Look at the data before you buy anything.
Aventience publishes a fixed, free sample covering three districts — real, rights-cleared districts wherever possible, or a clearly labeled representative/synthetic set built to the same schema if that clearance isn't complete — selected to show real schema and edge cases, so you can review the structure, check integration effort, and decide whether this data fits your workflow before any purchase is involved. The sample isn't a measure of how much of the country is currently available; it's there to show you the shape of the data.
What the sample is
The sample is a fixed set of three districts published for anonymous evaluation — free, requiring no account, and not itself a purchase or a reservation of anything. Wherever possible, it's built from three real districts whose rights to be shown and shared this way have been specifically cleared. If that clearance isn't complete by the time this page goes live, the sample is instead a clearly labeled representative or synthetic set of three, built to the same schema — either way, the page and the download tell you plainly which one you're looking at.
The sample doesn't change, and it doesn't grow as Aventience adds more districts to its currently available release. It's a fixed snapshot, meant to answer one question: does this data, in this shape, work for what you're trying to do?
What's in the sample
The sample ships in the same structure a real order does: two views — events, with one record per calendar event or date range, and event_dates, with one record per individual calendar date inside that range — delivered in both CSV and Parquet, so you can work with whichever fits your pipeline.
Alongside the data, the sample includes a manifest describing exactly what's in the download, checksums so you can confirm the files transferred intact, and a field dictionary and five-minute quick-start guide that walks through the schema field by field and shows how to load the files, join events to event_dates by date, and interpret what you're looking at.
What it demonstrates
The sample is built to show the specific things that are easy to get wrong when handling school-calendar data yourself:
- Weekdays and weekends are explicit. A weekend that happens to fall inside a school break is clearly marked as a weekend, not miscounted as a closure.
- Events can span a date range. A single event — a winter break, for example — expands into the individual calendar dates inside it in
event_dates, so you can join by date without doing that expansion yourself. - Each district's own wording is preserved alongside Aventience's normalized category. You can see exactly how a district's original label maps to a consistent, comparable category across districts.
- Overlapping events don't get silently discarded. Where a named holiday falls inside a longer break, both are represented — one as primary for that date, one alongside it — so you don't lose information or end up double-counting the same date as more than one closure.
These are shown at a small scale specifically so they're easy to inspect by hand before you'd need to trust them at a larger one.
What it isn't
The sample is not a measure of Aventience's overall coverage. It's a fixed illustration of structure and edge-case handling — not a proportional slice of how many districts, or what share of any state or region, Aventience currently has available. Don't use it to estimate coverage in your area of interest; ask us instead, and we'll tell you directly what's currently available.
Downloading or reviewing the sample doesn't purchase, reserve, or commit you to anything. It's free, it requires no account, and there's no obligation attached to looking at it.

Ready to move forward
If the sample looks like a fit, every order gets direct attention from here. Tell us the districts, the region, or the coverage you're after, and we'll confirm what's currently available, calculate your price, and put the order together with you.
Tell us what you need, and we'll put together an order built around it.
