Trade test pre-deployment, process, formats, and what employers should require

The trade test is the part of foreign-worker recruitment where the corridor either delivers the worker the demand letter described or sends a different worker entirely. A welder filing on a Mumbai PoE demand letter as EN ISO 9606 3G certified, who arrives in Pula and cannot strike a clean root pass, has cost the employer 14 weeks of mobilisation cycle, a flight, and a labour inspector's note in the file. The trade test, run properly, catches the gap before the visa stamping. This article covers what trade testing looks like for the trades Werklist runs most often, what formats employers should require, and what the pre-filing pack should contain when the shortlist lands on the buyer's desk.

What the trade test is, and what it is not

A trade test is a structured, supervised assessment of a candidate's actual ability to perform the trade named in the demand letter. It is not a CV review, not a chat about prior employers, and not a verbal walkthrough of a procedure. The trade test puts the welder on a coupon, the CNC operator on a control panel (or simulator), the electrician on a wiring diagram, the forklift driver on a forklift. The artefact at the end of the test, a weld coupon, a machined part, a wired circuit, a completed load cycle, is the document the employer can inspect.

The trade test sits between CV screening and medical clearance in the mobilisation timeline. CV screening filters obvious mismatches; the trade test filters the candidates who can describe the work but cannot do it. An industry standard references "skill testing and evaluation" in its vetting vocabulary without specifying the format, which is a useful negative example, the marketing version of trade testing is to mention the phrase. The operator version is to run the coupon and document the result.

The trade test is also not a substitute for destination-country certification recognition. A welder who passes a 6G test in Kathmandu still needs the destination-country code recognition (Schweißerprüfung in Germany, AWS D1.1 endorsement in the US-aligned GCC, EN ISO 9606 European mutual recognition). The pre-deployment test confirms the candidate's actual capability; the destination certification confirms legal authorisation to perform the trade at the destination.

Trade test by trade, formats Werklist actually runs

Welder (MAG/MIG/TIG, 3G and 6G)

The standard welder trade test runs a coupon assessment in the destination's expected procedure. For a 3G plate welder destined for structural steel work, the test coupon is a 12 mm carbon steel plate, vertical-up, single V-groove, with the candidate striking root pass, hot pass, fill, and cap inside a published time window. The coupon goes for visual inspection, dye-penetrant or radiographic testing depending on the destination requirement, and bend-test if the corridor (offshore, pressure-vessel) demands it. For a 6G pipe welder destined for offshore or shipbuilding pipe spool work, the coupon is a 6-inch schedule 80 pipe, fixed at 45 degrees, with the same root-hot-fill-cap sequence, NDT-tested afterwards. The video record of the entire test sits in the candidate file alongside the coupon's NDT result.

The test is run at a Werklist-affiliated facility in Mumbai, Kathmandu, or Sarajevo, or at a partner facility under our supervision. The certifying engineer signs off. The certificate references EN ISO 9606-1 for European destinations, AWS D1.1 for US-aligned destinations, or ASME IX for pressure-vessel work, whichever code the destination employer's project specifies in the demand letter.

CNC operator

CNC trade tests run on either a real machine at the testing facility or on a control simulator (FANUC, Siemens 840D, Heidenhain, depending on the destination employer's control system). The candidate is given a part drawing, a tool list, and a published time window. The candidate writes or edits the program, sets the tool offsets, runs the first piece, and measures the result against drawing tolerance. The output is the measured part, the program file, the setup notes, and the video record. Some corridors require additional fixturing skill, clamp setup, work holding, edge finding, and the test covers these as separate task blocks.

Electrician

Electrician testing splits by destination code. UK and European destinations under the IEC 60364 family require demonstration on wiring diagrams (single-phase and three-phase), distribution board work, RCD/RCBO installation, and earth-bonding. GCC destinations under Saudi SBC or UAE-adopted standards run a similar test with destination-specific code references. Industrial electricians for shipbuilding or process plant add COMPEX-equivalent assessment for hazardous area wiring. The test artefact is the completed wiring panel and the candidate's verbal walkthrough of the safety logic.

Forklift driver, scaffolder, mason, kitchen staff

Each blue-collar trade has its own test format. Forklift operators run a load cycle on the relevant truck class (counterbalance, reach, narrow-aisle) with timed positioning and a stack-and-place sequence. Scaffolders erect a published section against the relevant code (TG20:21 for UK-aligned destinations; equivalent for Germany). Masons lay a wall section to drawing tolerance. Kitchen staff produce a 30-minute timed plate against a published recipe and a destination-aligned hygiene checklist. Each test has its own artefact and its own video record.

What the video record adds

The video-documented trade test is the practice that closes the gap between the test on paper and the worker the employer collects at the airport. The video shows the candidate's hands on the work, strike, posture, grip, recovery from error. For a welder, the video shows the run-out at the end of the cap pass, the grip on the torch, the technique on the restart. A hiring engineer at the destination can review the video before the candidate boards the flight and flag a question the static certificate cannot answer.

Industry analysis notes the absence of video trade test content on the live site, the phrase appears in industry discussion but not in the operator's published vocabulary. Werklist publishes the video record as standard practice. Every trade-tested candidate has a video file in the pre-filing pack the employer receives at the milestone-payment shortlist gate.

What the pre-filing pack should contain

The pre-filing pack is the deliverable the employer should expect at the shortlist gate, the first of the four milestone payment gates. For each shortlisted candidate the pack carries:

1. Trade test result certificate, signed by the certifying engineer, referencing the relevant code (EN ISO 9606, AWS D1.1, ASME IX, IEC 60364, etc.).
2. NDT or measurement report for the test artefact (welds, machined parts, electrical panels), with the inspector's signature.
3. Video record of the test, time-stamped, showing the candidate's full execution.
4. CV with verifiable employment history, including prior employer contacts the employer can call.
5. Medical fit-test clearance summary (full medical sent at the next gate).
6. Language screening result (A1 German, B1 Croatian, basic English, or the destination's equivalent), where applicable.
7. Document set, passport, prior certifications, training records.

The pack is the employer's basis for shortlist approval. Without the pack, the agency is asking the employer to approve a name on a list. With the pack, the employer is approving a documented capability against the demand letter spec.

What employers should require in the master services agreement

Three trade-test clauses belong in the MSA. First, the right to require a specific test format per role line, some destinations demand 6G pipe over 3G plate, some require AWS D1.1 over EN ISO 9606. Second, the right to attend or review the trade test, in person or via the video record, before approving the shortlist. Third, the agency's commitment to replace any worker who fails an equivalent test at the destination within the published probation window, at no second sourcing fee, the replacement guarantee tied directly to the test that the agency ran.

Werklist runs trade tests for every shortlisted candidate on every corridor and delivers the pack as the standard shortlist artefact. See /contact-companies, send the role spec, the headcount, and the destination, and we come back inside one business day with the test format recommendation, the certifying facility, and the corridor's expected pass rate.
