# Datasets — the Washington credential register, prepared

> The 553,932 active Washington health care credentials as a dataset: fields, measured fill rates, and published prices.

## Datasets

The pages of this site are free and will stay free — a public fact belongs to nobody. What is sold is the work of compiling it.

The pages of this site are free and will stay free : **an official fact belongs to no one**. What is sold here is the compilation work — extracting the Washington health care credential register, reconciling it, dating it, and delivering it in a usable form.

### What is worth buying is the flow, not the stock

A published register is a state at one instant. What it does not publish is **the list of what has just changed** : every record carries its date, but nowhere can you ask for « everything that moved since 2016-01-20 ». To get it you have to re-read the whole file and diff it — every month.

About **6 583 credentials a month** are recorded. That is the rate at which a snapshot ages, and it is why the subscription is listed first and the snapshot last.

### What is in it

Every field below is measured on the delivered rows, not estimated. A ⚠️ marks a column the source does not contain — that is the part you cannot get for free by downloading the file yourself.

*Fields delivered and fill rate, measured on the rows actually delivered — not estimated*

| Field | Description | Filled |
|---|---|---|
| `credential_number` | The credential number, unique across the register | 100.0 % |
| `name` | Name as the Department holds it | 100.0 % |
| `credential_type` | One of 169 types, verbatim | 100.0 % |
| `legal_form` | ⚠️ License, Certification, Registration, Permit, Trainee, Endorsement — derived from the type and normalised | 100.0 % |
| `first_issued` | ⚠️ ISO date, normalised from the source's MM/DD/YYYY | 99.6 % |
| `last_issued` | ⚠️ ISO date, normalised | 100.0 % |
| `expires` | ⚠️ ISO date, normalised | 99.7 % |
| `ce_due` | ⚠️ Continuing-education due date, ISO | 58.0 % |
| `expiry_year` | ⚠️ Extracted, for grouping and alerting | 99.7 % |
| `discipline` | 0 none, 1 yes, 2 pending — as the source flag, with no reason attached because the source gives none | 100.0 % |

The 6 fields marked ⚠️ **do not exist in the source** : we add them — a join, a normalisation, or a reconstructed history. That is the part a buyer cannot reproduce by downloading the official file.

⚠️ One field of the source is **deliberately absent**
from every dataset sold here: the holder’s **year of birth**.
It is in the public file for 552,133 of these people; we do not carry it,
do not sell it, and will not add it on request. Full name plus year of birth
is an identification pair, and it answers nothing about a credential.

### What it costs

- **Change feed — USD 300 / month**Or USD 3 000 a year. At every collection, what came in, went out or changed since the previous one. This is the part that does not age.
- **One slice — USD 90 / month**The feed restricted to a single credential type, for those who do not need the rest.
- **Full snapshot — USD 4 000, once**The state of the register on the day of delivery, every field included. Listed last on purpose : a snapshot ages.

**Not a consumer reporting agency.** This site
and the datasets sold from it are **not** consumer reports under
the Fair Credit Reporting Act, and must not be used to decide anyone's
eligibility for employment, credit, insurance, housing, or any other purpose
covered by the FCRA. If you need a background check, use a screening company
that operates as a consumer reporting agency.
