How to pass the ServiceNow CSA exam in 2026
The Certified System Administrator exam is the entry point for every ServiceNow career path. This guide covers the Zurich domain weights, a week-by-week study plan, and the mistakes that cost people a $225 retake.
What is CSA?
CSA stands for Certified System Administrator. It is ServiceNow's foundational certification, the one that validates you can configure, manage, and troubleshoot a ServiceNow instance from an admin perspective.
Every other ServiceNow certification assumes you have CSA-level knowledge. Want CIS-ITSM? You need CSA first. Want CAS-PA? CSA first. Want CAD? CSA first. It is the prerequisite for the entire certification tree.
The exam covers six domains, ranging from basic platform navigation to database administration and scripting fundamentals. It is broad by design. ServiceNow wants to confirm you understand how the platform works as a whole before you specialize.
For hiring managers, CSA is the minimum filter. ServiceNow admin job postings almost universally list it as a requirement. Having it does not guarantee a job, but not having it will often disqualify you from the interview.
Exam format and logistics
The CSA exam has approximately 60 questions. You get 90 minutes. The passing score is around 70%, though ServiceNow uses scaled scoring and does not publish the exact cutoff.
Most questions are multiple-choice with a single correct answer. Some ask you to select two or three options. Those multi-select questions are the hardest to get right because partial credit does not exist. Miss one correct option out of three and you score zero on that question.
The exam runs on the Pearson VUE platform. ServiceNow migrated from Kryterion/Webassessor in November 2025. You can take it at a Pearson VUE testing center or online with the OnVUE app. The online option requires a webcam, a clear desk, and no second monitor.
All questions target the Zurich release. If you study from Xanadu or Washington documentation, some answers will be wrong. Always check the release selector on docs.servicenow.com before trusting a page.
The exam costs $450 for the first attempt. Retakes cost $225. Unlike CIS-DF, there is no free first attempt for CSA. That makes preparation worth more per dollar: a $9.99 practice test versus a $225 retake is a 22x return on investment if it helps you pass on the first try.
Domain breakdown and weights
ServiceNow splits CSA into six domains. The weights determine how many questions come from each section. Study time should match these proportions. If you spend equal time on all six, you are over-preparing for the small domains and under-preparing for the ones that carry the exam.
| Domain | What it covers | Weight |
|---|---|---|
| Database Administration and Security | Tables, columns, ACLs, data policies, import sets, LDAP, SSO, encryption, roles, groups, user administration | ~27% |
| Self-Service and Process Automation | Service Catalog, service portal, knowledge management, workflow/flow designer, notifications, SLAs, inbound email actions | ~20% |
| Configuring Applications for Collaboration | Task management, incident/problem/change, visual task boards, assignment rules, Connect Chat, teams | ~20% |
| Introduction to Development | Scripting basics (client scripts, business rules, UI policies, UI actions), script includes, GlideRecord, GlideSystem, debugging | ~15% |
| Instance Configuration | Plugins, update sets, system properties, application menus, lists, forms, related lists, views, homepages, dashboards | ~11% |
| Platform Overview and Navigation | UI components, application navigator, lists, forms, platform architecture overview, personas | ~7% |
Database Administration and Security alone is 27% of the exam. That is more than a quarter of your score from one domain. If you are weak on ACLs, data policies, or user/group/role relationships, fix that before anything else.
The two 20% domains (Self-Service and Collaboration) together account for 40%. Combined with Database Admin, those three domains make up 67% of the exam. Two-thirds of your score comes from three sections. Prioritize them.
Platform Overview at 7% is the smallest domain. Do not spend a full week on it. A single pass through the docs is enough. The questions are straightforward if you have spent any time on the platform.
The CSA practice test on Udemy has 392 questions mapped to all six domains. Every question includes a per-option explanation that links to official Zurich documentation. The course costs $9.99 with the referral link below.
A retake costs $225. Preparation costs less than a coffee.

This plan assumes 8 to 10 hours per week. CSA is broader than CIS-DF, so it needs an extra week. If you have more time, compress it. If you have less, stretch to 7 weeks but do not skip the timed practice exams in week 5.
Set up a Personal Developer Instance (PDI) from developer.servicenow.com. Spend this week getting comfortable: navigate the application menu, explore lists and forms, create a few test records, experiment with filters and views. Cover the Platform Overview (~7%) and Instance Configuration (~11%) domains. These are the smallest slices of the exam, but they build the vocabulary everything else depends on.
