- Costco does not publish a pass rate for any hiring assessment, so any specific percentage you see is unverified.
- Costco's careers guidance says some positions may require demonstrating skills or passing a business-related test.
- There is no single company-wide Costco test; the job posting and your invitation define what, if anything, you take.
- Section lists, question counts, pass marks and retake rules are reliable only when they appear in your own invitation.
Why There Is No Published Pass Rate
Search for a Costco assessment pass rate and you will find confident numbers on forums, video comments and test-prep pages. None of them come from Costco. The reason is structural: a pass rate only exists when an organization runs one standardized exam, scores every candidate against a fixed standard, and chooses to release the results. Costco's hiring process does none of those three things in a way that is visible to the public.
On this site, "CAT" is shorthand for the Costco Assessment Test. That shorthand is convenient, but it can mislead. It suggests a single named exam with a fixed format, like a licensing test. In reality, Costco's official careers guidance says only that applicants may be asked to demonstrate skills or pass a business-related test for some positions. That is a conditional statement about certain roles, not a description of one universal exam.
If you want the broader picture of what the assessment is and where it fits, start with What Is the Costco Assessment? and Costco Assessment Meaning: Where It Fits in Hiring. This article focuses on one narrow question: what can responsibly be said about pass rates, and what cannot.
What Costco Does Publish
The verifiable record is short. Costco's careers site is the official starting point for job postings and application guidance, and it is the right place to confirm anything about a specific opening: Costco Careers job listings. The relevant published facts, as checked against that source, are limited to the following.
- Some positions may ask applicants to demonstrate skills or pass a business-related test.
- The requirement depends on the position, not on a blanket company policy.
- Details for a given role come from the job posting and from any invitation you receive.
That is the full extent of what can be stated as official. Notice what is absent: no pass percentage, no historical completion statistics, no score distribution, no published cut-off. The absence is itself information. When an employer does not release outcome statistics, the honest conclusion is that the statistic is unavailable, not that it is secretly high or secretly low.
What Is Not Published
It helps to be explicit about the gaps, because these are the details that unofficial sources most often invent. Treat each of the following as unknown unless it appears in your own invitation or a Costco posting for your specific role.
| Detail | Published company-wide? | Where to look |
|---|---|---|
| Overall pass rate | No | Not available from Costco |
| Section list and domain weights | No | Your invitation or the job posting |
| Number of questions | No | Your invitation, if stated |
| Passing mark or cut-off score | No | Not typically disclosed; see invitation |
| Retake rules | No | Your invitation or recruiter |
| Time limit | No | Your invitation |
| Whether your role uses a test at all | Role-dependent | The specific job posting |

For timing and process details, Costco Assessment Timing: Invitations, Deadlines and Next Steps explains why dates and deadlines also have to come from your own invitation rather than a general calendar.
How to Treat Pass-Rate Claims You Find Online
Because the real number is unpublished, any figure circulating online falls into one of a few categories. Knowing which category you are looking at protects you from making decisions on bad data.
Anecdotes dressed as statistics
A post that says "most people pass" or "almost everyone fails" is usually one person's experience, or a small group's, generalized. It tells you nothing about the population of applicants across all roles, locations and hiring periods.
Numbers borrowed from a different test
The acronym "CAT" is shared by several unrelated credentials and exams. Pass rates, fees, domain weights and retake policies for those other programs sometimes get pasted into pages about the Costco assessment. If a figure comes with details that sound like a formal certifying body, a registration fee or a renewal cycle, it almost certainly belongs to something other than a Costco hiring screen. Our explainer on Costco Assessment Names and Acronyms Explained covers this naming confusion in detail.
Marketing numbers
Some preparation sellers cite success percentages or "pass guarantees." Without a published denominator, a pass rate for Costco's process cannot be independently audited, and a guarantee tied to a hiring decision is not something any outside party can legitimately offer. The decision belongs to Costco and the hiring team.
Why Role Type Changes Everything
Even if Costco did release an aggregate figure, it would blend together very different situations. Corporate postings may name role-specific software or typing tests, while warehouse and retail hiring can follow a different process entirely. A pooled average across these would describe no one's actual experience.
Corporate and office-type roles
Postings in this area may mention role-specific software or typing tests. The skills assessed track the work the role involves.
- Check the posting for any named software or skill requirement.
- Expect the test, if any, to mirror the job's daily tasks.
- Confirm format and timing in your invitation, not from forums.
Warehouse and retail roles
Hiring for these positions can follow a different process, and a formal test is not guaranteed to be part of it.
- Do not assume a test exists just because another role used one.
- Rely on the specific posting and any messages from the hiring team.
- Prepare for the role's real demands rather than a generic exam.

