Pilots for schools and colleges

Learn to read code, not just write it.

AI can write code for you. Decoded teaches you to understand it, and to use AI well. Real HTML, CSS and JavaScript, one small piece at a time.

The problem

AI writes the software. Who understands it?

AI now writes working software for anyone who asks. Very few people can tell what it built, whether it is safe, or how to change it.

What did it build?

A tool that works is not the same as a tool that is understood. Reading the code shows what it actually does.

Is it safe?

Problems hide in code. Someone who can read it can spot what looks wrong and knows when to ask for help.

How do I change it?

Changing a tool starts with knowing where to look. Understanding the code means you are not waiting on whoever made it.

How it works

One small piece at a time

  1. Step 1

    Pick a lesson

    Lessons are short and sit in tracks, starting with HTML and CSS.

    Pick a lesson from a track.

  2. Step 2

    Understand it

    Each lesson ends with quick questions, and every wrong answer comes with its own explanation, because the misunderstanding behind a wrong answer is where the teaching happens.

  3. Step 3

    See progress

    Learners earn points and levels as they go, with a daily streak.

One idea, two halves

  • Understand code

    Including the code that AI has written for you.

  • Use AI well

    Courses on using AI effectively.

  • Practise writing code

    A place to try what you have learned.

  • Optional leaderboard

    Off by default, with generated names only.

Who it helps

Two audiences, one skill

Built safe for young people

Why Wales

Why we are doing this for Wales

Wales produces less per hour worked than any other part of the UK, and GVA per head is the second lowest. Almost half of Welsh businesses do not use AI, and the reasons they give are skills, cost and not knowing where to start.

Where schools and colleges come in

Skills are the part we can do something about

  1. The barrier

    Expertise and knowing where to start

    Two of the three barriers businesses gave, expertise and difficulty identifying use cases, are skills.

  2. The lever

    Teach it early, in school and college

    Skills can be taught. Schools and colleges are where young people can learn to read the code AI writes and to use AI well.

  3. The aim

    People who can judge what AI builds

    Learners who leave able to question what AI produces, and who know where AI could help.

Our aim is free access for learners in Wales, supported by paid pilots and partnerships with schools, colleges and larger organisations.

Pilots

Bring Decoded to your students

The first course is live. Pilots are paid for by the school or college, priced to be very affordable, and every student in the pilot gets free access. We are shaping the offer with our first partners, so tell us what would work for you.
