Mercor skills assessment explained: the Assessments page, scoring by role, the no-AI rule, form retakes and paid work trials.
The phrase "Mercor skills assessment" covers more than one thing, which is why candidates who search for it find advice that seems to contradict itself. On Mercor an assessment can be the AI interview, a written form, a timed task or a paid work trial, and each of them has its own rules about time, retakes and the use of AI.
We wrote this for candidates who have been asked to complete an assessment or have received a work trial and want to know what they are agreeing to. It covers the Assessments page, how recommended assessments are chosen, how scoring differs by role, the integrity rules, time limits, whether a form can be retaken, and how a work trial is accepted, completed and paid. We make Verve AI, an interview copilot with mock interviews, and what we say about Mercor comes from its own documentation as it stood in October 2026.
What is a Mercor skills assessment?
Mercor uses the word assessment for any structured evaluation of a candidate. Its Assessments guide lists AI interviews and forms, adds that some roles include a cognitive or task-based assessment, and describes the work trial as a single paid assessment that comes before an offer. This article deals with the forms, the tasks and the work trial, and our guide to how the Mercor AI interview works covers the spoken part.
According to Mercor, an assessment shows a project team your domain expertise, how you approach problems that resemble real project work, whether you can follow instructions and handle ambiguity, and how clear your answers are.
Where do you find your assessments?
Every assessment linked to your account sits on the Assessments tab of the Home page. Mercor now treats that page as a main entry point to the platform and not only as a step inside an application, and it says that completing assessments is often the fastest way to be considered for work.
The top of the page holds Recommended Assessments, which are selected from your profile and resume, your domain or data-type expertise, and the active opportunities that require them. Recommendations appear only after you upload a resume, no more than two are shown at a time, and each one leaves the section once you complete it. Passing a recommended assessment means you are considered automatically for new roles that use it, even if you never submit a traditional application.
Below that section, the remaining assessments are grouped into categories such as Data Type Assessments and Domain-Specific Assessments. Each one is marked Not taken, In progress or Completed, and the status stays in step wherever you started it.
How are Mercor assessments scored?
Mercor does not publish pass marks, and the same assessment can count differently for different listings. Its guide states that the scoring and weighting may vary with the requirements of the role, so a result that qualifies you for one project may not be enough for another.
Mercor also says human reviewers may review an assessment to verify that a candidate suits a role or project. If you retake an assessment that permits it, only the most recent completed attempt is considered.
You should not expect to see a score. Mercor's support team does not provide assessment scores, detailed results or individual feedback, and feedback exists only for the assessments where it has been switched on. When it has, a link arrives in the submission email and the feedback can also appear under the assessment on the Assessments tab.
What are the rules during an assessment?
The integrity rules are short and they apply unless a particular assessment says otherwise. Mercor lists four things that a candidate may not do.
- You may not use AI or LLM tools to generate your responses.
- You may not copy content from external sources.
- You may not share answers or work on them with other people.
- You may not repost assessment content publicly, including screenshots or templates.
Some assessments switch off copy and paste on purpose, and Mercor says the restriction exists to deter plagiarism and AI-generated responses.
The broader LLM Usage Policy explains where the line sits. It allows a language model to check grammar and word choice and to refine tone lightly while the ideas and structure stay yours. It prohibits using one to rate model responses, to write justifications or to predict how code will behave, and it says that submissions evidently produced by AI will be flagged. Our article on what Mercor records and its AI rules goes through that policy in detail, and the instructions on each assessment remain the final word.
Are assessments timed, and is your work saved?
Most Mercor assessments have no strict time limit. A timed one opens with a start screen that states how long you have, and once you begin the timer runs continuously and cannot be paused. Mercor advises staying on the tab with a stable connection during a timed assessment and not reloading the page, because a reload or a dropped connection can cause an answer to be missed.
Autosave is supported, although Mercor says it is not guaranteed in every case. Its recommendations are to finish in a single session where you can, to avoid long idle periods and to keep your own copy of any long written answer. Some assessments begin with setup checks for the camera, the microphone or the screen.
Can you retake a written assessment?
Most assessments accept a single submission, so a form should be treated as final. A form can be retaken only when that particular form allows it, and an assessment that cannot be retaken opens in read-only mode after you submit. Mercor's notes on its application steps add that support should be contacted about a form retake only when it is essential.
That is why Mercor's own advice is to review every answer before submitting and to aim for your best work on the first attempt. Interviews follow a separate rule with a fixed number of retakes, which we explain in our guide on how to retake or reset a Mercor AI interview.
How does a Mercor work trial work?
A work trial is a one-time, paid assessment in which you complete a task that resembles the project before a full contract is offered. Mercor's work trial guide says it appears in the Offers tab or under Important Tasks, and that its page shows the contract type, the fixed trial payment and the trial end date. You accept it by completing a checklist in the following order.
- You sign the Terms of Work document with your name, signature and date.
- You sign the Confidential Information and Inventions Assignment Agreement.
- You acknowledge Mercor's payout policies, which refer you to the Contracts tab.
- You set up payments, using a beneficiary name that matches your identity documents exactly.
- You complete work authorization, a step that appears only when the trial requires it.
- You sign the offer letter, which makes the Accept work trial button available.
The trial becomes active as soon as you accept it, and that is also when the deadline is set. Accepting moves the deadline to two weeks after the date shown in the offer email, so the Trial end date on the work trial page is the one to follow. Mercor states that an expired trial cannot be reopened or extended, and that support cannot reinstate one.
A typical work trial takes about four to six hours, and it can be saved and completed over several sittings before the deadline. The task has to be done independently, and Mercor does not help with the content of the assignment.
How are work trials paid?
Each person is eligible for one work trial and is paid for one only, however many trial offers arrive. Accepting one does not cancel the others, so Mercor asks you to choose the one you want and to decline the rest or let them lapse.
Payment is a fixed amount and does not depend on whether you are selected for the role. It does depend on a complete, good-faith submission, and Mercor notes that it can withhold payment for low-effort or incomplete work. Once the submission has been reviewed, payment is typically processed within 14 business days, and the money usually reaches a bank three to seven business days after the payout shows as paid.
Mercor does not give individual feedback on a trial. If the project lead accepts your work you receive a final offer, and our guide to Mercor onboarding describes what follows it.
Where does Verve AI fit with Mercor assessments?
Mercor's rule is that AI tools may not be used to produce assessment answers, so Verve AI's place in this stage is interview practice and not the written forms or the work trial.
What Verve AI offers here is preparation for the spoken parts of the process. Its mock interviews run as a spoken interview with an AI interviewer, drawn from a question bank, your own questions or a job description, and end with a report. For interviews, the Mercor interview mode structures answers from your resume and keeps them consistent with earlier answers, as prompts for answers given in your own words. You can start on Verve AI's free plan, which includes five mock interviews.
