Every spring I put together a cart for the lab. Cables, drives, tool kits, replacement parts. Twenty or thirty line items.
Then comes the part nobody warns you about in credential school: writing a justification for each one. Why does a CTE classroom need a cable tester. Why these headphones. Why fourteen flash drives.
The purchases are obviously justified. I just have to say so, item by item, in language a business office will accept, with standards codes attached. It takes an afternoon. It is the least valuable afternoon of my year.
So I built something to do it.
What It Does
I upload a screenshot of my shopping cart or a PDF invoice. It reads every line item and returns a finished justification document: product name, SKU, price, quantity, vendor, a paragraph on how it supports student learning, and the relevant California CTE ICT standard codes. A summary table at the bottom.
Formatted in markdown, so it pastes clean into Canvas or a Google Doc without me fixing bullets for ten minutes.
Twenty items in about a minute.
Why It Works Better Than You'd Expect
The standards codes live inside the prompt. That's the whole trick.
I pasted in the actual ICT standards I cite most: health and safety, technical knowledge, the pathway standards for Information Support, Networking, and Software Development. Now the AI isn't guessing at codes from memory. It's picking from my list.
That one change is the difference between a document I'd submit and one I'd have to rewrite.
Two Things You Have to Change
The header. It has my name and room number in it. Swap in yours before you use it.
The standards. These are California CTE ICT standards. If you're in another state or another program area, replace that whole reference block with your own codes and descriptions. That's the real setup work, and it takes maybe twenty minutes with your standards document open. You do it once.
Read Before You Submit
The justifications are persuasive by design. That's the job. But I still read every one before it goes to the business office, for two reasons.
It will occasionally reach on a standard. A cable tester genuinely maps to B2.3. A box of pens does not map to anything, and if the AI insists it does, that's the sentence that makes an approver skeptical of the whole document. I delete those and write one honest line instead.
And it doesn't know my program. It writes a good general justification. I know why I specifically need that item for what my students are building in November. Adding one sentence of that makes it a much stronger ask.
First draft, not final draft. But the first draft was the part eating my afternoon.
Build It Once
Set it up as a ChatGPT Project or a Gemini Gem. Paste the instructions in, swap your header and your standards, and it's ready for every cart you build from now on.
Instructions
Paste everything below into your Project or Gem instructions. Change the two bracketed sections marked SWAP.

ACCURACY RULES
- Cite only codes from the reference list above. Never invent a code or
recall one from outside this list.
- If an item does not credibly align to any listed standard, say so
plainly in the justification field rather than forcing a match. Write:
"No direct standard alignment. Recommend a brief operational
justification instead."
- Do not overstate. A justification an approver finds implausible weakens
the entire document.
- If a field cannot be read from the uploaded file, write "N/A" rather
than guessing.
