ServiceNow Developer Training
Become a ServiceNow developer. Build scoped applications, write Glide server and client scripts, design flows and REST integrations on a real instance, mapped module by module to the CAD exam.
ServiceNow Developer training teaches you to build and extend applications on the Now Platform. You work with scoped applications, server and client scripting using GlideRecord and GlideAjax, UI Builder, Flow Designer and REST integrations, and you finish aligned to the Certified Application Developer (CAD) exam.
Who this course is for
Prerequisite: Basic ServiceNow administration (CSA level). If you are new, take the Admin and Development track first.
What makes this different
You build, not just watch
From the first session you are on your own developer instance, configuring, scripting and breaking things safely. That is what makes it stick.
Taught on the current release
No outdated screenshots. Everything maps to the release ServiceNow runs today, including current AI and platform features.
One trainer who still implements
One working consultant for the whole batch, no rotation, so the teaching is consistent and grounded in real projects.
Support continues to the offer
Resume review, mock interviews on real scenario questions, and referrals. Support does not stop when the last class ends.
Curriculum
8 modules and 3 projects, updated to the current release. Every module maps to real Developer work and expands into its full topic list, practised on a live developer instance.

What you'll be able to do
Real projects you'll build
Interview-ready scenarios on a live instance, not toy demos.
Scoped approval application
Build a custom scoped app with its own tables, roles and ACLs, a request form, an approval flow and notifications, then package it in an update set.
Outbound REST integration
Call an external API from a business rule and a flow action, handle authentication and pagination, and log failures cleanly.
ATF regression suite
Write automated tests for a catalog item and a business rule so a future change cannot silently break them.
Certification and hands-on
Every session runs on a real ServiceNow developer instance, so you configure and build rather than watch. The course maps to the CAD exam and finishes with an IT Canvass certificate plus a certification roadmap. The ServiceNow CAD exam costs US$300 (ServiceNow University, 2026). IT Canvass does not issue the official ServiceNow credential.
ServiceNow has an official certification catalog with four tiers: Expert (Certified Technical Architect, Certified Master Architect), Mainline (Certified System Administrator, Certified Application Developer, Certified Application Specialist and the Certified Implementation Specialist product tracks), Micro-Certifications (focused product skills such as Now Assist, Flow Designer and CMDB), and Suite Certifications (bundled credentials such as the ITSM and CSM Professional suites).
Certification facts. Vendor figures change, so confirm against the official ServiceNow catalogue before booking.

| Credential | ServiceNow CAD |

How IT Canvass compares
Against a typical training provider, this Developer course is taught on the current ServiceNow release, gives you your own developer instance from day one, and keeps one working consultant for the whole batch instead of rotating trainers. Every module is mapped to the CAD exam, sessions are recorded with lifetime access, and job support (resume review, mock interviews and referrals) is included in one transparent fee. Most providers still teach older release material, run slide-first sessions with limited lab time, and bill support and recordings as add-ons.
Fees and training modes
Choose how you want to learn Developer. No-cost EMI available on all modes.
Interactive live batches, weekday or weekend, with the full cohort and lifetime recordings.
Private one-on-one coaching at your pace, whether you need interview-ready fast or hands-on help with your current project.
Learn on your own time with recorded sessions, labs and Q&A doubt support.
Train your team on ServiceNow Developer Training
Tailored curriculum, flexible scheduling, a dedicated ServiceNow architect, and progress reporting for your managers. Delivered live online or on-site for cohorts of any size.
Your trainer
Neelima, ServiceNow Architect, 12+ years
I still deliver ITSM, ITOM and HRSD implementations for enterprise clients, so I teach from what is breaking in production this quarter, not from a slide deck. In class I show the patterns that scale and the mistakes that cost teams days.
Learner reviews
The scoped app project is what got me hired. I could show a real application and explain every design choice.
Scripting finally clicked because we wrote code every session and debugged it together, not just watched slides.
Cleared CAD five weeks after the course. The module to exam mapping told me exactly when I was ready.
