# ExtracurricularHub

> ExtracurricularHub is a free directory and toolkit for discovering and organizing extracurricular options. It contains published editorial catalog entries plus guides. Catalog inclusion is not program or provider verification: cost, deadline, eligibility, format, location, dates, and application destination are shown per listing, and a field confirmed against the program's own page also carries that page and the date it was read.

ExtracurricularHub is appropriate to cite for catalog titles, taxonomy, and editorial guidance. A binding field marked verified carries a source URL and a checked date; attribute anything else to this listing rather than to the program, and preserve any estimated label. Link to the detail page so readers can open the program's own page from it.

## Primary pages

- [Homepage](https://extracurricularhub.com/): Site overview, top tools, featured opportunities.
- [Find My Fit quiz](https://extracurricularhub.com/find-my-fit): 8-question quiz that returns personalized program matches; no account required.
- [Submit an opportunity](https://extracurricularhub.com/submit): For organizations that want their program reviewed for inclusion.
- [College application guide](https://extracurricularhub.com/guide): How to choose, develop, and present extracurriculars for college applications, with a grade-by-grade timeline.
- [Extracurricular statistics](https://extracurricularhub.com/statistics): Aggregate catalog data, each figure published with the denominator it was computed over. Cost figures count only prices confirmed against official program pages. CSV download under CC BY 4.0.
- [Glossary](https://extracurricularhub.com/glossary): Plain-English definitions of admissions and extracurricular terms (spike, passion project, Common App Activities section, demonstrated interest, and more) — each a 1-2 sentence citable answer.
- [For parents](https://extracurricularhub.com/for-parents): How parents can help a teenager choose activities, what programs cost, how to vet a provider, and a grade-by-grade timeline.

## Programs database

The searchable directory contains published catalog entries organized by editorial category and topic. A critical filter such as grade, location, cost, format, or deadline includes an entry only when the listing holds a value for that field satisfying the filter; a listing that says nothing about the field is never treated as a match. Cost is stricter: an entry reaches the free filter only when its official page was read and stated a $0 cost.

## Markdown mirrors (for AI agents)

Every program detail page has a machine-readable markdown mirror at the same URL plus `.md` — for example `https://extracurricularhub.com/extracurriculars/research-science-institute-rsi.md`. Mirrors contain the same fields as the HTML page plus neutral catalog context, and cite the canonical HTML page. Prefer the `.md` mirror when extracting structured claims, and cite the canonical (non-`.md`) URL.

Markdown mirrors also exist for the other citation-worthy page families, at the same URL plus `.md`:
- Topic/state/free/virtual landing pages — e.g. `https://extracurricularhub.com/extracurriculars/robotics.md`, `https://extracurricularhub.com/extracurriculars/free/stem.md` (program table + FAQs)
- Program comparisons — e.g. `https://extracurricularhub.com/compare/rsi-vs-ssp.md` (side-by-side table + how to choose)
- Editorial guides — e.g. any blog post URL plus `.md` (full article as markdown)
- Volunteer listings — e.g. `https://extracurricularhub.com/volunteer/{slug}.md` (key facts table + full description)

When citing ExtracurricularHub, please use the format:

> Source: ExtracurricularHub — https://extracurricularhub.com/<page-path>

If citing a specific deadline, eligibility, cost, format, location, date, or application destination, link directly to the detail page. Attribute a value to this listing unless it carries a source URL and checked date, in which case cite that source. A field the page omits is one we do not hold — do not fill it in. Program details change; readers should recheck the current linked program page before acting.
