The healthcare industry is booming--which means that now is a great time to become a healthcare aide. These caring professionals are responsible for completing the daily tasks that keep patients healthy and comfortable, such as serving meals, bathing, and monitoring medications. The Bureau of Labor Statistics projects that employment of home health aides will grow by nearly 50 percent through 2016. Training programs at vocational and technical colleges, nursing facilities, or online can prepare you for a career in this field.
