- A00-282 is SAS's Clinical Trials Programming Using SAS 9.4 exam, administered through Pearson VUE.
- The exam has 60-70 questions, runs 110 minutes, requires 68% to pass, and costs USD 180.
- Validate Clinical Trial Data Reporting is the heaviest domain at 20% of the exam.
- You can sit the exam first, but the credential requires Base Programming 9.4 or Advanced Programming 9.4.
What the A00-282 Credential 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 is a role-specific credential: rather than testing SAS in the abstract, it tests whether you can use SAS 9.4 to do the work of a clinical trials programmer, from reading data structures to producing validated tables, listings and figures for regulatory review.
The distinction matters because many SAS credentials measure general language fluency. A00-282 measures applied fluency in a regulated setting. Questions assume you understand how a clinical trial generates data, how that data is organized into standard structures, and how programmers transform, analyze, report and independently verify results. If you are new to the exam, this page gives the overview; the A00-282 Certification and What Is A00-282? pages cover the same ground from other angles.
For a plain-language breakdown of the code itself, see What Does A00-282 Stand For? The short version: it is simply SAS's internal identifier for this one exam, and the same acronym belongs to unrelated credentials from other organizations. Everything on this site refers only to the SAS clinical trials exam.
Specialist or Professional? Untangling the Naming
One source of confusion deserves a direct explanation. SAS's credential page carries a marketing subheading that uses the word "Specialist," yet the A00-282 registration block and the certification pathway both identify the credential as SAS Certified Professional: Clinical Trials Programming Using SAS 9.4. This site follows the registration and pathway wording, because those are the parts that govern what you actually register for and what you are awarded.
SAS also noted in a 2024 clarification on its community forum that the Professional credential was updated in 2022. In practice, that means older study material written before the update can describe a different structure, so check the date on anything you rely on.
The Prerequisite Credential Rule
This is the single most misunderstood part of A00-282, and it is worth reading carefully. The exam and the credential are decoupled:
- You may take the A00-282 exam first. Passing the exam does not depend on already holding another credential.
- You receive the credential only after meeting its prerequisite. That prerequisite is either 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 the requirement. Only the SAS 9.4 versions count.
SAS additionally lists recommended training or equivalent experience, and at least six months working as a clinical trials programmer using SAS, as the background it expects. Those are recommendations rather than gates to registration, but they signal the level the questions are pitched at. For the full eligibility picture, read A00-282 Requirements: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Plan your sequence deliberately. If you do not yet hold Base Programming 9.4 or Advanced Programming 9.4, you can still sit A00-282, but you will not be awarded the credential until you add one of those two. Many candidates simply earn Base first to avoid an awkward gap.
Exam Format, Fee and Delivery
The published exam facts are compact and worth memorizing, because they shape how you pace yourself and budget.
| Item | A00-282 Detail |
|---|---|
| Questions | 60-70, multiple-choice and short-answer |
| Time allowed | 110 minutes |
| Passing score | 68% |
| Standard fee | USD 180 |
| Retake policy | Up to five attempts per 12 months, at least 14 days apart |
| Expiry | No expiry is stated for this exam, so the credential currently does not expire |
| Academic discount | USD 75 voucher for eligible academic candidates, requested before registration |
Question style
The mix of multiple-choice and short-answer questions is unusual for a programming exam. Expect to read SAS code and predict its output, spot the error in a snippet, choose the correct option or statement, and in short-answer items type a specific response rather than recognizing it from a list. Typing an answer means you cannot rely on recognition alone; you need to recall exact syntax and keyword spelling.
Test center or remote delivery
You can test at a Pearson VUE center or through remotely proctored OnVUE. Online candidates must pass a system check, present matching photo ID, and have a clear testing space. A digital whiteboard replaces physical writing materials, so practice working out code logic on a screen rather than on paper. Timing and scheduling specifics are covered in A00-282 Exam Dates: Testing Windows, Deadlines & Scheduling.

The Nine Weighted Domains
SAS publishes the exam as nine weighted sections that total 100%. The weights tell you where the points are, which is the most useful planning information you have.
| Domain | Weight |
|---|---|
| Clinical Trials Process | 5% |
| Clinical Trials Data Structures | 10% |
| Regulatory Submissions | 5% |
| Manage Clinical Trials Data | 5% |
| Transform or Summarize Clinical Trials Data | 15% |
| Apply Statistical Procedures for Clinical Trials | 15% |
| Macro Programming for Clinical Trials | 15% |
| Report Clinical Trials Results | 10% |
| Validate Clinical Trial Data Reporting | 20% |
Three observations stand out. First, Validate Clinical Trial Data Reporting is the largest single domain at 20%, larger than any of the three 15% domains. Second, the three 15% domains (transformation, statistical procedures and macro programming) together account for 45%, so the hands-on SAS programming core is nearly half the exam. Third, the process, regulatory and data-management domains are only 5% each, so they are worth covering efficiently rather than exhaustively. A domain-by-domain walkthrough lives in A00-282 Exam Domains: Complete Guide to All 9 Content Areas.
