Explaining Models to Non-Experts
Explain what a model does, how well it works and how it should — and should not — be used, in plain language.
In this lesson you will
- Explain predictions and performance in plain language
- State limits and the role of human judgement

The lesson
Decision-makers need to know what the model predicts, how often it is right in terms they understand ('it finds about 8 in 10 students who later drop out, with about 1 false alarm for every 3 alerts'), and what to do with its output.
Show which features matter most, but do not overstate them as causes. Use examples of individual predictions to make the model concrete.
Be explicit about limits: the data it was trained on, groups where it performs worse and the need for a person to review every flagged case. A model should support decisions, not make them alone.
Step by step
- Translate recall and precision into a sentence about students.
- Show the three most important features with a caution.
- Write a 'how to use this model' section.
- Write a 'limits and risks' section.
Practice activity
Write the one-page plain-language summary for the level project.
Expected result: A summary a head teacher could act on, with honest limits and a clear role for human judgement.
Check your understanding
-
How should feature importance be described to non-experts?
Show answer
As association in the data, not as proven causes.
-
Why keep a person in the loop?
Show answer
Models make mistakes and miss context; people must review decisions that affect others.
