- The DSP-210 passing standard is 72% or 69%, depending on which equated exam form you receive.
- Only 75 of the 90 questions are scored; 15 are unscored, and you cannot tell which.
- Performing exploratory data analysis carries the largest weight at 25-36%, so it deserves the most prep time.
- The 72%/69% figure is a cut score, not a pass rate; the two should never be confused.
What the Passing Standard Actually Is
If you are preparing for the Certified Data Science Practitioner credential from CertNexus, the first number you will want to pin down is the passing standard. For the DSP-210 exam, the passing standard is 72% or 69%, depending on the equated form you are assigned. That is the threshold your performance on the scored items must meet or exceed.
It is worth being precise about what this number represents. It is a cut score applied to your result, not a statistic describing how many candidates succeed. Plenty of candidates conflate the two, and the confusion leads to bad planning. If you want to understand how often candidates actually succeed and why published figures should be treated cautiously, read our breakdown in CDSP Pass Rate 2026: What the Data Shows.
Why 72% and 69% Both Appear
Seeing two different passing percentages for a single exam looks odd at first, but it reflects a common practice in certification testing. When a credential has multiple versions of the exam in circulation, the versions are statistically equated so that a pass on one form represents the same level of competence as a pass on another. Small differences in how hard each form turns out to be are balanced by adjusting the required percentage.
In practical terms for CDSP candidates:
- A slightly harder form may carry the lower threshold of 69%.
- A slightly easier form may carry the higher threshold of 72%.
- You will not know in advance which form you will receive, so plan to the higher figure.
The sensible approach is to treat 72% as your working target in every practice session. If you consistently perform at or above that level across all domains, a 69% form becomes a comfortable margin rather than a hope.
75 Scored Questions, 15 Unscored
The DSP-210 delivers 90 total questions, but only 75 are scored. The remaining 15 are unscored items, typically used to evaluate new questions for future exam versions. They are indistinguishable from scored items on screen.
This has two direct consequences for how you take the exam:
- Treat every question as if it counts. You cannot identify the unscored items, so skipping effort on a question you believe is "experimental" is a gamble with no upside.
- Do not panic over a handful of unfamiliar items. Some questions that feel strange or out of scope may simply be unscored pilot items. One difficult question is not evidence that you are failing.
Because the passing standard applies to the 75 scored questions, the percentage translates to roughly 54 correct answers at 72% and roughly 52 at 69% (calculated from the 75 scored items). Treat those as approximations for planning rather than official targets, since the exact scoring method is determined by the issuer and the form.
How Domain Weights Shape Your Score
The CDSP blueprint publishes domain weights as ranges rather than fixed percentages. That means the exact number of questions per domain can vary from form to form. Here is the structure candidates should plan around:
| Domain | Official Weight |
|---|---|
| Domain 1: Defining the need to be addressed through the application of data science | 7-9% |
| Domain 2: Extracting, Transforming, and Loading Data | 17-25% |
| Domain 3: Performing exploratory data analysis | 25-36% |
| Domain 4: Building models | 19-27% |
| Domain 5: Testing models | 4-7% |
| Domain 6: Operationalizing the pipeline | 5-8% |
| Domain 7: Communicating findings | 4-7% |
Three domains dominate: exploratory data analysis, building models, and ETL. Together their ranges account for the majority of the exam. A candidate who is strong in those three and merely adequate elsewhere is in a far better position than one who spreads effort evenly. For a deeper walkthrough of each area, see CDSP Exam Domains 2026: Complete Guide to All 7 Content Areas.
Why Exploratory Data Analysis Matters Most
At 25-36%, Performing exploratory data analysis is the single heaviest domain. If your score is going to be made or broken anywhere, it is here. Candidates should be ready to reason about data distributions, missing values, outliers, feature relationships, visualization choices, and summary statistics, and to interpret what an analysis output implies rather than just recognize terminology.
The Small Domains Still Count
Domains 1, 5, 6 and 7 carry smaller weights, but at 72% you cannot afford to concede them entirely. Questions in Testing models, Operationalizing the pipeline, and Communicating findings often test judgment, such as choosing an appropriate evaluation approach or framing results for a non-technical audience. These are areas where many technically strong candidates drop easy points simply because they under-prepared.
Building a Score Strategy Around the Blueprint
Since the passing standard is a single overall threshold rather than a per-domain requirement, you have flexibility in how you reach it. Based on what the official information provides, the exam is scored against the overall result on the scored items, so a weak domain can be offset by strength elsewhere. That said, relying on offsets is risky when weights are ranges that shift between forms.
A Practical Target Profile
Aim for a profile that clears the higher 72% line even if one area underperforms.
- Exploratory data analysis: aim for your strongest performance here.
- Building models and ETL: aim for solid, consistent accuracy.
- Testing models, pipeline operations, communication, and problem definition: aim to avoid giving away easy points.
One useful habit is to score your practice results by domain, not just overall. A single overall number can hide a domain where you are well below the line. If you want a structured plan for converting this into a study schedule, our CDSP Study Guide 2026: How to Pass on Your First Attempt maps the preparation process step by step.
