ServiceNow Scripting Training
Master the JavaScript layer of ServiceNow. GlideRecord, business rules, Script Includes, client scripts and GlideAjax, plus the debugging habits that keep automation reliable in production.
ServiceNow scripting training focuses on the JavaScript layer of the Now Platform. You learn GlideRecord, business rules, Script Includes, client scripts, UI actions and GlideAjax, and you learn the debugging techniques that keep automation reliable when it runs in production.
Who this course is for
Prerequisite: Basic ServiceNow administration. If you are new to the platform, 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No outdated screenshots.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
7 modules and 3 projects, updated to the current release. Every module maps to real Scripting 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.
Assignment automation
Write a before business rule and a Script Include that assign records by category and priority, with tests for the edge cases.
Client form logic
Build a client script and GlideAjax call that fetches server data and updates the form without a reload.
Slow script rescue
Take a deliberately slow, buggy business rule and rewrite it to be correct and fast, using the debugger and logs.
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 aligned exam and finishes with an IT Canvass certificate plus a certification roadmap. Scripting is a large part of the CAD exam (US$300, ServiceNow University). 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.

How IT Canvass compares
Against a typical training provider, this Scripting 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 aligned 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 Scripting. 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 Scripting
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
I stopped copying scripts I did not understand. Now I can explain why a business rule fires and fix it when it does not.
The debugging module alone was worth it. I fix my own scripts now instead of raising a ticket.
Every session was hands on. The slow script rescue exercise is exactly the kind of thing I get asked in interviews.

The questions people actually ask before enrolling, answered plainly.
