What This Certification Actually Certifies
A00-282 is the exam code for SAS Certified Professional: Clinical Trials Programming Using SAS 9.4, issued by SAS Institute and administered through Pearson VUE. It targets programmers who turn raw clinical trial data into the analysis datasets, tables, listings and figures that support regulatory submissions. If you are new to the code itself, the explainers on what A00-282 is and what A00-282 stands for cover the basics; this article focuses on how the credential works in practice.
The exam is not a general SAS test. It assumes you already write competent DATA step and PROC code and asks you to apply that skill inside the clinical research context: CDISC-style data structures, regulatory expectations, statistical procedures used in trial analysis, reusable macro code, and independent validation of results. That context is what separates it from Base Programming, which is a prerequisite rather than a substitute.
Specialist or Professional? Clearing Up the Naming
One quirk causes confusion. SAS's credential page carries a marketing subheading that uses the word "Specialist," yet the A00-282 registration block and the certification pathway identify the credential as the Professional level. This site follows the registration and pathway wording, so you will see "SAS Certified Professional: Clinical Trials Programming Using SAS 9.4" throughout.
Practically, this means you should always confirm the exam code (A00-282) when you register, rather than relying on how a job posting or résumé happens to label the credential. The code is the unambiguous identifier. For more on how the code is read, see A00-282 meaning.
The Prerequisite Rule That Trips Candidates Up
SAS separates taking the exam from being awarded the credential. You can sit A00-282 before you hold the prerequisite, but the credential is only awarded once you have earned one of the following:
- SAS Certified Specialist: Base Programming Using SAS 9.4, or
- SAS Certified Professional: Advanced Programming Using SAS 9.4
SAS also lists recommended training or equivalent experience, and suggests at least six months working as a clinical trials programmer using SAS. That recommendation is not enforced at registration, but it is a realistic indicator of the knowledge level the questions assume. The full eligibility picture is covered in A00-282 requirements.
Exam Format, Fee and Attempt Policy
| Item | Detail |
|---|---|
| Exam code | A00-282 |
| Questions | 60-70 multiple-choice and short-answer |
| Time allowed | 110 minutes |
| Passing score | 68% |
| Published standard fee | USD 180 |
| Academic voucher | USD 75 on request, before registration |
| Retake policy | Five attempts per 12 months, at least 14 days apart |
| Expiry | No expiry statement in the exam details, so the credential currently does not expire |
The mix of multiple-choice and short-answer questions matters. Short-answer items reward candidates who can produce or complete syntax rather than recognize it, so passive reading of documentation is a weak preparation strategy. Expect to interpret code, predict output, and fill in missing pieces.
Academic pricing
Eligible academic candidates can request a USD 75 voucher before registering. The discount excludes China and India, and Japanese students are directed to their local SAS office. Request the voucher first; it cannot be applied retroactively to a fee already paid. A fuller cost walkthrough, including retake math, is in A00-282 certification cost.
What the passing score means
With 60-70 questions, 68% translates to a specific number of correct answers that varies with the form you receive. The detail is unpacked in A00-282 passing score, and the broader difficulty picture is in how hard the A00-282 exam is.
The Nine Domains and Where the Points Are
SAS publishes nine weighted objective sections totaling 100%. The distribution is more balanced than many certification exams, but one domain stands clearly above the rest.
| 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% |
For a domain-by-domain treatment, see the complete guide to all nine A00-282 content areas.
Hands-On Topics You Must Be Able to Code
Validate Clinical Trial Data Reporting (20%)
The single largest domain, and the one that most reflects real-world clinical programming. Validation in this setting means confirming that your outputs are correct, often through independent reproduction.
- Compare datasets with PROC COMPARE and interpret its report, including differences in values, attributes and observation counts
- Read and diagnose SAS logs for errors, warnings and unexpected notes
- Reason about why two supposedly equivalent programs produce different results
- Check derived variables against specification logic
Transform or Summarize Clinical Trials Data (15%)
Moving from collected data to analysis-ready data.
- Merge, concatenate, and transpose datasets with correct handling of keys and by-groups
- Derive variables such as baseline values, study days and flags
- Summarize with PROC MEANS, PROC FREQ and PROC SUMMARY
- Work with dates, formats and character-to-numeric conversions
Apply Statistical Procedures for Clinical Trials (15%)
Choosing and interpreting the right procedure for a trial question.
