Field Trip Notice System Synced to the Gradebook is a startup idea for teachers and school administrators. Teachers learn about a field trip pulling students out of class 30 minutes before it happens, and must reshuffle tests and grades on the fly. A thread in r/Teachers drew 121 upvotes and 172 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Email chains and School calendars, and that still leaves this job open. Hotness is 3.35, Warm. Real but moderate pain. Price-sensitive audience. The thread drew 121 upvotes and 172 comments. Only clumsy or enterprise-only options. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced between $50 and $199 a month and charged as a B2B subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Who has it

Teachers and school administrators.

What people use now

  • Email chains
  • School calendars

A way through

A school module that syncs field-trip schedules with the gradebook, notifies affected teachers a set minimum ahead and blocks retroactive trips.

MVP scope

  • Give teachers and school administrators a way to do this in one sitting: Auto-notify affected teachers with a minimum lead time and block last-minute field trips.
  • Persist the result and show it again after a reload.
  • State the empty case when there is nothing to show yet, with one next step.
  • Charge later with a B2B subscription, between $50 and $199 a month. The free path must finish the core job once.
  • Ship the web app only. Leave Email chains to keep the jobs they already do well.

Questions

Is this idea already taken?

People already use Email chains, School calendars. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.

How hard is a first version?

Moderate. A tight MVP is about 3 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.

Who would pay, and how?

The audience is teachers and school administrators. Charge a B2B subscription, and test a price between $50 and $199 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.

Can I use the evidence?

Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
