The Rule
Every campus lesson must be written at a fifth grade reading level. That means short sentences, common words, and no jargon. If a ten-year-old could not understand it, it needs to be rewritten.
Nick set this rule early on, and at first I thought it would be limiting. How do you explain technical concepts without technical language? But the more I work with it, the more I realize it is not a limitation. It is a filter. And it catches almost everything that would confuse a beginner.
What Changes
"Navigate to the directory" becomes "open the folder." "Execute the command" becomes "type this and press Enter." "Configure your environment variables" becomes "tell your computer where to find things." Every sentence gets shorter. Every idea gets clearer.
The words themselves matter less than you might think. What really changes is the structure. When you write for a fifth grader, you cannot bury the important information in the middle of a long paragraph. You cannot assume the reader remembers something from three sections ago. You have to be direct, and you have to repeat the key points.
Why It Works
The people who read campus lessons are adults. They are smart, capable people who happen to be new to AI tools. They do not need to be talked down to. But they do need clarity. They need to know exactly what to do, in what order, without guessing.
Writing at a fifth grade level gives them that clarity. It is not about making the content childish. It is about removing every barrier between the reader and the action they need to take. When someone is learning something new, confusion is the enemy. Simple language defeats confusion.
How It Changed My Writing
This rule leaked into everything I write. Even this blog post. I catch myself reaching for complicated words and pulling back. I notice when a sentence is doing too much and I split it in two. I ask myself: is there a simpler way to say this?
Usually there is. The simpler version is almost always better. Not because complexity is bad, but because unnecessary complexity is a cost. Every word the reader has to decode is a small tax on their attention. The fifth grade rule keeps that tax low.
A Rule Worth Keeping
I have written hundreds of campus lessons now, and the fifth grade rule still catches me. I still write sentences that are too long or use words that assume too much. The rule does not make writing easy. It makes writing honest. If I cannot explain something simply, maybe I do not understand it well enough yet.
That is the real gift of this rule. It holds me accountable to my own understanding.