What a Result Actually Means in Hiring
A pass rate implies a clean pass/fail line. Hiring screens often do not work that way. A test result is typically one input among several, alongside your application, experience and any interviews. Costco has not published how it weighs a skills test against other factors, so claims that a particular score "guarantees" or "blocks" an offer are unsupported.
This is also why it is worth being clear about what the assessment is not. It is a hiring screen, not a renewable certification. There is no credential issued, no renewal fee and no registry listing successful candidates. If you want the full distinction, see Is the Costco Assessment a Certification? and Costco Assessment Credentials: Hiring Screen vs Certification. For interpreting whatever result you receive, What Does a Costco Assessment Result Mean? walks through realistic expectations.
Key Takeaway
Because no company-wide scoring standard is published, a "pass" is not a universal threshold you can look up. Focus on demonstrating the skills your specific posting describes, and treat your own invitation as the only authoritative source for format and scoring details.
Better Questions to Ask Instead
Candidates often fixate on pass rates because they want a sense of how worried to be. A more useful approach replaces the unanswerable question with answerable ones.
- Does my specific role use a skills test? Check the posting and any messages from the hiring team.
- What skills does the posting name? Software, typing, numeracy or other job-related abilities will usually be reflected in the listing itself.
- What does my invitation say about format, timing and scoring? This is the only reliable source for section lists, question counts and retake rules.
- Who can I ask? A recruiter or the contact named in your invitation can clarify logistics that no public page can.
If you want a sense of difficulty without relying on a fabricated number, How Hard Is the Costco Assessment? discusses what makes a screening test feel hard or manageable in qualitative terms.
Preparing Without a Pass Rate
You do not need a pass rate to prepare well. You need to know what your role asks of you and to practice those things. The short plan below ties the order of preparation to role-specific content rather than generic study habits, and it assumes you have already read your posting and invitation.
Decode the posting and invitation
- List every skill, tool or task the posting names.
- Note any format, timing or device details in the invitation.
- Flag anything unclear to ask the contact named in your invitation.
Practice the named skills first
- If software is named, spend your early sessions getting comfortable with it.
- If typing is relevant, practice accuracy before speed.
- Work on job-related reasoning and basic business tasks the role implies.
Simulate the conditions
- Match the time limit and device from your invitation as closely as you can.
- Review mistakes by category so you know which skill to reinforce.

If you want hands-on practice to build general readiness, you can try the practice tests on the main site. Keep in mind that any study-area list on this site is preparation organization, not an official Costco blueprint, since none is published.
Verification Checklist Before You Rely on Any Number
Before you let a statistic shape your confidence or your plans, run it through this short checklist.
- Source: Does it trace back to Costco's careers site or your own invitation, or only to a third party?
- Scope: Does it say which role, location and hiring period it covers?
- Identity: Is it actually about the Costco hiring assessment, or about a different test that shares the "CAT" acronym?
- Specificity: Does it promise a guarantee or a precise percentage with no method behind it?
- Freshness: Could the process have changed since the information was posted?
If a claim fails these checks, discard it. If you are weighing whether preparation is worthwhile at all, Is Costco Assessment Preparation Worth Your Time? and Costco Assessment Costs and Optional Preparation will help you decide how much to invest. Pay questions belong in a separate conversation; Costco Pay: How to Evaluate the Role and Offer explains how to evaluate an offer without relying on invented figures, and Costco Application Requirements: What to Check Before Applying covers what to confirm before you apply.
