The main education requirements for becoming a metal caster involve having a High School diploma and then attending a vocational school to complete a training program to gain the necessary skills to work with all types of metals. While not all companies require training programs, most do. Some companies allow employees to learn the trade through on-the-job experience. In this type of training, the employee starts off by working under an experienced caster. They may help to operate the machinery or bring the metal to the caster. As they gain experience in watching a caster, they are given the opportunity to begin working with the different aspects of casting. Once they have trained for at least one year, they are able to begin casting on their own.

Many companies now require casting certification through an exam. This exam is required after the completion of a training program. Not all states and countries have the same requirements, so it is important to check with the local standards in one's own area.

A caster must have knowledge of the different types of metals and their melting temperatures. This is one of the most important parts of the job, as melting metals is so dangerous. Without the proper understanding of metal temperatures, the caster can ruin the metal pieces and even put themselves in danger.

A caster must also have some math skills for the weighing of different metals. Along with math skills, good hand and eye coordination is crucial. The caster must be aware at all times while they are working with molten metals.
