A career diploma is formal documentation a person receives after completing specialized college-level training for entry or advancement into a given profession. Typically, a diploma program is shorter than a full degree program. It takes between a few weeks and two years to complete, depending on the field.
In some cases, people earn a career diploma as a requirement for licensing or entry into a profession. A career diploma is a common route for someone to become a nurse's aide or a dental assistant. Even when not required for a job, earning a career diploma can improve qualifications for a job.
