You can build the profession you've always desired with the aid of PTTI! To apply for training, obtain a high school diploma, pass the aptitude tests, submit to a drug test, and show mechanical ability, among other requirements, are necessary. Before beginning employment on construction sites, electrical apprentices in California and Texas must register. Additionally, in some places, you need a license to work as an electrician. Like PTTI, Electrical Trade School demonstrates a route to more formal training in the trade. The majority of electricians complete 4- to 5-year apprenticeship programs to master their trade. Electrical systems theory and practice are combined in electrician programs. Most states require an electrician's license before you may begin working. PTTI is one of the states' referable institutes.
