Vector | WA is a Washington State legislative intelligence tool. It reads the public legislative record and turns it into plain-English summaries and a 0–99 trajectory score. This page explains where the data comes from, how the signals are generated, what Vector | WA is — and, just as important, what it is not.
What Vector | WA is — and isn’t
Vector | WA is an information tool, not a professional adviser. Nothing on Vector | WA is legal, financial, political, or lobbying advice, and it is not a substitute for a licensed professional or for the official legislative record. Vector | WA is nonpartisan: it does not endorse candidates, take positions on legislation, or recommend how anyone should act. Its job is to make the record easier to read.
Independent and not affiliated
Vector | WA is an independent project. It is not affiliated with, endorsed by, sponsored by, or speaking for the Washington State Legislature, any legislator, the Office of the Governor, any state agency, or any government body. References to the Legislature and to public officials are for identification and commentary only. Vector | WA is not a registered lobbying entity and does not represent clients before the Legislature or any agency.
Data sources and freshness
Vector | WA pulls from the Washington State Legislature’s public records: bill text, committee actions, roll calls, fiscal notes, and floor calendars. The data is mirrored nightly into Vector | WA’s database. Between syncs, the site reflects the state of the record at the last refresh, not the live docket. A timestamp on each bill page shows the last sync. The data may be delayed, incomplete, or contain errors.
How signals are generated
Every bill receives a trajectory score from 0 to 99. The score is a weighted composite of five signals (committee placement, vote margins, fiscal note status, calendar movement, and companion status), adjusted by documented X factors when a bill sits outside the ordinary procedural path. Scores are bucketed into four tiers: HIGH (75 to 99), MODERATE (60 to 74), LOW (45 to 59), and VERY LOW (0 to 44). Bucket thresholds are calibrated across three biennia (2021-22, 2023-24, and 2025-26 — 8,062 bills) of Washington State session data and rechecked each session. See the methodology page for the full calibration table.
Algorithmic authorship
Scores, tiers, and momentum indicators in Vector | WA are produced by algorithm, not by a human analyst. No human writes or reviews individual bill scores before they appear on the site. Bill summaries on each bill page are generated by a large language model from the bill’s official text and metadata, also without individual human review. Summaries may be incomplete or contain errors. Always confirm anything you rely on against the official bill text, which is linked on every bill page. The underlying bill text and procedural record come directly from the Washington State Legislature.
The score is an estimate, not a prediction
A trajectory score is a signal about where a bill is likely heading based on its procedural record. It is not a prediction, a guarantee, or a probability in the strict statistical sense. Bills with identical scores can and do reach different outcomes. Vector | WA makes no representation that any score will correspond to any particular legislative result.
Interim-period framing
Between legislative sessions, trajectory scores reflect a bill’s terminal position in the most recent session, not its prospects in the next one. Carry-over and prefile activity are labeled separately. Users should treat interim scores as historical, not predictive.

Privacy and data handling
Vector | WA collects only what it needs to run. If you create an account, that means your email address; if you build a watchlist, save tags, or write notes, it means those items. The site uses privacy-friendly, cookieless analytics to count page views in aggregate; this does not track you across sites or collect personal information. Vector | WA does not sell personal information. Bill, member, and committee data on the site is public information from the Washington State Legislature.
