What are the best coding classes in County Cavan?
Cavan is a young county by Irish standards. Its 81,704 people have an average age of 38.5, below the national 38.8, and 17,752 of them are aged 15 or under. Cavan town holds 11,741, then a run of similar-sized towns: Virginia 3,211, Bailieborough, Kingscourt and Ballyjamesduff each just under 3,000. Two Cavan schools were among the first forty to teach Leaving Certificate Computer Science. For our classes the first lesson is on us; a group place after that is USD 100 monthly and one to one USD 150, taught live each week to anyone aged six to sixty-seven.
Here is a mistake that produces no error message and hands county after county the wrong population. The statistics office publishes its county table with Cavan third, after Cork City Council and Clare, and before Cork County Council, Carlow and Dublin City. That is neither alphabetical nor anything else obvious. It is simply the order the rows were stored in. Sort a list of county names alphabetically, line it up against those values by position, and Carlow gets Cork City's figure, Cavan gets Clare's, and so on down the list. Every number is real, every name is real, and the pairings are wrong. The same table also says it was updated in June 2023, for a count taken on a night in April 2022. Neither trap is exotic. Both are everywhere.
Facts last verified 16 September 2026. Teaching is online; no County Cavan branch is claimed.
Choose by age and appetite; the first lesson confirms the choice. It is taught by the teacher who would take the course, and nobody asks for card details to book it.

See the syllabusCavan County Council publishes no open datasets, so the project uses the national county population table and two things about it that fool careful people.
| Position | Stored order | Alphabetical order |
|---|---|---|
| 1 | Cork City Council | Carlow County Council |
| 2 | Clare County Council | Cavan County Council |
| 3 | Cavan County Council | Clare County Council |
| 4 | Cork County Council | Cork City Council |
| 5 | Carlow County Council | Cork County Council |
| 6 | Dublin City Council | Donegal County Council |
Pair the two columns by row number and not one county in those six lines gets its own figure. The script runs, the chart draws and every bar carries a real county name above a real population belonging to somewhere else.
Check one pair you already know. Cavan's population is 81,704. If the row labelled Cavan says anything else, the join is broken, and it takes ten seconds to find out.
Never match by position. Match by the code or name stored alongside each value, which the table provides for exactly this reason.
The table's own metadata gives an update date of 29 June 2023. The figures inside it describe the population on 3 April 2022, census night, fourteen months before. Anyone reading that timestamp as the date the numbers describe will think the data is more recent than it is. Nearly every published dataset has at least two dates attached to it, when the thing was measured and when the file was last touched, and they are routinely confused in reports, dashboards and news stories. A learner who asks which date a figure is actually as of has avoided an error most adults make without noticing.
The written output is two short paragraphs. One explains why joining by position is unsafe and shows the one-pair check that exposes it. The other states, for every figure used in the project, the date it describes rather than the date the file changed. That second habit is worth a great deal more than it looks, because it is the difference between reporting how things were and implying how things are.

| What was counted | Result |
|---|---|
| Residents | 81,704, up 5,528 or 7% since 2016 |
| Female and male | 40,644 and 41,060, or 101 males per 100 females |
| Average age | 38.5, up from 37.2 and still below the national 38.8 |
| Aged 15 and under | 17,752, with 6,104 of them in childcare |
| Non-Irish citizens | 12% of the county, led by Polish at 1,719, UK at 1,564 and Lithuanian at 1,398 |
| Holding dual Irish citizenship | 2,335, up from 1,297 |
11,741 people over 12.4 square kilometres, an average age of 35.8 and 24.3% under 15, a young town inside a young county.
Virginia 3,211, Bailieborough 2,974, Kingscourt 2,955, Ballyjamesduff 2,917, Cootehill 1,856, Mullagh 1,651 and Belturbet 1,610, which squeezes its population into a single square kilometre.
Among places of at least 500 people, Mullagh has the youngest average age at 34.1 and Cootehill the oldest at 40.4.
Irish is spoken by 26,591 of the 78,633 people aged three and over, 35.9%, up slightly on 2016, and Cavan has no Gaeltacht area. We teach in English and programming keywords are English in every language, so nothing on that front affects a learner here. The county's religious make-up has also shifted quickly: the Catholic share fell from 82% to 74% between the two censuses and the number stating no religion rose by 77% to almost 6,900.
Cavan is one of the counties that had computer science in the Leaving Certificate from the very start.
Published on the January 2018 list at Cootehill Road, Cavan. The road is named for Cootehill but the school is in Cavan town, which is worth knowing before anybody files it under the wrong place.
In Cootehill itself, and the county's second school among the forty that began the subject in September 2018 and sat the first exam in 2020.
The statistics office reports that Cootehill had the second highest rate in the country of primary pupils travelling to school by public transport, at 31%.
| Mode or measure | People or time |
|---|---|
| Travelling to work | 32,111 |
| By car | 21,127 |
| On foot | 2,075, up from 1,834 |
| By bicycle | 169, with Cavan and Donegal commuters the least likely in the country to cycle, at 0.5% |
| Average journey | 30.7 minutes, up from 28.5 in 2016 |
| Working from home at least one day a week | 7,898 people, 22% of the workforce against 32% nationally |
Where the first-wave schools leave everyone else
Two schools with the subject from the start is a real advantage for pupils at those two schools. For a teenager in Kingscourt, Belturbet or Virginia it changes very little, and with the average commute already past half an hour, a weekly evening trip into Cavan town for a class is a hard sell. Third level attainment here is 38% against 45% nationally, and the average age of finishing full time education, 19.8, is a year below the national figure, so the case for an accessible way to go further is strong.
Both read on the organisation's own website.
Virginia Road, Ballyjamesduff, eircode A82 YP70. It holds the Killycluggin Stone and a First World War trench that the museum describes as the largest outdoor replica trench open to the public in Ireland and the UK.
Cavan Courthouse, Farnham Street, Abbeyland, Cavan, eircode H12 R6V2, a different routing key from the museum in the same county.
Its publisher page on the national portal lists no datasets at all, which is why the project above works from national statistics instead.
This page covers the Republic of Ireland only. Cavan borders Northern Ireland, but the statistics office's Cavan employment and commuting release says nothing about travel across the border, so we publish no figure for it and use no Northern Ireland statistic anywhere. Nor are we connected with Cavan County Council, the museum or either school. Population and travel figures are the statistics office's, and the stored order and update date described in the project were read directly from its published table.

