About this course

The EST course prepares you for registration as an Electrical Service Technician with the Electrical Workers Registration Board (EWRB). Once registered, you'll be permitted to service, repair and connect portable and fixed-wired single and three-phase appliances as defined by the EWRB EST scope of work.

The course combines self-directed online theory through The Learning Hive with practical training at your local Skills Trades Training campus.

Already registered as an Electrical Appliance Serviceperson (EAS)? The EST Upgrade course gets you to EST registration in just three days. 

Course format

The EWRB-approved EST course is available in two delivery modes. 

Block course - Eight days on campus across two weeks. The most common option for full-time learners and apprentices. 

Night classes - The same content delivered across 16 weekly evening sessions. Suits learners working full-time who can't commit to consecutive days off the tools. 

As well as attending these sessions, you'll also work through 21 online theory modules through The Learning Hive. Drop-in sessions are available nationally to connect with a tutor and get support with course content. 

Who this course is for

The EST course is for electrical workers working toward EWRB EST registration. It suits:

  • Anyone with a Trainee Limited Certificate (TLC) working toward EST sign-off with the EWRB
  • Workers who want the broader EST scope of work from the outset
  • Career changers entering the electrical trade who need a recognised qualification 

Entry requirements

To enrol in this course, you must:

  • Meet EWRB eligibility requirements for EST registration
  • Be able to safely participate in practical workshop activities
  • Provide evidence of a current first aid certificate (within the last 12 months)

This course is not suitable for people wanting to learn electrical basics with no intention of pursuing EWRB registration. If you already hold EAS registration, the EST Upgrade course is a faster and more cost-effective option.
