About this course

This course gets you ready to pass the EST examination, including the practical assessment required by the EWRB.

Once you get your EST registration, you'll be able to service appliances, replace fixtures and fittings (not contained within a switchboard), including disconnection or connection to power supply rated at no more than 1000 volts. This course meets the requirements of the Electrical Workers Registration Board (EWRB) as a course of instruction suitable for examination entry and assessment of practical skills.

After you finish your block course, we'll sort your ASPEQ examination booking at a time that works for you.
