§ Usage · updated hourly · through Oct 2, 2026

Who uses the archive.

How often the reports in this archive are downloaded, by web browsers and by programs. We count unique downloads in the spirit of the COUNTER rules libraries use, and keep bots and crawlers out of the total.

Machine downloads · September 202627,919Scripts, integrations, AI assistants, busy browsers, and unidentified clients. 53,173 since Jul 6.
Schools with downloads731Schools whose reports were downloaded at least once in September 2026.

Self-declared bots and AI crawlers downloaded another 35,447 files in September 2026. They keep the archive findable, but we don’t count them as use.

§ 1 · Downloads over time

Every day since Jul 6

A download counts once per browser or program (IP address plus user agent), per file, per day. Reopening the same report on the same day does not add to the count. In September 2026, 9% of browser downloads started from a link on this site.

§ 2 · By kind · September 2026

Who is downloading

We sort each download by what the program says it is. Programs that open more than 30 files in a day move from browser to machine, even if they look like a browser.

API requests are not downloads. One program can ask for a thousand fields in an afternoon, so this number swings more than the download count. In September 2026, the three busiest days made up 56% of the requests. Bots and crawlers made another 5,093 requests, left out here. Before October 1, 2026 we inferred which requests came from this site; since then the site labels its own.

§ 4 · Across schools · September 2026

How downloads spread across schools

In September 2026 the typical school's reports were downloaded about 30 times, and 81% of schools with any downloads had 10 or more.

Median per school30downloads in the month

About 100 or more8111% of schools

Schools by browser and machine downloads in September 2026. School counts of 10 or more are rounded to the nearest 10. We don’t publish a ranked list of schools.

    Rounded to the nearest 10. Schools are listed for complete months with 10 or more downloads; other months show “fewer than 10” (which includes none) and are left out of the total. Counts include browser and machine downloads, not bots.

    § 5 · How we count

    One request, start to finish

    Here is what happens to a single request for a report file.

    1. Someone opens a school’s 2024–25 report in Chrome at 9:14 a.m. UTC. The file loads in three range requests, all answered with 206.
    2. We pair the IP address with the browser’s user-agent string to tell one visitor from another. The IP address stays inside the log system and is never stored.
    3. The three requests are for one file on one day, so they become one unique download.
    4. The user agent reads as an ordinary browser, and that visitor opened no more than 30 files that day, so it counts as a browser download.
    5. If the same visitor opens that report again at 4 p.m., the count does not change. Tomorrow it would count again.
    6. If the user agent had named a crawler, such as Googlebot or GPTBot, the download would go into bots and crawlers instead and stay out of the headline.

    Requests from our own pipeline and from this website’s servers are left out entirely. A day appears here once every hour of it has been counted. School numbers are published once a month is complete. A school is listed for a month only if it had 10 or more downloads, rounded to the nearest 10; for the rest we publish only how many schools there were. The counting rules are versioned; when they change, we note the date and the change below. Read the privacy page for what we keep.

    Our own serving loadIn September 2026 this website and its simple API made 4,987,704 requests to the database to serve pages and answers. That is our own cost of running the site, not use by others, so it stays out of every count above.