- Understand which procedure fits a continuous, binary or time-to-event outcome
- Read procedure output and identify the statistic being asked about
- Recognize the role of treatment groups, covariates and stratification
Macro Programming for Clinical Trials (15%)
Clinical programs are repetitive by nature, so macro fluency is expected.
- Define macro variables and parameterized macros
- Control flow with conditional logic and iterative processing
- Predict how the macro processor resolves references before code executes
- Debug macro code using system options
Clinical Trials Data Structures (10%) and Report Clinical Trials Results (10%)
These two domains cover the standardized shapes data takes and the outputs you deliver.
- Recognize how clinical data is organized into standardized domains and analysis structures
- Produce listings and summary tables using reporting procedures
- Control output formatting, titles, footnotes and page layout
Test Center or OnVUE: How Delivery Works
You can take A00-282 at a Pearson VUE test center or through remotely proctored Pearson OnVUE. Online candidates should prepare for the following:
- A successful system check before exam day
- A photo ID whose name matches your registration
- A clear, private testing space
- A digital whiteboard in place of physical writing materials
The last point deserves attention. Because short-answer questions and code tracing often benefit from scratch work, practice working through code on a digital whiteboard rather than paper. For scheduling windows and booking mechanics, see A00-282 exam dates.
A Domain-Weighted Preparation Order
Rather than studying in the order SAS lists the domains, sequence your effort by weight and dependency. This is the one place for a timeline, built around the exam's own structure; the longer methodology lives in the A00-282 study guide.
Data work and structures
- Domain 5 transformation and summarization, because everything downstream depends on it
- Domain 2 data structures, so your datasets match what the questions assume
Statistics and macros
- Domain 6 procedures and output interpretation
- Domain 7 macro programming with hands-on debugging
Validation and reporting
- Domain 9, the 20% domain, with PROC COMPARE and log reading
- Domain 8 report production
Process domains and full practice
- Quick passes through Domains 1, 3 and 4
- Timed practice sets under 110-minute conditions
Taking timed sets from the A00-282 practice test site late in the schedule exposes pacing problems: 110 minutes for up to 70 questions leaves roughly a minute and a half per item, which is tight if you linger on code-tracing questions.
Who Hires Clinical Trials Programmers
The credential maps to roles in the organizations that run and analyze clinical studies. Typical employers include:
- Pharmaceutical and biotechnology companies building submission datasets and reports in-house
- Contract research organizations (CROs) that provide programming and biostatistics services to sponsors
- Medical device companies running regulated studies
- Academic medical centers and research institutes conducting sponsored or investigator-led trials
Job titles vary, but you will commonly see statistical programmer, clinical SAS programmer, and clinical data analyst. The credential signals that you understand the clinical context and not just the language. For market detail, see A00-282 jobs, and for earnings context, the A00-282 salary guide. Whether the investment pays off for your situation is analyzed in whether A00-282 is worth it.
Key Takeaway
Treat A00-282 as a clinical-context credential layered on a SAS foundation. Employers screening for regulated-environment experience will read it as evidence you know why validation, traceability and data standards matter, not only how to write syntax.
A00-280 and A00-281: The Retired Predecessors
You may encounter references to A00-280 and A00-281 in older forums or job descriptions. These are separate retired exams. SAS's bridge page states that their availability ended after 31 January 2023, while credentials already awarded under them remain valid. If you earned one of those earlier credentials, it still stands; if you are starting now, A00-282 is the path to pursue. Do not mix study materials written for the retired exams with the current objectives without checking them against the nine domains above.
Frequently Asked Questions
Yes. You may sit the exam first, but SAS awards the credential only after you hold 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.
The exam contains 60-70 multiple-choice and short-answer questions with a 110-minute time limit. The passing score is 68%, and the published standard fee is USD 180.
SAS's FAQ allows five attempts per 12 months, with at least 14 days between attempts. Use the gap to review the domains where you were weakest rather than simply rebooking.
Applying SAS's published expiry rule, the exam details contain no expiry statement, so the credential currently does not expire. Policies can change, so confirm on SAS's site when you earn it.
Validate Clinical Trial Data Reporting at 20%, followed by the three 15% domains: transformation and summarization, statistical procedures, and macro programming. Together these four domains make up 65% of the exam. For a one-page recap, see the A00-282 cheat sheet and the pass rate analysis.
