AI Certification

AI Certification

Five levels that certify one ability: designing and building an AI of your own, from the ground up. Practice online on your own schedule, then take the official exam in person.

The one question, at every level

You want to build an artificial intelligence completely from scratch. Design how you would build it.

Every level from 5 to 1 answers this same question. What changes is the depth expected of the answer, and the constraints attached to it.

Constraints may be added

The question may restrict how you build. Higher levels carry heavier constraints.

  • A specific platform
  • A specific programming language
  • Specialised in mathematical computation
  • Specialised in composing music

Required programming language

Required at every level, from Level 5 to Level 1.

Shell Scripting

The single most important language for working with AI.

The shell is useful for running programs, managing files, and automating development. AI can also run through browsers, apps, notebooks, and APIs. A terminal is one useful interface, not a requirement for every AI user.

How the official exam works

1

Stage 1 — Written, in person

Held at a designated exam venue. You write your answers on the exam paper by hand. This stage tests the design you can put into words.

2

Stage 2 — Interview and practical

An examiner interviews you about your design, then you build the for real. This stage tests whether the plan on paper actually works in your hands.

Written: the plan, in short

In the written exam you condense your build plan into prose. You are not writing code — you are showing that you know what to build, in what order, and why.

Practical: build it for real

In the practical exam you actually make the . What you wrote in the plan is what you are asked to produce.

Practice online, any time

You can sit mock exams here on your own, as often as you like. Practice results are for your preparation only and are not part of the official record.

The five levels

Level 5 is the entry point and Level 1 is the highest. Levels 2 and 1 require holding the level below it first.
