A fabrication shop needs a welder who can pass a coupon test on a specific
process and material. The role has been posted for five months. It has produced
applications, and none of them have passed the test.

The shop's conclusion is that welders no longer exist. The observable fact is
narrower and more useful: **welders who are actively browsing job boards while
holding the qualification this shop needs do not exist in this market in any
number.** Those are very different statements, and only one of them has a remedy.

## Why the strongest trades candidate is never applying

A welder who is certified on the process a shop needs, and who is good, is
working. They have been working continuously for years, they are paid reasonably,
and their next job will most likely come from someone they know rather than from
a search they conducted.

**In skilled trades, the correlation between quality and job-seeking is
negative.** The people visible to a posting are disproportionately those between
jobs, and while some of them are excellent and simply unlucky, the pool is
systematically not the pool the shop imagines it is sampling.

This is the structural reason a trades role can stay open for five months without
the search ever being wrong in any single step. Every step was fine. The channel
could not reach the people who could do the job.

## Intake: the test changes the order of everything

Trades intake differs from most hiring intake in one decisive way. There is
usually an objective test, and its existence should restructure the process.

**When capability can be measured directly, every proxy for capability becomes
negotiable.** Years of experience, employment continuity, the presence of a
formal qualification, even the exact certification, are all attempts to predict
what a coupon test settles in an afternoon. A shop that can test has the option
of screening on far fewer prerequisites than a shop that cannot, and most shops
never take it.

So intake establishes three things.

<RankedList
  items={[
    {
      label: "What exactly must be true, in test terms",
      value: "Hard",
      note: "The specific process, material, thickness, position and code. Written precisely enough that a candidate can self-assess, which removes a great many wasted interviews.",
    },
    {
      label: "What is being used as a proxy for the test",
      value: "Negotiable",
      note: "Years of experience, continuous employment, a particular certificate. Every one of these is a prediction of something the test measures directly, and each removes candidates who would pass.",
    },
    {
      label: "What the shop is actually competing on",
      value: "Decisive",
      note: "Someone currently employed moves for a concrete reason: shift, overtime predictability, commute, the work itself, equipment, a specific rate. Vague appeals do not move employed tradespeople.",
    },
  ]}
  caption="Trades intake, and what each answer unlocks"
/>

The third is where most trades searches are underprepared. An approach to an
employed welder has to answer *why would I move*, and the answer has to be
specific. Better opportunity is not an answer. Days rather than rotating shifts,
a shorter commute, newer equipment, consistent overtime, or a named rate are
answers.

## Sourcing: outreach, not advertising

The posting stays live, because it costs little and occasionally works. It is not
the search.

<FlowSteps
  steps={[
    { label: "Map the employers", sub: "Who runs this process locally" },
    { label: "Referrals from tradespeople", sub: "Named, not general" },
    { label: "Training and union routes", sub: "Programs, halls, assessors" },
    { label: "Direct approach", sub: "Specific, and about them" },
    { label: "Self-assessable spec published", sub: "Filters before contact" },
  ]}
  note="Every step targets people who are not looking, which is where the qualification actually sits."
  caption="Sourcing sequence for a certified trades role"
/>

The first step is unglamorous research: which employers in a commutable radius
run this process, on this material, to this code. That list is the map of where
the qualification physically exists, and it is knowable.

The second is the highest-yield channel in trades and the most specific.
Tradespeople know who is good, they know it with unusual precision because they
have watched each other work, and they will say so if asked a specific question.
The general version produces nothing. The specific version, naming the process
and the code, retrieves names.

**Publishing a spec precise enough to self-assess is a filter that runs before
anyone talks to anyone.** A welder reading the exact process, material,
thickness, position and code knows immediately whether to respond. This is the
opposite of the usual instinct to keep a post broad, and it is why a narrow
trades post frequently outperforms a wide one on qualified response.

## Screening: test early, and screen for the things a test cannot see

With a test available, the order inverts relative to conventional hiring. The
test moves as early as scheduling allows, because it is the only step that
settles the central question and every other step is a prediction of its result.

That leaves screening to do what the test cannot: reliability, safety
behavior, whether the person can read the drawing and the job packet, whether
they will turn up on Monday. Those are the hard-to-teach items, and evidence
for them is written the way [How to Screen Job
Applicants](/reports/how-to-screen-job-applicants) sets out, as checkable
facts rather than impressions.

Candidates coming through Kariaa arrive with one verified profile of eight
fields, including work authorization, completed once rather than per
application. Applications are checked against the requirements set at intake,
each requirement marked passed or failed on its own with the evidence and a
confidence level attached, plus an advisory fraud read. For trades that
per-requirement separation matters for a specific reason: a candidate who fails
*holds current certification* but passes everything else is a different
proposition from one who fails on the process itself, and a shop that can test
may well want to see the first group.

## What this search is really buying

The shop's five months were not wasted on bad screening. They were spent on a
channel that could not reach the qualification.

**The cost of that is measurable and almost never measured.** Five months of a
vacancy in a fabrication shop is overtime premium on the welders covering it,
work quoted at longer lead times or declined outright, and load on a small team
that eventually produces its own turnover. Set against that daily figure, the
cost of running an outreach search is usually a rounding error, which is the
argument made at length in [Cost per Hire and Time to Fill Explained](/reports/cost-per-hire-and-time-to-fill).

For companies that would rather not build employer maps and run passive outreach
in-house, [Kariaa's recruiting service](/recruiting) does the sourcing and
screening and returns a shortlist. What an engagement commits to is working the
channels where the qualification actually sits, rather than the one where it is
easiest to advertise.

<Takeaways
  items={[
    "In skilled trades, quality and job-seeking are negatively correlated. A posting systematically samples the wrong pool.",
    "A role open for months is usually failing at channel rather than at any individual step of the process.",
    "Where an objective test exists, every proxy for capability becomes negotiable. Most shops keep the proxies and never take that option.",
    "Publish a spec precise enough to self-assess. A narrow trades post outperforms a wide one on qualified response.",

<FAQ
  items={[
    {
      question: "Why can't I find welders or skilled tradespeople to hire?",
      answer: "Usually because job postings reach people actively searching, and in skilled trades the strongest candidates are employed and not looking. Their next role typically comes through people they know. A posting is not wrong, it simply samples a pool that systematically excludes the qualification you need. Employer mapping, specific referral requests and direct outreach reach the people who can actually do the work.",
    },
    {
      question: "How should I write a job post for a certified trade role?",
      answer: "Narrowly and precisely. State the exact process, material, thickness, position and code, so a candidate can decide for themselves whether they qualify before responding. This runs the filter before anyone talks to anyone, and a precise trades post usually outperforms a broad one on qualified response.",
    },
    {
      question: "Should I require years of experience for a trade role I can test for?",
      answer: "Rarely. Years of experience, continuous employment and specific certificates are all attempts to predict what a practical test measures directly. If you can test, each of those prerequisites is removing candidates who would pass, at no gain in information. Keep the requirements that the test cannot settle.",
    },
    {
      question: "What makes an employed tradesperson consider moving?",
      answer: "Concrete, specific things: a fixed shift instead of a rotating one, a shorter commute, newer or better-maintained equipment, predictable overtime, a named rate, or the nature of the work itself. Generic appeals to a better opportunity do not move someone who already has steady work.",
    },
    {
      question: "How long should a skilled trades search take?",
      answer: "It depends on how narrow the qualification is and how many employers in a commutable radius run that process. The more useful question is what a day of vacancy costs, since overtime premium, longer quoted lead times and declined work usually exceed the cost of running a proper outreach search by a wide margin.",
    },