Concrete Skills Candidates Must Master
The domain names are broad, so here is what they translate to in practice.
Validate Clinical Trial Data Reporting (20%)
Validation is the heart of regulated programming. A second programmer independently reproduces results and the two outputs are compared, so you must know how to demonstrate that your work is correct.
- Comparing datasets and interpreting the output of PROC COMPARE, including differences in values, attributes and observations
- Reading logs for errors, warnings and notes that signal real problems, such as uninitialized variables or unintended merge behavior
- Recognizing why two supposedly identical outputs diverge
Transform or Summarize Clinical Trials Data (15%)
Raw collected data rarely arrives in analysis-ready shape, so you reshape and derive.
- Merging, concatenating and restructuring datasets, including transposing between wide and long layouts
- Deriving variables such as flags, study days and baseline values
- Summarizing with PROC MEANS and PROC FREQ, and understanding how missing values affect the results
Apply Statistical Procedures for Clinical Trials (15%)
You are not expected to be a biostatistician, but you must run and read the standard procedures correctly.
- Selecting and running appropriate procedures for continuous and categorical outcomes
- Interpreting output to confirm the right comparison was performed
- Knowing which output datasets to capture for downstream reporting
Macro Programming for Clinical Trials (15%)
Clinical programs are repetitive across studies, so macros do heavy lifting.
- Defining macro variables and macros with parameters, and understanding scope
- Using conditional and iterative macro logic, and resolving macro references correctly
- Tracing what a macro generates, which is a common code-reading question
Clinical Trials Data Structures (10%)
Standardized structures make submissions consistent. Expect questions on how data is organized into standard domains and how variables are named and typed, along with the relationship between collected and analysis data.
Report Clinical Trials Results (10%)
This domain covers producing the outputs reviewers actually read.
- Building tables and listings with PROC REPORT and related procedures
- Controlling titles, footnotes, formats and page layout with ODS
The remaining three domains (Clinical Trials Process, Regulatory Submissions and Manage Clinical Trials Data) are conceptual and lighter. They ask whether you understand the phases of a trial, the purpose and structure of a regulatory submission, and how data is managed and kept consistent. Treat them as vocabulary and context rather than coding drills.
Who Should Pursue It and Who Hires for It
The credential is aimed at people who program, or intend to program, in the clinical research setting. Typical roles include statistical programmers and clinical SAS programmers, usually employed by pharmaceutical and biotechnology sponsors, contract research organizations (CROs), and the consultancies that supply programming resources to them. Because the exam mirrors day-to-day tasks in those environments, it works as a signal that a candidate understands both SAS and the regulated context around it.
It is especially useful if you are moving into clinical programming from another SAS background, or if you are early in your career and want an external benchmark alongside your experience. Whether it is worth the effort for your situation depends on your target employers; the Is the A00-282 Certification Worth It? ROI analysis weighs that, and A00-282 Jobs looks at the roles it maps to. For compensation context, see the A00-282 Salary Guide.
A00-280 and A00-281: Retired Predecessors
You may encounter references to A00-280 and A00-281 in older forum posts or study notes. These are separate, retired exams. SAS's bridge page states that their availability ended after 31 January 2023, while credentials already awarded through them remain valid. They are not alternate versions of A00-282, and preparing from material written for them risks studying the wrong blueprint. If a resource centers on those codes, treat it with caution and confirm it matches the current nine-domain structure above.
Sequencing Your Preparation Around the Weights
Because the weights are published, you can allocate time proportionally instead of guessing. A sensible order puts the foundations first, the heavy programming core in the middle, and validation last so it consolidates everything.
Context and structures
- Cover Clinical Trials Process, Regulatory Submissions and Manage Clinical Trials Data (5% each) quickly
- Spend real time on Clinical Trials Data Structures (10%), since later domains build on it
The 15% programming core
- Transformation, then statistical procedures, then macro programming
- Write code daily; reading answers will not build recall for short-answer items
Reporting and validation
- Practice Report Clinical Trials Results (10%)
- Finish with Validate Clinical Trial Data Reporting (20%), reproducing earlier work independently and comparing it
Adjust the length to your experience; someone with a year of clinical programming may compress this considerably. Full planning detail is in the A00-282 Study Guide, and a condensed reference is available in the A00-282 Cheat Sheet. To gauge how demanding the material is before committing, read How Hard Is the A00-282 Exam? and A00-282 Pass Rate: What the Data Shows.
Key Takeaway
Do timed practice questions that mix code reading with typed short answers. The format rewards exact recall, so test yourself on realistic items using the A00-282 practice tests and review every miss against the nine domains above.
If you want structured courses rather than self-study, A00-282 Training covers the options. When you are ready to measure your readiness, the full set of questions on the A00-282 Exam Prep practice test site mirrors the domain weighting so your practice time matches the real exam.
