What This Cheat Sheet Covers (and Which Exam It Targets)
This page condenses the facts that matter most for the Certified Pega Senior System Architect exam into one scannable review. On this site, "CSSA" is the retained abbreviation for that Pega credential (the formal name carries the PCSSA label). If you are still orienting yourself, our explainers on what CSSA certification is and what CSSA stands for cover the basics before you dive into the details below.
One scoping point deserves emphasis. This cheat sheet is built around the Pega Platform '25 exam, code PEGACPSSA25V1. Pega also lists an earlier exam for Platform '24.2 that uses a different, eight-domain outline. Do not blend the two outlines in your notes, and do not confuse this exam with the System Architect or Lead System Architect examinations, which test different levels of responsibility. Always confirm your target version on Pega Academy before you register.

| Item | What to Remember |
|---|---|
| Issuer | Pegasystems (Pega) |
| Exam code | PEGACPSSA25V1 (Pega Platform '25) |
| Questions | 60 |
| Time | 90 minutes |
| Passing score | 70% |
| Languages | English and Japanese |
| Format | Closed book |
| Delivery | Pearson VUE test centers or OnVUE remote proctoring |

Two small timing details trip people up. First, accepting the NDA is mandatory, and under Pega's general guidance that step is included in your allotted examination time, so do not assume the 90-minute clock starts only after you click through it. Second, candidates registered in Pearson VUE from an eligible non-native-English-speaking country who take the English exam automatically receive 30 additional minutes. That extension appears in the registration confirmation, so check yours rather than assuming.
For a deeper look at the numbers behind passing, see our breakdown of the CSSA passing score. On 60 questions, a 70% threshold works out to needing roughly 42 correct responses, though the exact scoring treatment of multiple-response items is not spelled out in the sources reviewed, so do not rely on a precise raw-score target.
Domain Weights: Where the Points Live
The six official domains and their weights are the backbone of any efficient review. These are Pega's published exam objectives, not an allocation derived from a training course.
| Domain | Weight |
|---|---|
| Application Development | 30% |
| Case Management | 20% |
| Data and Integration | 20% |
| System Administration | 15% |
| Security | 10% |
| User Experience | 5% |
The pattern is clear: the first three domains account for 70% of the exam. A candidate who is strong in Application Development, Case Management, and Data and Integration has a large cushion even if User Experience feels thin. That said, 5% of 60 questions is still a handful of items, and a weak spot in any domain adds up when the margin is tight. Our complete guide to all six CSSA content areas walks through each domain in more depth.
Application Development: Must-Know Facts
Domain 1: Application Development (30%)
The largest domain tests whether you can structure and reuse rules the way a senior architect would, rather than simply build a single feature.
- Application layering and how rulesets and class structure support reuse across implementations
- Inheritance and specialization: choosing where a rule should live so it can be reused or overridden appropriately
- Rule resolution and how the platform selects the applicable rule version among candidates
- Reusable components, templates, and building blocks versus one-off configuration
- Decisioning and declarative logic: when to use declarative rules versus procedural logic
- Debugging and tracing rule behavior when an outcome is not what you expected
Because this domain is weighted at 30%, expect scenario questions that describe a design problem and ask which approach best supports reuse, maintainability, or performance. The distinction between a senior architect and a system architect shows up here: the senior exam rewards judgment about structure, not just knowing where a setting is.
Case Management: Must-Know Facts
Domain 2: Case Management (20%)
Case lifecycle design is central to how Pega applications model work, and this domain tests whether you can shape that lifecycle for realistic business requirements.
- Case type design: stages, steps, and how a lifecycle represents a business process
- Parent and child cases, and how work is decomposed and coordinated
- Routing and assignment, including how work reaches the right worker or work queue
- Service levels, urgency, and how deadlines escalate when work stalls
- Alternate stages and handling exceptions or deviations from the happy path
- Case data and how information is captured, passed, and reused across the lifecycle
When a question describes a business process, translate it into stages and steps first, then decide where routing, SLAs, or child cases belong. Candidates who skip that translation step often pick an answer that works technically but models the process poorly.
Data and Integration: Must-Know Facts
Domain 3: Data and Integration (20%)
This domain covers how an application gets, stores, and exchanges information, both inside the platform and with external systems.
- Data modeling: data types, properties, and how data objects are structured for reuse
- Data pages: sourcing, scope, and refresh behavior, including how they reduce redundant calls
- Integrating with external systems through connectors and services, and understanding the inbound versus outbound direction
- Handling integration failures gracefully and designing for error conditions
- Data transformation and mapping between your model and an external format
- Where to place integration logic so it stays maintainable and testable
Data pages are a frequent theme because they sit at the intersection of data modeling and integration design. Know the difference between how a page's scope and refresh strategy affect both correctness and performance. For a sense of how demanding this material is relative to other certifications, read our difficulty guide for the CSSA exam.
User Experience, System Administration, and Security
These three domains together make up 30% of the exam, with System Administration the largest at 15%.
Domain 4: User Experience (5%)
The smallest domain, but it rewards candidates who understand how the interface layer is assembled and reused.
