finalists face a 90-minute live maths challenge and coders a 90-minute coding challenge, judged by a panel of industry experts. ### What does the winner get? The overall Sentinus Young Innovator receives a funded trip to the International Science and Engineering Fair 2027 in the USA. Category winners receive a cash prize, which the organiser publishes in pounds and we do not print. ### How should a student prepare for a live coding round? By sitting ninety minutes a week with a clock and no internet, and by aiming to have something running in the first fifteen minutes. A working partial answer beats an unfinished elegant one. ### Is it only for Northern Ireland students? Sentinus is a Northern Ireland organisation and the competition and its final are run there. Check the organiser for anything outside that. ### Do you enter students or coach them for the final? We teach coding and mathematics in live online classes, including timed practice. We do not enter anyone and have no relationship with Sentinus.
