ServiceNow is heavily investing in training and certifications, as more and more companies are realizing the importance every day. This has been going on for over a decade, and the trust has grown rapidly over the past few years. The Certified Application Developer (CAD) is one of the earliest and longest-standing certifications introduced by ServiceNow.
Some may still remember the early days when there were only three ServiceNow certifications: CSA for admins, CAD for developers, and CIS for implementers. Now, there are over a hundred ServiceNow credentials for different personas, domains, and expertise. The interesting part is how fast the space is moving, with some being deprecated and others evolving.
For many ServiceNow Developers and Administrators, CAD was the second certification achieved, after the Certified System Administrator (CSA), as it marks a big shift from generic platform navigation, administration, and capabilities to a more technical and development-based approach. In the ServiceNow development world, these two usually come together as the entry point into this demanding market and a gateway to new opportunities.
So, if you’re here, you probably have the CSA certification or some experience with the platform. If so, you’re off to a great start. If you’re new and only evaluating your options, you’re in the right place to learn what you need before taking this path.
Having spent over a decade in the ServiceNow ecosystem, exploring various roles and wearing multiple hats, I came to realize how my technical knowledge of the platform and earning the relevant certifications had a positive impact on my career.
In this guide, I’ll take you on a journey of understanding what the ServiceNow CAD certification exam covers and how to prepare for it efficiently. I’ll explain the different domains of the exam, what features, tools, and capabilities they cover, and what comes next once you earn this certification. I’ll also share some of my experiences along the way.
Who Is This Path For?
If you’ve earned your CSA certification and are wondering what’s next, then you’re definitely in the right place! But even if you haven’t, it’s still the right path if you consider yourself technical or are interested in learning to build, fix, and improve in the IT world. You could be a Software Developer, Mobile App Developer, Software Engineer, Technical Lead, System Architect, Data Engineer, or just curious, as I once was.
As the name implies, it was originally designed for developers, engineers, architects, and those who design, build, and enhance the services, applications, and features on the platform. To get your CAD certification, you need some level of technical knowledge and experience in application development and/or system administration.
ServiceNow recommends six months of practical experience developing applications on the platform. However, everything relevant could help build that knowledge and experience. That could include your knowledge of coding and building applications. Or, it could be your development or admin experience with different applications and platforms.
When I started my ServiceNow CAD journey, I completed a range of training courses, including the Application Development Fundamentals. I stayed up to date with new release features, which helped me keep on top of the latest changes and enhancements. Over time, the add-on micro-certifications and delivery accreditations kept me going, especially when paired with AI and Otto skills. I was also lucky to see how they all work in a corporate instance and evolve as we’ve matured. I used that opportunity to gain experience and apply many of the features and capabilities to different platform solutions.
ServiceNow also keeps its training courses up to date with new releases, which helps you stay on top of the latest changes and enhancements.
Now, whether you are a ServiceNow customer, partner, or employee, or just new to the ServiceNow job market and interested in becoming a Certified Application Developer, this is the path for you.
Why the CAD Certification Matters
The CAD is one of the most recognized ServiceNow certifications in the market, ranking among the top three globally in terms of certification holders. It is a prerequisite for a couple of expert programs and supports your journey toward some of the ServiceNow Suite certifications.
The certification shows your ability to build robust applications to solve complex business challenges and contribute effectively to the broader ServiceNow ecosystem.
CAD is highly sought after by ServiceNow partners and customers looking to transform their digital experience. For many ServiceNow professionals and implementers, CAD was a turning point that opened up major opportunities and led to successful ServiceNow implementations and transformations.
With years of experience as a ServiceNow implementation specialist and certified practitioner, I can see how the platform knowledge and development skills I gained through the ServiceNow fundamentals, implementation, and advanced courses, followed by their dedicated certifications, have helped me earn industry recognition and competitive differentiation, leading to greater productivity and results.
When paired with relevant experience, these certifications offer a great opportunity to validate your expertise across the platform. This has become even more important as ServiceNow advances in its AI journey.
What to Expect on the Exam
This is one of those exams that has not changed much over the years – at least not in the format and structure of the exam. One day we may see how the shift toward AI tools and solutions will affect expectations…
The topics here are evenly spread across the exam, from designing data models and building user interfaces to implementing security measures, automating workflows, and integrating external data sources.
According to the ServiceNow exam blueprint, you’ll be tested on six domains and 22 subdomains, with 60 multiple-choice and multiple-select questions in 90 minutes. The domains are the key topics and specific objectives included in the exam.
This chart shows you the breakdown of domains and their share of exam questions.
You can register and schedule your exam through ServiceNow University, which redirects you to the Pearson VUE platform to book and take the exam online (proctored) or at an approved test center. After you complete the exam, you will receive your results, including a breakdown of domains and how you performed in each.
Deep Dive Into the Domains
The ServiceNow CAD exam covers platform features and functionality, applications and capabilities, and their architecture and configuration. The domains guide what to focus on, and the breakdowns suggest the topics you will be tested on.
Major themes include application creation and structure, including how to build tables using the Guided Application Creator, when to extend existing tables versus create new ones, and how to manage application files within the repository. Another key area is data management, specifically importing data via spreadsheets and mapping it correctly using Transform Maps and System Import Sets.
The CAD exam also tests knowledge of user interface configuration, such as designing forms with sections and generating basic charts directly from list views. Scripting, automation, and security form the remaining focus areas. For example, you must understand client-side and server-side APIs, recognize valid methods for both GlideUser and GlideForm, as well as the purpose of Script Includes as centralized, reusable script functions.
