Frequently asked questions

What is the ServiceNow CAD certification?

The Certified Application Developer (CAD) certification validates your ability to build and deploy custom applications on the ServiceNow platform. It is typically pursued after gaining experience with the CSA fundamentals.

Do I need the CSA before taking the CAD exam?

ServiceNow recommends having CSA-level knowledge before attempting the CAD. While it is not a hard prerequisite, understanding the platform fundamentals makes the development topics significantly easier to grasp.

How many questions are on the ServiceNow CAD exam?

The CAD exam consists of 60 questions to be completed in 90 minutes, the same format as the CSA. The content is more technical, focusing on application development and scripting.

How hard is the ServiceNow CAD exam compared to the CSA?

The CAD is generally considered more difficult than the CSA. It requires hands-on development experience and a solid understanding of both client-side and server-side scripting in ServiceNow.

How long should I study for the ServiceNow CAD?

Most candidates with development experience spend 6–10 weeks studying for the CAD. Hands-on practice in a Personal Developer Instance (PDI) alongside question-based study is the most effective approach.

Does my employer cover the CAD exam cost?

Many organizations with ServiceNow development teams reimburse certification costs. The CAD is especially valuable for employers building custom applications on the platform — it is worth asking your manager or HR department.
