What is an Apprenticeship?
Apprenticeship is an industry-driven, high-quality career pathway where employers can develop and prepare their future workforce, and individuals can obtain paid work experience, classroom instruction, and a portable, nationally-recognized credential.
Why Become an Apprentice?
Through an apprenticeship program, you can obtain paid, relevant workplace experience while acquiring the skills and credentials that employer’s value. 94% of apprentices who complete an apprenticeship retain employment, with a national average annual salary of $70,000.