- Building and reusing user interface components and templates
- Controlling when and how fields and sections appear and behave
- Keeping the interface consistent and responsive to the data it displays
Domain 5: System Administration (15%)
Operational knowledge matters at the senior level because architects are expected to understand how applications run, not just how they are built.
- Monitoring application behavior and diagnosing problems
- Managing how applications are packaged, moved, and deployed between environments
- Understanding background processing and how work runs outside a user session
- Troubleshooting performance and configuration issues
Domain 6: Security (10%)
Security questions focus on controlling who can see and do what within an application.
- Authentication and how users prove their identity to the application
- Authorization through access roles, privileges, and access control
- Restricting access to specific data or actions based on role or condition
- Applying the principle of least privilege when designing access
Do not treat Security as an afterthought. At 10%, it carries more weight than User Experience, and its questions tend to be concrete: given a requirement about who may do what, which configuration achieves it?
Question Formats and How to Read Them
Pega lists several possible question styles for its certification exams: single-response multiple choice, multiple-response multiple choice, matching or drag-and-drop, and reading-passage or scenario questions. The distribution across these types is not specified for this exam version, so prepare for all of them rather than betting on one.
- Single-response: One best answer. Eliminate options that violate a stated constraint.
- Multiple-response: Read the instruction carefully for how many selections are required, and evaluate each option independently as true or false.
- Matching/drag-and-drop: Usually tests whether you can pair a concept with its correct description or use. Match the certain pairs first.
- Scenario/reading passage: Extract the requirement, the constraint, and the goal before looking at the choices.
Because the exam is closed book, you cannot look up rule names or menu paths mid-test. Memory of how the platform actually behaves, built from hands-on work in the mission content and your own practice, matters more than memorized definitions. Our CSSA study guide lays out a full preparation path, and you can pressure-test your recall with the CSSA practice tests on the main site.
Registration, Fees, Retakes, and Test-Day Rules
Eligibility and Cost
You must already hold the Certified Pega System Architect credential, in any version, before you can sit for the Senior System Architect exam. Pega's preparation pathway for this credential is the Senior System Architect mission on Pega Academy. For eligibility specifics, see our guide to CSSA requirements and prerequisites. The fee is USD 190 per attempt plus applicable taxes, and it is subject to change, so verify the current price at registration. A full cost breakdown, including retake math, is in our CSSA certification cost guide.
Retake Policy
| Situation | Rule |
|---|---|
| After a first failure | Wait three calendar days |
| After a second failure | Wait 14 calendar days |
| Attempt limit | Three attempts per exam version in the 12 months beginning with your first attempt |
| Retake fee | Full fee each time |
That three-attempts-in-12-months cap is the most important retake fact. Because each attempt costs the full fee, rushing back in without closing your knowledge gaps is both expensive and risky.
Delivery and Identification
You can test at a Pearson VUE test center or remotely through OnVUE online proctoring. Acceptable identification is required in either case, and the specific requirements differ by delivery method, so read the Pearson VUE instructions for the option you choose well before test day. Scheduling windows and deadlines are covered in our CSSA exam dates guide.
Pass Rate: What Not to Assume
No official pass rate was found in the reviewed sources. The 70% figure is the passing score, meaning the share of the exam you must answer correctly, not the percentage of candidates who pass. Treat any specific pass-rate number you encounter with skepticism unless it cites a verifiable source. We discuss what is and is not known in our article on the CSSA pass rate.
Scheduling Your Review Around the Weights
You do not need a generic study template, but you should allocate review time in proportion to the published weights. Here is one way to sequence a focused review, front-loading the heaviest and most interconnected domains.
Application Development
- Rule resolution, inheritance, and layering decisions
- Reuse versus one-off configuration trade-offs
Case Management
- Stages, steps, routing, and service levels
- Parent and child case coordination
Data and Integration
- Data pages, scope, and refresh behavior
- Connector and service design, plus error handling
System Administration, Security, and User Experience
- Monitoring, deployment concepts, and access control
- Interface reuse, then a timed full-length practice pass
The reasoning: Application Development concepts such as rule resolution and inheritance underpin how you reason about the other domains, so they come first. Case Management and Data and Integration build on that foundation. The smaller domains come last, partly because they are lighter and partly because they make a good bridge into timed practice.
Common Mix-Ups to Avoid
- Mixing exam versions. The '25 exam has six domains; the '24.2 exam has an eight-domain outline. Use the '25 objectives only.
- Confusing the senior exam with its neighbors. The System Architect and Lead System Architect exams are separate credentials with different scope.
- Mistaking the passing score for a pass rate. 70% is a threshold, not a statistic about candidates.
- Treating mission quizzes as real questions. They are practice, not previews of the actual exam.
- Forgetting the NDA time. Accepting it counts against your allotted time under Pega's general guidance.
- Assuming the credential never changes. Certifications currently do not expire, but Pega reserves the right to impose recertification requirements.
Key Takeaway
Spend your effort in proportion to the weights: master Application Development first, then Case Management and Data and Integration, and keep Security, System Administration, and User Experience sharp enough to avoid easy losses. Verify the exam version, fee, and policies on Pega Academy before you book.
