Employers have their own specifications for would-be apprentices and these may be more stringent than the FAS criteria. For instance, the ESB asks for a minimum of a C on ordinary-level papers in the Junior Cert or equivalent in Irish or English, science (it is possible to substitute another approved subject), maths and any two other subjects. There is a very high demand for places so those selected are likely to have done considerably better.

Those with the best results are called for aptitude tests and candidates are then called for interview on the basis of their results in these tests. The ESB offers two types of electrical apprenticeship: transmission/ distribution and instrumentation (generating stations).

The transmission system is basically the network of lines and substations used to supply electricity to customers. Work in the area includes supply and maintenance of electricity, tracing and repair of faults and breakdowns as well as installation. Much of the work is outdoors.

In contrast, work in generating stations is indoors. It includes the installation and maintenance of electrical and electronic plant and equipment in the generating stations.

The apprenticeship lasts four years, with an initial six-month probationary period. The rates of pay, as of November 1st, 1998, are £4,038 for first year rising to £10,768 in fourth year.
