TDS-C01 Passing Score 2026: Exactly What You Need to Pass

What the TDS-C01 Passing Score Actually Is

If you're preparing for the Salesforce Certified Tableau Desktop Foundations exam (formerly Tableau Desktop Specialist, TDS-C01), the single number that matters most on exam day is the passing score. Salesforce, which administers this credential through Trailhead Academy, sets the passing score at 48% for the English-language exam and 55% for the Japanese-language exam. Those two figures are the only official thresholds candidates need to know - there is no separate "scaled score" system to decode.

The exam itself consists of 40 scored multiple-choice and multiple-select questions, delivered within a 70-minute window. That structure matters because it lets you translate the percentage into a concrete number of questions, which is far more useful when you're pacing yourself during practice tests on our TDS-C01 practice test platform.

Why 48% (Not 55%) Applies to Most Candidates

Most candidates sitting the TDS-C01 exam outside Japan will be held to the 48% passing standard. Doing the arithmetic: 48% of 40 scored questions equals 19.2, which rounds up to 20 questions answered correctly. That's a meaningfully lower bar than many other technical certifications, and it's one reason the exam is often described as approachable for candidates with real hands-on Tableau Desktop experience - a topic covered in more depth in our difficulty guide for the TDS-C01 exam.

The Japanese exam's 55% threshold works out to 22 correct answers out of 40. If you're testing in Japanese, plan your study time with that slightly higher bar in mind, since the margin for error shrinks by roughly two additional correct answers.

How Domain Weighting Affects Your Score

The 40 scored questions aren't distributed evenly across topics. They're allocated according to four exam domains, and understanding this weighting is essential to hitting your passing score efficiently rather than by accident. For a full breakdown of what each domain actually tests, see our complete guide to all four TDS-C01 content areas.

Because Exploring and Analyzing Data represents more than a third of your scored questions, a candidate who is weak in that domain has a much harder path to 48% than one who is weak in Understanding Tableau Concepts. Weight your review accordingly rather than spreading time evenly across all four areas.

Scored vs. Unscored Questions on the Exam

One detail that surprises first-time candidates: the exam includes up to five unscored questions in addition to the 40 scored ones. These unscored items are indistinguishable from scored questions during the test - there's no label telling you which is which. Salesforce uses them to evaluate potential future exam content, and they have zero impact on whether you clear the 48% or 55% passing score.

The practical implication is simple: answer every question as if it counts, because you genuinely cannot tell which five (if any) do not. This is one of several nuances worth internalizing before exam day, alongside the format and timing details covered in our first-attempt study guide.

What the Passing Score Doesn't Tell You

A percentage-based passing score tells you the minimum bar, but it doesn't tell you where you're likely to lose points. Because the exam is closed book and proctored (available both onsite and via online proctoring), you can't compensate for weak domain knowledge by looking things up mid-test. The official exam guide currently tests against Tableau 2022.3, so studying with a newer or older interface can create small but costly mismatches in menu labels or default behaviors.

It's also worth noting that this credential does not require ongoing maintenance once earned - there's no recurring recertification exam tied to future Tableau versions. That makes getting a strong first-attempt result even more valuable, since you won't be revisiting this specific passing threshold again down the road.

Registration, Fees, and Retakes

Understanding the passing score also means understanding what happens if you don't clear it on the first try. Registration for the TDS-C01 exam costs $75 USD (or JPY 10,000 plus applicable tax for the Japanese exam). There is no prerequisite to sit the exam, though Salesforce indicates the target candidate typically has at least three months of hands-on Tableau Desktop experience before attempting it - details worth reviewing in our eligibility and requirements breakdown.

Perhaps the most candidate-friendly detail in the entire program: the retake fee is free. If you fall short of 48% (or 55% for Japanese), you aren't locked out by a costly re-registration fee the way many other certification exams work. That said, "free retake" doesn't mean "unlimited attempts without consequence" - you still lose scheduling time and need to book a new session, so it pays to review our complete pricing breakdown and plan your first attempt seriously rather than treating it as a practice run.

If your first attempt doesn't go as planned, check current testing availability and book your next session using our guide to TDS-C01 testing windows and scheduling so you don't lose momentum between attempts.

Building a Study Plan Around the Threshold

Because 48% is a relatively low bar mathematically, some candidates make the mistake of under-preparing. A smarter approach is to allocate study weeks proportional to domain weight, since Exploring and Analyzing Data alone accounts for more scored questions than any other two domains combined.

Spacing your review this way - weighting time investment to match domain weighting rather than splitting hours evenly - is one of the few generic study techniques that actually maps cleanly onto TDS-C01's specific structure.