The exam also tests security concepts, such as table-level read access and script protection policies. Automation is represented by scenarios requiring the correct configuration of scheduled jobs, event triggering, and the logic behind email notification weighting when multiple alerts apply to a single record.
In this section, I have explained what each domain covers, what is included, and what to expect.
This domain covers the fundamentals of application design and creation on the platform.
First, you need to understand how to find out if an application is a good fit with ServiceNow. You don’t want to reinvent the wheel if a similar application is available out of the box. Then focus on designing and implementing a data model that works best, considering the data schema and how data connects and relates to other data on the platform.
This domain covers a lot about creating applications and modules, and using application scope for your builds.
This domain focuses on delivering a modern experience, especially through the user interfaces such as Workspaces for the agents and Employee Slate for the employees.
You need to understand the anatomy of a list and a form, and how to configure them. This includes creating, designing, and customizing forms, as well as adding or removing fields from forms and tables.
Scripting in ServiceNow is a vast topic, but for this exam, you need to understand the basics of client-side versus server-side scripting to maintain and enhance an instance effectively. You will be expected to know when and how to write, test, and debug client-side scripts for the desktop, as well as handle server-side scripts. You also should know how to use a Record Producer as an application’s UI.
Resources:
I have to be honest with you, this is an area that requires more practice. You need to understand application and access control, specifically Access Control List (ACL) rules that restrict access to data by requiring users to pass a set of requirements before interacting with it.
The domain covers how to restrict access to applications and modules, and how to manually and automatically create, test, and debug Access Controls. You should also know how to use GlideSystem methods to script security and use application scope to protect application artifacts.
This domain requires some knowledge of how to automate business processes across the enterprise using platform capabilities. You should know about writing, testing, and debugging Workflow and Flow Designer.
It also involves creating and using application properties. In addition, you need to know how to create Events, Scheduled Script Executions, and Utils Script Includes. Additionally, you need to understand notifications, specifically how to trigger and process email.
This is probably a more technical topic for many ServiceNow learners. This domain covers how to move and manage data.
Specifically, you will be tested on how to import data in CSV or Excel format. You will also need to know how to integrate with an external data source using REST, including testing and debugging.
This domain focuses on the lifecycle of your development work. It covers how to locate and install applications.
You also need to understand how to use Delegated Development to manage source code and code review. In addition, you should know how to use the ServiceNow Git integration to manage source code.
How to Prepare for the Exam
The ServiceNow CAD exam is all about practice and experience. Keywords and definitions won’t help much if you don’t know how to find your way around development challenges. Similar to other ServiceNow exams, my strongest recommendation is to gain hands-on experience.
If you don’t have enough build experience, start by developing and practicing in a test environment. ServiceNow University offers labs with various on-demand courses, such as “Welcome to ServiceNow” and Application Development Fundamentals. They can provide guidance and help you practice and build.
You need to take your time and understand how to automate flows, manage access controls, work with database tables and columns, and learn about the difference between application development and deployment.
You don’t need to be a professional developer or scripting expert to go for the CAD exam – however, it is highly recommended that you know the fundamentals of JavaScript and how it’s used in ServiceNow. The Scripting in ServiceNow Fundamentals course covers both client-side and server-side scripting. In this course, you will learn to write and debug Client Scripts and Business Rules, configure UI Policies, and create Script Includes. Additionally, you will learn about essential APIs like GlideSystem and GlideRecord, and implement scripting within Flow Designer using subflows and custom actions.
If you’re new to JavaScript, you can start with the Introduction to Scripting in ServiceNow course, which provides a basic understanding of scripting. Next, try Learning JavaScript on the Now Platform, a video series with lab exercises that covers basic syntax, flow control, and some complex objects. There’s also the Scripting in ServiceNow Primer course for basic JavaScript principles and hands-on simulation tasks to work on simple Client Scripts, UI Policies, Business Rules, and Script Includes. I’ve also found this YouTube course helpful for beginners learning JavaScript.
ServiceNow University offers an advanced administration course if you’re interested in the admin side. There are also the Application Developer learning path, credential path, and career journey. There are also pathways for Application Developer Skills and Additional Recommended Courses for Application Developers.
The Developer Portal is another great source of information with learning plans for Administrators, Citizen Developers, and Application Developers. The good thing is the course materials are regularly updated based on the new releases, and you can switch to your desired release to get matching content (e.g. from Australia to Brazil).
For example, the ServiceNow Application Developer learning plan guides you through a comprehensive curriculum starting with creating custom widgets, client-side scripting, and using Flow Designer. As you progress, the training covers specialized areas like developing domain-separated applications and developing Virtual Agent topics, alongside core integration and testing concepts in outbound REST integrations, Scripted REST APIs, and using the Automated Test Framework (ATF).
To round out your platform expertise, the final modules focus on managing backend logic and access by covering Scheduled Script Executions and Events, securing applications against access from other applications, Service Portal introduction, and application properties.
These courses, along with some of the ServiceNow University courses, can help extend your knowledge and prepare you for the CAD exam and beyond. I still enjoy reviewing these courses after a decade of working with ServiceNow, especially when a new release goes live. There’s always something new to learn, especially with all the innovations and AI advances.
Another effective way to build with confidence is on a Personal Developer Instance (PDI), which you can request for free on the ServiceNow Developer site. It provides you with an out-of-the-box environment in your desired release, with admin access and the ability to install and work on most of the applications you need, including many paid ones.
You can use your PDI to play around, break things, and then fix them. You can try creating new features or rebuilding existing functionality. This is the best way to see how things look with the base configurations versus a customized corporate environment.
My advice would be to explore and experiment. Set some goals for yourself and work towards them. Try to learn a new thing every day and put it into practice. And finally, use every opportunity to design, configure, build, and deploy.