This is 27% of the exam. Learn how tables and columns work, how to create and modify them, and how data dictionary entries control field behavior. Study ACLs in depth: how they evaluate, how they interact with roles, and what happens when multiple ACLs apply to the same record. Practice creating roles, groups, and users in your PDI. Cover import sets, LDAP configuration concepts, and data policies. Do not move on until you can explain the ACL evaluation order without checking notes.
Another 20% domain. Build a service catalog item from scratch in your PDI: create the item, add variables, attach a workflow or flow, configure approvals, and test the request. Study knowledge management (knowledge bases, article lifecycle, feedback). Learn how SLAs work: when they attach, how they pause, and what triggers a breach. Cover notifications and inbound email actions. Hands-on practice matters here because the exam tests "what happens when" scenarios.
Cover the Collaboration domain (20%): task management, incident/problem/change workflows, assignment rules, visual task boards. Then move to Introduction to Development (15%): client scripts, UI policies, business rules, UI actions, and when to use each. You do not need to write complex GlideRecord queries from memory, but you need to understand server-side versus client-side execution, when a business rule runs versus a UI policy, and how to debug using the system log.
Take at least two full-length timed tests. 60 questions, 90 minutes, no pausing, no looking things up. After each test, review every wrong answer and identify which domain it came from. If any domain scores below 75%, go back to that section's documentation before exam day. Aim for 80%+ on practice tests. Stress during the real exam eats 5 to 10 points from your score, so you need that margin.
How to use your PDI effectively
A Personal Developer Instance is free from developer.servicenow.com. You can spin one up in about two minutes. It comes pre-loaded with demo data, which means you get incidents, problems, changes, users, and catalog items to work with immediately.
The mistake most people make: they read documentation for hours and never open the PDI. CSA is a hands-on exam. Questions describe scenarios ("a user reports they cannot see a field on the incident form, what is the most likely cause?") and expect you to know what you would check first. That intuition comes from clicking around the platform, not from reading about it.
Build something real. Create a service catalog item that provisions a laptop request with an approval workflow. Set up ACLs that restrict a custom table to a specific role. Configure an SLA that breaches after 4 hours if a priority-1 incident is not resolved. Each of those exercises covers two or three exam domains at once.
Your PDI resets after a period of inactivity (usually 10 days). That is fine. Rebuilding from scratch is good practice. The second time you set up a catalog item or ACL configuration, it takes a quarter of the time and sticks in memory better.
5 mistakes that fail people
Underestimating ACLs. Access control lists are the backbone of the Security domain, and that domain is 27% of the exam. People study ACLs once, think they understand them, and then get tripped up by evaluation order questions. Know the difference between table-level, field-level, and row-level ACLs. Know what "requires role" versus a script-based ACL condition means. Know what happens when no ACL matches.
Skipping the Service Catalog build. Reading about catalog items is different from building one. The exam asks about variable types, variable sets, order guides, record producers, and the request fulfillment process. If you have never created a catalog item with variables and a flow, these questions will feel abstract. Spend 90 minutes in your PDI building one end to end.
Confusing client-side and server-side. Client scripts run in the browser. Business rules run on the server. UI policies are client-side but have a server-side option. The exam tests when each fires, what each can access, and what happens if you use a GlideRecord call in a client script (answer: performance problems, because it makes a synchronous server call). Draw a chart of what runs where and memorize it.
Studying from the wrong release. ServiceNow documentation defaults to the latest release, but the CSA exam targets Zurich. Features introduced after Zurich will not appear on the test, and features that changed between releases will have different correct answers. Always set the release selector to Zurich before reading a documentation page.
Never simulating exam conditions. Taking a practice test while pausing to look up answers teaches you content but not exam performance. The real test gives you 90 minutes, no references, and a proctor watching. Practice under those conditions at least twice. Close all tabs, set a timer, and commit to the full 60 questions without stopping.
CSA or CIS-DF first?
This is the most common question from people starting their ServiceNow certification journey. The short answer: if you are new to the platform, take CSA first. If you already work on ServiceNow, consider taking CIS-DF first while the free first attempt is available through June 2026.
CSA and CIS-DF test completely different material. There is almost no overlap. Passing one does not help you pass the other. But CSA gives you the platform vocabulary that makes every other certification easier to study for, including CIS-DF.
