The Tanium Candidate Handbook fee table lists the TCO exam at $225, collected by Pearson VUE at registration or covered by a prepaid voucher.
Both the current TCO v1 and the incoming TCO v2 carry 60 items, per Tanium's official exam overview.
TCO v1 runs 105 minutes with multiple choice and simulation items; the v2 arriving in September 2026 runs 102 minutes, multiple choice only.
Fail once and you wait 7 days to retake; later failures push the wait to 14 and then 21 days, at the full $225 each time.
What the TCO Exam Actually Tests
TCO is Tanium's entry-level certification. Tanium's own track description says it serves to identify candidates who demonstrate core foundational knowledge and skills of basic functionality, and the published candidate profile expects one to three years of IT operations or security experience plus three to six months of hands-on Tanium time. The recommended training is the Getting Started with Tanium and Tanium Essentials courses.
The timing detail that matters right now: Tanium is mid-transition between two versions. The current TCO v1 - 60 items mixing multiple choice and simulation, 105 minutes - retires in late October 2026, and a streamlined TCO v2 - 60 multiple choice items only, 102 minutes, aligned to the Getting Started with Tanium course - arrives in September 2026. Tanium's own exam guide strongly encourages waiting for v2 if your timeline allows, because the v1 simulation items run on an older console interface. Exact dates are announced in the candidate portal, so the version you face depends on your booking window - and we confirm that before anything is scheduled.
The blueprints tell you what kind of exam this is. On v1, Refining Questions and Navigation and Basic Module Functions each carry 23%, Asking Questions 22%, Report Generation and Data Export 17%, and Taking Action 15%. On v2, Deploy an Action to Endpoint(s) carries 32% and Query Endpoint Data 31%, with Platform Functions at 22% and Presenting Refined Endpoint Data at 15%. Either way, this is a console-fluency exam: querying endpoints, refining and merging questions, targeting and deploying actions, and exporting what you find.
One honesty note you will not get from most prep sites: Tanium does not publish a passing score. The Candidate Handbook states exams are pass/fail and that passing score requirements are not published because they are determined through statistical analyses and subject to change. Any site quoting an exact TCO pass percentage is guessing. What Tanium does publish is the blueprint below, the item counts, and the seat times - and that is what this page is built on.
| # | Blueprint domain | Weight |
|---|---|---|
| 1 | Asking Questions (query endpoints, saved questions, network efficiency) | 22% |
| 2 | Refining Questions (targeting, drill-down and merge, groups and tags) | 23% |
| 3 | Taking Action (make and verify endpoint changes, scheduled recurring actions) | 15% |
| 4 | Navigation and Basic Module Functions (module tasks, historical results) | 23% |
| 5 | Report Generation and Data Export (exports, reusable reports) | 17% |

At Home via OnVUE or at a Pearson Test Center
Tanium's certifications page states the delivery plainly: Tanium Certifications exams are delivered by Pearson VUE and are available at authorized testing centers or remotely in an online proctored format. The Pearson VUE Tanium program page names the two methods - a Pearson test center, or OnVUE Online Proctored, where the exam runs from your home or office while an offsite Pearson live proctor monitors the session.
The at-home route carries published rules worth knowing before you book. Check-in opens 30 minutes early; arrive more than 15 minutes late and the exam cannot be started. All communication with the proctor is in English. You present a current, unexpired government-issued ID with a photo and signature - passport, driver's license, national or state ID card, or alien registration card - and restricted IDs such as US military IDs are not accepted for online testing.
Scheduling runs through the Tanium Career Certifications portal into Pearson VUE, and every candidate accepts Tanium's Candidate Agreement on exam-content confidentiality. Results are typically available within 24 hours in your candidate profile; pass and the Credly digital badge follows, miss and you get section-level performance information with the retake clock.
What the TCO Attempt Costs, Including the Retake Math
The Candidate Handbook fee table lists the TCO exam at $225. Payment is collected by Pearson VUE at registration, or you can sit on a prepaid voucher - voucher SKUs are on the Tanium Price List through your Tanium account team, each voucher covers exactly one attempt, and vouchers are valid for up to 12 months with no extensions granted.
The rescheduling rule is strict: cancel or move the appointment at least 48 hours ahead or the exam fee is forfeited, and a no-show forfeits it too. The retake ladder is where budgets break - a failed first attempt means a 7-day wait and another $225, a second failure means 14 days, and the fourth and fifth attempts carry 21-day waits, each at the full fee. Three attempts at TCO is $675 in exam fees before any preparation spending.
The credential itself is valid for two years. TCO is the flexible one at recertification: the handbook allows TCO holders to recertify by passing any Tanium exam, which is how most people roll it into the TCA. Tanium makes no exceptions for expired certifications, so the renewal exam fee is a standing every-two-years cost.
Where TCO Attempts Actually Go Wrong
The first failure point is version confusion. Candidates who book in the transition window without checking the candidate portal can end up facing v1 simulations built on an older console interface - Tanium's own guide flags that those items may not match what you see in Tanium today - or studying the v1 blueprint and sitting v2's heavier action-deployment weighting. Confirming which version your appointment delivers is step one of any sane plan.
The second is treating an entry-level label as an easy pass. The published candidate profile expects three to six months of hands-on Tanium time for a reason: the blueprint is dominated by doing, not defining. Querying endpoints with natural language or the question builder, drilling down and merging questions, targeting the right endpoints, deploying and verifying an action, and building a reusable report are console skills, and candidates who only read the course material feel the gap on simulation and practical items.
The third is logistics, not knowledge. The 48-hour reschedule rule, the 15-minute late cutoff, the English-only proctor communication, and the ID rules all forfeit real money when they go wrong - and none of them appear on a blueprint.

How We Think About Exam Security
Every Tanium sitting runs under a live offsite Pearson proctor - on OnVUE or in a center - and every candidate accepts Tanium's Candidate Agreement on exam-content confidentiality. Tanium determines pass and fail through statistical analyses and publishes no threshold, and results land in the candidate portal typically within 24 hours. That is the published environment, and it is why we plan every engagement around the official delivery rules - the published OnVUE room, equipment, and identity requirements or the test-center equivalent - instead of against them.
You will see cheaper offers that promise the world on this exam. Ask them what happens when the proctoring record and the statistical review meet the sitting. Our model only makes money when your pass posts and stays posted, which is exactly the outcome you are paying for.
What we control is the quality, discretion, and privacy of the engagement: an honest feasibility answer before anything starts, a structured execution plan, and a fee that follows the result. Your details stay private, and if your situation makes the service a bad fit, we tell you before you spend anything.
The Payment Model, Stated Plainly
You pay the service fee only after the agreed result posts. Tanium's $225 exam fee, any voucher purchase, and any retake fees are the exam's own costs, separate from the service fee, and we tell you the full picture up front so there are no surprise line items.
We accept the usual range of payment methods and can work around procurement constraints for employer-sponsored sittings - ask in the first message and you will get a straight answer.
What Operations Professionals Say
My employer rolled out Tanium Cloud and made the TCO the team baseline. They confirmed which version my window would deliver, handled the OnVUE sitting at home, and I paid after the pass showed in the candidate portal.
Three years in SOC work but almost no console time on Tanium. The feasibility answer was honest about that gap, the sitting was handled end to end, and the fee came after the result posted.
Needed the TCO done before a platform migration deadline. Scheduling, check-in, the sitting itself - all handled, with the $225 exam fee separate and visible from the first message.