Ask for two lists to be combined and a tool will often pair them by position, because that is the literal meaning of the request and it works on every tidy example it has seen. On the county table it produces a clean, plausible, entirely wrong result, and nothing in the output hints at it, since every name and every number is individually genuine.
The protection is not a better prompt. It is the ten-second habit of checking one pair you already know. Cavan is 81,704; if the row labelled Cavan says otherwise, stop. People who have been caught once by a positional join do that forever, and they are the people you want checking anything important.
That is why the case for learning to program properly has, if anything, grown: somebody still has to know what a correct answer looks like. The longer argument is in the case for learning to code in 2026.
The practical shape of the teaching.
Every lesson is taught as it happens, with questions both ways, rather than watched as a video.
Five to ten learners at one ability level, gathered from Cavan and other countries, so nobody is waiting for the room to catch up.
Two lessons most weeks, about eight a month, at a slot agreed once and kept.
Junior Cycle through Leaving Certificate, with exam seasons and holidays planned around rather than ignored.
A computer, sound that works and a connection able to carry video. The first lesson doubles as a test of all three.
Where no group at the right level meets at a workable time, the same course is taught one to one.
For the lake country and the border villages
Much of Cavan lives outside its towns, among lakes and small roads where a thirty minute drive is normal and a bus to an evening class is not. Gathering learners at the right level into one online group, at an hour fixed once for the whole term, reaches families that no class in a hall in Cavan town could.
Three figures, with nothing further to find.
A first lesson in full at no charge, which ends with a level and a recommendation.
Group lessons for a month, around eight of them, with five to ten learners at one level.
One to one lessons for a month on the same schedule.
Monthly billing is in US dollars at the single rate we set for families outside India, so Cootehill and Cavan town pay the same and there is no euro price to compare it with. No payment is taken before a course and a time are agreed in that first lesson, and the pricing page spells out pauses, missed lessons and changing between group and private.

Let us know the learner's age and interests. The opening hour is planned around them, from a Scratch game about keeping two lists in step to the county table that pairs every name with the wrong number.
What Cavan families tend to ask first.
The 2022 census counted 81,704, up 5,528 or 7% since 2016, with an average age of 38.5, slightly younger than the country as a whole.
Two of the first forty: Breifne College on Cootehill Road in Cavan town, and St Aidan's Comprehensive School in Cootehill.
Learners discover that the national county table stores Cavan third, not in alphabetical order, so pairing values by position mislabels the counties, and that its update date is fourteen months later than the census night its figures describe.
It held 11,741 people in 2022, with an average age of 35.8 and nearly a quarter of residents under 15.
No. Everything here is from Republic of Ireland sources, and the statistics office's Cavan commuting release contains no cross-border figure, so none is given.
Yes. Virginia, Bailieborough, Kingscourt, Ballyjamesduff, Cootehill and Belturbet all get exactly the same teacher at exactly the same hour.
After school, evenings and weekend mornings. Our teaching staff are in India, which is four and a half hours ahead of Ireland in summer and five and a half in winter; the slot is fixed in the first lesson.
No, and we never imply one. Teaching is live over video only, with no premises in Ireland. A learner needs a laptop or desktop, working sound and a steady connection, and the number shown here belongs to India.
The first lesson is free. After that a shared place costs USD 100 a month and brings two live lessons a week, about eight monthly, with five to ten learners; one to one on the same schedule is USD 150 a month. Everything is agreed before payment.
Five to ten, grouped by ability, pace and goal rather than age or address. Where nothing suitable meets at a workable hour, we teach one to one instead.
