Servicenow Application Development Fundamentals

This hands-on course will provide training and lab work to support application creation in ServiceNow.

Attendees will build an award-winning loaner equipment application by working through a checklist of considerations for application creation, including decisions such as creating an application table vs. extending an existing table, and determining how users will interact with the application.

Detailed labs that reinforce good practices in these areas support the topics covered in class.

Following this course, ServiceNow recommends that attendees have at least two to three months of hands-on experiences with ServiceNow before attempting the Certification Exam.

Further details regarding this exam, including an exam blueprint, can be found on the Certified Application Developer page. Successful candidates will be awarded a “ServiceNow Certified Application Developer” certificate.
