Luton and Walderslade are recorded as suburban areas in Medway. Schools in Medway follow the national curriculum for England; tell us your holiday dates and lessons will leave them clear. ### Kent, the South East and our approach More options are on [coding classes in Kent](/coding-classes-in-kent) and [South East England](/coding-and-ai-classes-in-south-east-england). Why every course trains judgement before prompting is on [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Chatham project ## Where should an AI draw the line? ROC curves on Medway's census Score every output area, sweep the cut-off from 1 down to 0, and see what each choice catches and costs. The learner downloads two Census 2021 tables from the Nomis API for all 853 output areas in Medway, covering 111,425 households: the type of each home, and how many cars or vans each household has. An area counts as mostly terraced when at least half its households live in a terraced house, which is true for 296 areas, 34.7% of them. A logistic regression then gives every area a score between 0 and 1 from just two clues: the share of households with no car, and the share with two or more. Every score is produced by a model that did not see that area during training. An ROC curve shows, for every possible cut-off, how many of the true cases are caught against how many false alarms are raised. A useless model runs along the diagonal; a perfect one hugs the top-left corner. The area under the curve, AUC, sums this up in one number: 0.5 is guessing, 1.0 is perfect. Random scores give 0.515, the no-car share on its own 0.642, and the two-feature model 0.673. The clues carry real information, but not much. | Cut-off | Mostly terraced areas caught | False alarms (of 557 other areas) | | --- | --- | --- | | 0.500 | 11 of 296 (3.7%) | 41 | | 0.382 | 51.4% | 161 | | 0.338 | 70.6% | 218 | | 0.308 | 80.1% | 287 | | 0.279 | 90.2% | 356 | The default cut-off of 0.5 is nearly useless here. Because scores rarely rise that high, it catches only 11 of the 296 terraced areas, and its accuracy of 61.8% is worse than simply answering no every time, which scores 65.3%. Lowering the cut-off catches far more, but every extra catch costs false alarms: catching 80.1% means wrongly flagging 287 other areas. Which point is right depends entirely on what a mistake costs. A spam filter and a medical screening test would sit at opposite ends of the same curve. ### Ages 8 to 11 Sort cards by a score, move a line up and down, and count what each position gets right and wrong. ### Ages 11 to 15 Work out catches and false alarms for a few cut-offs in Python and plot them. ### Ages 15 and up Train the classifier, draw the full ROC curve, compute AUC and justify a cut-off by cost. ### ONS counts, our classifier The household counts are Census 2021 figures from the Office for National Statistics, read through Nomis. The labels, the model, the curve and every percentage are our own work; the model says nothing about why housing and car ownership are related. Decisions and AI ## What this teaches about vibe coding and AI agents A score is not a decision until someone chooses the cut-off. | In the Chatham project | In AI tools and agents | | --- | --- | | 0.5 caught 11 of 296 | Default settings can quietly fail | | Always "no" beat the model on accuracy | Accuracy alone hides what matters | | AUC 0.673 from two weak clues | A modest model needs modest claims | | Each extra catch cost false alarms | Every threshold is a trade-off | | The right cut-off depends on costs | Decide what an error costs before tuning | AI-written classifier code almost always ends with a line that turns scores into answers at 0.5, and it rarely mentions that the choice matters. In our vibe coding lessons, where the learner describes what they need and an AI drafts the program, Chatham learners plot the ROC curve and pick the cut-off themselves. AI agents that flag, filter or approve things for you are making the same kind of decision, so knowing who set the threshold, and why, is part of trusting them. Building agents opens up once Python is steady, generally for older teens and adults; Copilot Studio agents are reserved for one-to-one sessions. The [agents pathway for UK students](/ai-agents-course-for-students-uk) shows where this leads, and [understand the code, don't copy-paste](/understand-the-code-dont-copy-paste-uk) explains our approach. Modern Age Coders has no connection with the Office for National Statistics, Nomis or postcodes.io. Their open figures made this project possible; the model and any errors in it belong to us. Stages ## From sorting cards to ROC curves The school year gives us a first estimate; the trial lesson sets the true level. Years 2 to 7 ### How to think Trade-offs, fairness and choosing a line.

[Vibe Coding for Teens](/courses/vibe-coding-for-teens-python-web-ai-projects-course)[AI and Machine Learning for Teens](/courses/ai-ml-masterclass-teens)Adults ### Evaluating AI systems Metrics, thresholds, language models and agents in Python. [Generative AI Course](/courses/complete-generative-ai-masterclass-college)[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)AI and thresholds ## What is an ROC curve, and what does AUC mean? An ROC curve shows every trade-off between catches and false alarms; AUC condenses it into one number from 0.5 (guessing) to 1.0 (perfect). For Medway's mostly-terraced areas the two-feature model scored an AUC of 0.673, and at the default 0.5 cut-off it caught only 11 of 296, less accurate overall than always saying no. Learners who have drawn the curve themselves stop trusting default settings and ask what each kind of mistake would cost. Reading an ROC curve shows Chatham teenagers how AI decisions are actually made, which is a sound reason to take up coding in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## Walderslade to Luton, online Everything happens over video, so a computer and decent broadband are all that is required. ### Learners write the code Students do the typing, prompting and running, while the tutor watches their screen and keeps asking questions. ### The trial sets the level What the learner shows in the free session, rather than the school year, decides where to start; exam boards are noted. ### First lesson free No fee for the opening session, which finishes with a course we recommend. ### Stage-matched groups A class gathers five to ten learners from across Britain who are at one level. ### Two sessions a week Paused during school holidays. ### Steady lesson times Tutors adjust to UK clock changes, so the hour stays the same. Why lessons are online Five learners at one stage, all free on one evening, rarely live near each other. Online, they share a class without the journey. Fees ## Chatham fees Chatham learners pay our international rate, the same in every country apart from India. First class**USD 0** A complete opening lesson free, rounded off with a course suggestion. Group tuition**USD 100** About eight live small-group lessons a month. Private tuition**USD 150** About eight live one-to-one lessons a month. Fees are quoted in US dollars, not pounds, and we bill only after the trial has agreed a course and a weekly time.

FAQ ## Chatham questions ROC curves, the classifier project, vibe coding, agents and fees. ### What is the population of Chatham? The ONS gives 76,955 for the Chatham built-up area at the 2021 census. ### Are AI and programming lessons available for Chatham learners? Yes, through live video for anyone aged 6 to 67 in Chatham and across Medway. ### What does AUC mean in machine learning? The area under the ROC curve: a single number showing how well a model ranks true cases above others, where 0.5 is guessing and 1.0 is perfect. ### What is the Chatham project? Learners train a classifier on Medway's 853 census output areas, draw its ROC curve and choose a cut-off by weighing catches against false alarms. ### Is vibe coding part of the lessons? Yes, at every age, with the learner planning and testing what the AI writes. ### When can learners start building AI agents? After their Python becomes confident, most often in the late teens or adulthood; Copilot Studio agent work is private. ### Are lessons in person? No, all lessons are live online. ### Do you support GCSE and A level? Yes, in computer science and maths, aiming at understanding rather than promised grades. ### How much do lessons cost? Nothing for the opening lesson. Ongoing tuition is USD 100 a month as part of a class or USD 150 a month with your own tutor. ### Do lessons pause for school holidays? Yes. Let us know the dates.