Calibrating Against the Difficulty Question
Many candidates ask whether 72% is a demanding standard. It is moderate in absolute terms, but the difficulty comes from breadth: you need working fluency in programming, statistics, and data handling across the full pipeline from problem definition to communicating results. For an honest take on how that breadth feels in practice, see How Hard Is the CDSP Exam? Complete Difficulty Guide 2026.
Format Details That Are Still Unclear
Part of being well prepared is knowing what is confirmed and what is not. Several details about the DSP-210 should be treated with caution because the available official sources are not fully consistent.
- Question types: The live exam page describes multiple choice and multiple response, while blueprint version 1.6 describes multiple choice with single response. This discrepancy needs clarification from the issuer. Prepare for both: practice choosing a single best answer and also selecting several correct options.
- Calculator use: Whether a personal calculator is permitted has not been verified. Do not assume you can bring one, and practice doing estimation and reasoning without relying on a calculator.
- Adaptive delivery: Whether the exam is adaptive has not been verified either. Do not build a strategy that depends on assumptions about question order or difficulty adjustment.
The exam is closed-book and proctored, so you will not have reference materials. This reinforces the need to internalize key concepts instead of planning to look things up. Because multiple response items, if present, can be harder to score well on than single-answer items, practicing both styles protects you regardless of how the clarification resolves.
Key Takeaway
Prepare for the uncertainty rather than waiting on it. Practice both single-answer and select-all-that-apply question styles, and check the official CertNexus and Pearson VUE pages shortly before exam day for any updates to format rules.
Fees, Delivery and Scheduling
The DSP-210 is delivered by Pearson VUE, either at a test center or through OnVUE online proctoring. The core pricing, per the official information, is:
| Item | Price (USD) |
|---|---|
| Exam voucher | $367.50 |
| Optional digital guide | $103.95 |
| Guide plus voucher bundle | $424.31 |
Since a failed attempt means paying for another voucher, there is a real financial argument for being comfortably above 72% in practice before you book. For a full look at what total preparation and certification spending looks like, see CDSP Certification Cost 2026: Complete Pricing Breakdown.
Time Allocation on Exam Day
Your appointment is two hours, which includes a 5-minute agreement and a 5-minute tutorial. That implies roughly 110 minutes of actual testing time for 90 questions, or a little over one minute per question. Practice pacing accordingly: if a question is consuming far more than a minute, flag it, make your best choice, and move on. Because 15 questions are unscored and unidentifiable, over-investing in any one item is a poor trade.
There are no formal prerequisites or mandatory training for the exam, though programming, statistics, and data-handling competence are recommended. Details are covered in CDSP Requirements 2026: Eligibility, Prerequisites & How to Qualify. When you are ready to test your readiness against realistic questions, you can try the full set of practice questions on our CDSP practice test platform.
Allocating Study Weeks by Domain
Rather than a generic schedule, tie your calendar to the weights. The ordering below front-loads the heaviest and most foundational material so that later weeks can reinforce rather than introduce it. This is one reasonable approach, not an official recommendation.
ETL and Exploratory Data Analysis
- Data extraction, cleaning, transformation, and loading workflows
- Distributions, missing data, outliers, and feature relationships
- Visualization choices and what each reveals
Building and Testing Models
- Model selection, feature engineering, and training workflow
- Evaluation approaches, overfitting, and validation logic
Problem Definition, Pipelines, Communication
- Framing a business need as a data science problem
- Operationalizing a pipeline
- Presenting findings to non-technical stakeholders
Timed Practice at the 72% Line
- Full-length timed sets at roughly 110-minute pacing
- Domain-level score review and targeted repair

A note on version history that matters if you are using older study materials: DSP-210 launched in September 2024, blueprint v1.6 was modified on February 3, 2025, and the predecessor exam DSP-110 was retired on February 28, 2025. Make sure any practice resources you use align with the current DSP-210 blueprint rather than the retired exam.
Frequently Asked Questions
The DSP-210 passing standard is 72% or 69%, depending on the equated exam form you receive. Since you cannot know which form you will get, aim for 72% in all your practice.
No. The percentage is a passing standard, meaning the performance level you must reach. It does not describe how many candidates pass. These are different concepts and should not be mixed up.
The exam has 90 total questions, of which 75 are scored and 15 are unscored. The unscored items are not identified, so you should answer every question with full effort.
The appointment is two hours, including a 5-minute agreement and a 5-minute tutorial. That leaves roughly 110 minutes of testing time, or a little over one minute per question.
Performing exploratory data analysis is the largest, at 25-36% of the exam. Building models (19-27%) and Extracting, Transforming, and Loading Data (17-25%) follow, so these three deserve the bulk of your preparation.
Understanding the passing standard is only the first step. To see how your readiness measures up against the 72% line, work through timed sets on the CDSP Exam Prep practice platform, and pair them with the structured approach in our CDSP study guide to turn the numbers above into a concrete plan.
