You have been there. You have a task—a new scheme of work, a letter to parents about a school trip, or a summary of the latest DfE guidance. You turn to Gemini, give it a prompt, and in seconds, it produces a draft.
For a moment, you feel a sense of relief. The blank page is gone. The text is plausible, the grammar is correct, and it looks like a finished piece of work.
But then you start reading it closely. The relief fades and a familiar, nagging frustration sets in.
The draft is generic. It lacks your school's voice. It misses the key strategic point you needed to make. It is good, but it is not right. It is 80% of the way there, but that final 20% is a gap you can't seem to cross. Without that last piece, the entire document is unusable for any serious educational purpose.
This is the "80% Problem."
And it is the single biggest reason educators and business leaders feel disappointed with AI.
“AI is the world's best intern. It is fast, eager, and has read every book in the library. But it has zero life experience. You are the Editor-in-Chief.”
— Alex Harvey
Why Does AI Stop at 80%?
The frustration you feel is justified. It comes from a mismatch between what we expect AI to be (an expert colleague) and what it actually is (a very sophisticated pattern-matching machine).
It consistently falls short because it lacks three ingredients that are uniquely human.
1. Lack of Specific Context
An AI model knows what a school policy generally looks like, but it doesn't know your school. It doesn't know your school's specific ethos, the unique needs of your Year 9 class, or the subtle dynamics of a staff meeting. The AI is best understood as a new apprentice on their very first day. It has general skills, but you would never ask it to write a crucial email to parents without a detailed briefing.
2. No Strategic Understanding
Your work isn't just about completing tasks; it's about achieving goals. The purpose behind a document—the why—is everything. Are you writing a report to reassure anxious parents or to challenge a department to think differently? The strategy dictates the tone, the structure, and the points you choose to emphasise. AI has no concept of strategy. It simply executes an instruction.
3. Zero Real-World Experience
The most valuable insights often come from experience. You remember the Ofsted inspection that went well last year, the specific objection a particular governor always raises, or the successful turn of phrase that won over the PTA. This lived experience gives your work nuance, authority, and authenticity. AI has no experience. It can simulate a confident tone, but it can't embed genuine, hard-won wisdom into its work.
The Solution: The "Human-in-the-Loop"
The secret to solving the 80% Problem isn't to find a "better" AI that can read your mind. The secret is to change your role.
You must move from a Creator (writing from scratch) to an Editor (refining and strategising).
This is the "human-in-the-loop" approach. You use the AI for what it is good at—overcoming the blank page and producing a solid first draft—and you use your human expertise for what it is good at: adding context, strategy, and nuance.
The New Workflow
- Step 1: The AI Draft (The 80%). Give Gemini a clear P.I.T.C.H. instruction to create the initial version. This saves you the mental energy of starting from zero.
- Step 2: The Human Polish (The 20%). This is where you earn your salary. You verify the facts. You adjust the tone. You inject the specific context that only you know.
- The Result: A professional document produced in a fraction of the time, but with all of your authority intact.
Why This is Good News
I often hear people worry that AI will replace them. The existence of the 80% Problem proves why that won't happen.
If AI could do 100% of the job, we would be in trouble. But it can't. It needs you to cross the finish line.
The goal of my training isn't to teach you how to automate your job away. It is to teach you how to automate the drudgery—the formatting, the summarising, the drafting—so you have more time for the 20% that actually matters: leading, teaching, and connecting with people.
