- A00-282 is the SAS exam for Clinical Trials Programming Using SAS 9.4, built for programmers working on clinical study data.
- The exam has 60-70 questions, runs 110 minutes, and requires 68% to pass; the published fee is USD 180.
- Validate Clinical Trial Data Reporting is the heaviest domain at 20%.
- You can sit the exam first, but the credential is awarded only after you hold a qualifying SAS prerequisite.
What A00-282 Actually Is
A00-282 is the exam code for SAS Certified Professional: Clinical Trials Programming Using SAS 9.4, issued by SAS Institute and delivered through Pearson VUE. It validates that a programmer can do the real work of a clinical trials programming team in SAS 9.4: understanding the trial process, working with standardized data structures, preparing data for regulatory submission, transforming and summarizing data, applying statistical procedures, writing macros, producing reports, and validating the output.
That last point deserves emphasis. This is not a general SAS syntax exam. Plenty of candidates assume that strong Base SAS skills will carry them, then discover that a fifth of the exam is about validating clinical trial data reporting, and that the rest assumes you think in terms of datasets, submissions and statistical outputs rather than isolated DATA steps. If you are weighing whether the credential suits your career, our ROI analysis of the A00-282 certification covers that question in depth.
Other pages on this site address the code from different angles, including what A00-282 stands for and the meaning of the A00-282 code. This article is the overview: what the exam is, how it works and what it expects of you.
Specialist vs. Professional: Untangling the Naming
One source of confusion is worth clearing up early. On SAS's credential page, the marketing subheading uses the word "Specialist," but the A00-282 registration block and the certification pathway identify the credential as the Professional credential. This site follows the registration and pathway wording: SAS Certified Professional: Clinical Trials Programming Using SAS 9.4.
If you see "Specialist" attached to this exam in a search result or a recruiter's job posting, you are almost certainly looking at the same exam. Always confirm the exam code, A00-282, when you register, since the code is what appears in your Pearson VUE booking.
Exam Format, Fee and Retake Rules
| Item | A00-282 Detail |
|---|---|
| Questions | 60-70, multiple-choice and short-answer |
| Time allowed | 110 minutes |
| Passing score | 68% |
| Published standard fee | USD 180 |
| Retake policy | Up to five attempts per 12 months, at least 14 days between attempts |
| Expiry | No expiry statement for this exam, so the credential currently does not expire |
| Academic discount | Eligible academic candidates can request a USD 75 voucher before registering (excludes China and India; Japanese students are directed to their local SAS office) |
The mix of multiple-choice and short-answer questions matters for preparation. Short-answer items ask you to supply a value, a keyword, or a piece of code rather than recognize the right option from a list, so passive reading is a weak strategy. You need to be able to write and predict SAS code without prompts. For a closer look at the scoring threshold, see our guide to the A00-282 passing score, and for a full breakdown of fees and discounts, read the A00-282 certification cost guide.
The Prerequisite That Catches Candidates Out
Here is where A00-282 differs from many certification exams. SAS separates taking the exam from receiving the credential. You may take A00-282 before you hold any prerequisite certification, but the credential itself is awarded only once you meet the requirement.
The qualifying prerequisites are:
- SAS Certified Specialist: Base Programming Using SAS 9.4, or
- SAS Certified Professional: Advanced Programming Using SAS 9.4
The older A00-211 and A00-212 credentials do not satisfy this prerequisite. SAS also lists recommended training or equivalent experience and suggests at least six months working as a clinical trials programmer using SAS. SAS clarified the prerequisite handling in a community post titled "A00-282 without prerequisite certification" (29 August 2024), which also notes the 2022 update to the Professional credential.
The Nine Domains and What They Test
The official exam content guide divides A00-282 into nine weighted domains totaling 100%. The weights tell you where to spend your time, and they are lopsided in a useful way.
| Domain | Weight |
|---|---|
| 1. Clinical Trials Process | 5% |
| 2. Clinical Trials Data Structures | 10% |
| 3. Regulatory Submissions | 5% |
| 4. Manage Clinical Trials Data | 5% |
| 5. Transform or Summarize Clinical Trials Data | 15% |
| 6. Apply Statistical Procedures for Clinical Trials | 15% |
| 7. Macro Programming for Clinical Trials | 15% |
| 8. Report Clinical Trials Results | 10% |
| 9. Validate Clinical Trial Data Reporting | 20% |
Four domains (validation, transformation, statistical procedures and macros) account for 65% of the exam. The three smallest conceptual domains (process, regulatory submissions, data management) add up to just 15%. Our complete guide to all nine A00-282 content areas goes domain by domain; the sections below give the working summary.
Domain 9: Validate Clinical Trial Data Reporting (20%)
The single largest slice of the exam. Validation in clinical programming usually means confirming that a dataset or table is correct, often by independently reproducing it and comparing.
- Comparing datasets and interpreting the results of comparison procedures
- Reading logs for errors, warnings and notes that signal data problems
- Checking derived values against specifications
- Recognizing how independent programming supports quality control
Domain 5: Transform or Summarize Clinical Trials Data (15%)
This is the hands-on data manipulation domain, applied to trial data.
