Generally, cabinetmakers aren't required to have formal education past a high school diploma or its equivalent to work in the field. Without formal education in the field, most employers will look for relevant work experience before hiring you. With a diploma or certificate in furniture and cabinetmaking on your resume, however, you may find that you stand out from other job applicants. Additionally, employers may ask to see examples of your work, so keeping a portfolio of your designs can be helpful.
