There are two main skills required in medical transcription. The first is the ability to type with sufficient speed or be able to build up to a sufficient speed. Sixty words per minute would be the minimum speed. Faster speeds allow you to make more money in less time. The other skill needed is a knowledge of medical and pharmaceutical terms.
Many community colleges teach courses in medical transcription.
Once you do begin working in transcription it will be vital for you to stay abreast of new medical terms and especially new drugs that come on the market. There are several web sites that can help you with staying current on terms and products. The first place to look is right in your neighborhood. Most transcriptionists work out of their homes. You have the benefit of being your own boss.
