The score measures whether work was delivered, whether it was on time, whether anything was disputed, and how much of that a third party confirmed. Your degree, your job title, the name of the company you worked for, how long you stayed and what you pay Credda are all outside it.
What is inside the calculation
Five factors.
Completion rate. Commitments fulfilled against commitments made.
On-time rate. Delivered by the agreed deadline. The longer the delay, the greater the effect, and a job delivered very late still keeps some credit rather than none. Years late is far worse than a few days late.
Dispute history. Disputed commitments as a share of the record. A clean record earns this in full.
Verification depth. The share of the record a third party independently confirmed. It is confirmed divided by claimed, so recording outcomes nobody confirms lowers it.
Verified professional grounding. One narrow employment term, described below.
How much each factor counts is published live by Credda and read from there by the app every time a page renders, so it is not typed into this guide. The trust page shows the current figures.
The one thing employment history does
Verified professional grounding asks a single yes or no question: has at least one past employment role been confirmed by a third party.
One confirmed role counts exactly as much as fifty. A role you stated yourself counts as nothing. The employer's name is never read. No dates and no length of service enter it. It can only ever add, and only on the upside, so it can never rescue a failing record.
That is the whole of what employment history does to the number.
What is recorded but never scored
Education, skills, certifications, projects and achievements can all be recorded, shown on a profile, and confirmed by a witness. None of them can move a score, confirmed or not.
Two care coordinators with the same confirmed record of shifts delivered on time have the same score. One has a master's degree and one left school at sixteen. The degree is on the profile. It is not in the number.
Credda publishes this as data rather than as a promise: prestige is not an input, and neither is duration. The reason is that the score exists to say how somebody delivers work, and a school name does not say that.
Money does not move it
No plan, at any price, moves the payer's own score. There is no route by which it could.
There is one nuance, and stating half of it is worse than saying nothing. An organization's active paid or comped plan is one of four alternative signals that let that organization's confirmations count as verified evidence for its workers. That is about establishing that the employer is real, not about buying a number, and payment is never required: three of the four routes cost nothing, and a real two-person business is cleared by a person rather than by paying. A worker's reliability never depends on their employer's plan.
No human and no AI decides a score
The score is a fixed calculation over the record. The same record always produces the same number. No member of Credda staff can adjust it and no AI is in the loop. Anything on the site labeled as an insight or a summary is commentary sitting beside the number, never an input to it.
Other things people assume count, and do not
The relationship a confirmer states, such as manager, client or colleague. It is optional and never an input.
The verification meter on your profile settings, which measures how much of your profile is confirmed and is a different thing from the scoring factor of a similar name.
An organization's own work score. It never feeds anyone's portable score, and no employer can move somebody's portable record through it. Work done for an employer reaches the portable score only as individual confirmed outcomes.
Industry, badges, timeline text and the number of platforms you connect.
Time counts, but nothing is thrown away
Older outcomes count for less as time passes, at a decay rate Credda publishes. Nothing is ever dropped. A job confirmed three years ago still counts, and counts less than the same job confirmed last month.
Do not read anything more precise than that into it. How much an individual outcome weighs also depends on the rest of the record, so there is no honest "your outcome halves in so many days" figure to quote.
