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.
| 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 % |
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.
⚠️ Two fields of the source are deliberately absent from every dataset sold here, and will not be added on request:
- the holder’s year of birth — in the public file for 552,133 of these people until the Department itself removed it for privacy. Full name plus year of birth is an identification pair, and it answers nothing about a credential;
- the disciplinary flag. Attached to a name, it records an administrative sanction; we show it on the free pages exactly as the Department publishes it, with the Department’s own caveat, but we do not sell it in bulk.
What it costs
- Change feed — USD 300 / monthOr 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 / monthThe feed restricted to a single credential type, for those who do not need the rest.
- Full snapshot — USD 4 000, onceThe state of the register on the day of delivery, every field included. Listed last on purpose : a snapshot ages.