- Combining, restructuring and deriving variables across datasets
- Transposing between wide and long layouts
- Summarizing data for analysis and reporting
Domain 6: Apply Statistical Procedures for Clinical Trials (15%)
Not a statistics theory exam, but you must know which SAS procedure produces which output and how to read it.
- Selecting appropriate procedures for common trial analyses
- Interpreting procedure output and options
- Understanding how analysis datasets feed these procedures
Domain 7: Macro Programming for Clinical Trials (15%)
Clinical programming relies on reusable code across studies, so macros are central.
- Creating and calling macros with parameters
- Using macro variables and the macro language to generate code
- Predicting what resolved macro code will look like
Domain 2: Clinical Trials Data Structures (10%) and Domain 8: Report Clinical Trials Results (10%)
Domain 2 covers how trial data is organized into standard structures, while Domain 8 covers turning analysis results into listings, tables and figures.
- Understanding the purpose and layout of standardized clinical datasets
- Producing reports and output for clinical review
Domains 1, 3 and 4 (the clinical process, regulatory submissions and data management) are each 5%. They are smaller, but they supply the context that makes the other questions make sense, and they are often the easiest points to win with focused reading.
Topics Worth Mastering Before Exam Day
Because many questions ask you to predict outcomes or supply short answers, certain skills pay off disproportionately:
- Reading a SAS log critically. Validation questions often hinge on spotting what a log is telling you.
- Dataset comparison. Know what a comparison reports when values, variables or observations differ.
- Macro resolution. Be able to trace how macro variables resolve and how quoting and scope affect results.
- Restructuring data. Wide-to-long and long-to-wide transformations appear constantly in trial data work.
- Matching procedure to purpose. You should know, without looking it up, which procedure suits which kind of summary or analysis.
For a realistic sense of how demanding these are, see how hard the A00-282 exam really is. If you want a compact reference to revisit in the final days, the A00-282 cheat sheet condenses the must-know facts.
Key Takeaway
Do not treat validation as an afterthought. At 20%, Domain 9 outweighs any other single domain, and it rewards candidates who practice reading logs and comparison output, not just writing code.
Test Center or Remote: How Delivery Works
A00-282 is delivered through Pearson VUE, either at a test center or remotely via Pearson OnVUE with online proctoring. If you choose remote delivery, expect these requirements:
- A successful system check on the computer you will use
- A photo ID that matches the name on your registration
- A clear, private testing space
- A digital whiteboard for scratch work, since physical writing materials are not allowed
That digital whiteboard detail is worth rehearsing. If you normally work through macro resolution or data step logic on paper, practice doing it in a plain on-screen tool before exam day so the format does not slow you down. Details on scheduling windows are in our A00-282 exam dates guide.
Who Uses This Credential
Clinical trials programming sits inside pharmaceutical companies, biotechnology firms, and contract research organizations (CROs), plus the consultancies and staffing firms that supply programmers to them. Typical roles include clinical SAS programmer, statistical programmer, and programmer-analyst on biostatistics teams. The credential signals that you can handle SAS in the context of regulated clinical work rather than only general business analytics.
SAS's own guidance recommends at least six months as a clinical trials programmer using SAS, which tells you who the exam is aimed at: practitioners with some exposure, or career changers who have built equivalent skills through training and practice. For role-level detail, see A00-282 jobs, and for compensation context, our A00-282 salary guide discusses earnings qualitatively and by role.
Sequencing Your Preparation by Domain Weight
Rather than study in the order the domains are listed, order your preparation by dependency and weight. This is one reasonable ordering for a six-week plan, built around A00-282's structure:
Context and data structures
- Clinical trials process and regulatory submissions (Domains 1 and 3)
- Standard clinical data structures (Domain 2)
Core programming domains
- Transform and summarize data (Domain 5)
- Macro programming (Domain 7)
Statistics and reporting
- Statistical procedures (Domain 6)
- Reporting results (Domain 8)
Validation and data management
- Validate clinical trial data reporting (Domain 9)
- Manage clinical trials data (Domain 4)
Timed practice and review
- Full-length timed sets against the 110-minute limit
- Targeted review of weak domains
Validation sits late because it builds on everything before it: you cannot verify a report you do not understand how to create. For a more detailed plan, see the A00-282 study guide, and when you are ready to test yourself under realistic conditions, take a timed attempt on our A00-282 practice test site.
Retired Exams and Related Credentials
You may encounter references to A00-280 and A00-281 while researching. These are separate, retired exams. SAS's bridge page states that their availability ended after 31 January 2023, though credentials already awarded remain valid. They are not substitutes for A00-282, and they are distinct from the A00-211 and A00-212 credentials that, as noted above, do not satisfy the A00-282 prerequisite.
If you hold an older credential and are unsure where you stand, check the SAS certification pathway and consult the A00-282 certification overview. For a plain-language explanation of the code itself, you can also read what the A00-282 certification is.
