what is the minimum eligibility for medical transcription?

I am a medical transcriptionist/editor and I have not gone to school for MT ever. However, this is a very rare case as I was unbelievably lucky. I applied at a hospital for a clerical job and when I went for my interview they gave me a transcription test when I thought I was coming in for a basic typing test. I had never heard of MT at that time. Medical transcription is this: Any time you go to the doctor or the hospital the doctor will check you out and ask you questions and then he will go pick up a phone and call a number that will connect him to a machine that records. He then will talk into the phone about you and why he saw you and how they treated you. Then the medical transcriptionist in an office, hospital or even some work at home (like me) will go on a computer and the computer connects to the same machine that recorded the doctor’s voice. The MT wears a headphone and there is a pedal under the desk. Push the pedal in the middle with your foot and it plays, to the right and it stops and to the left it rewinds. So we hear the doctor and start typing what he/she says so that when we are done we have a report that doctor can check it and sign it and then that will go in your chart so there is a record of your care so the doctor or anyother doctor can see it and help take care of you better in the future. Also, technology has really changed MT and now there is MT software that can listen to the doctors recordings and can type up the reports however there are still many mistakes and so MTs like myself now have to listen through and fix all the corrections the computer makes and we are called editors when we do that. I think in order to be an MT you have to have good grammar skills, be able to sit for long periods at a time and have good listening skills. After that most MTs go to vocational school and have to take medical terminology, anatomy and physiology and MTspecific courses. I don’t believe anyone can learn MT at home but there may be exceptions to the rule like myself about not going to school. You really will have a lot of questions. I was so lucky that I was hired because someone saw I had potential to learn and then I had a mentor who trained me one and one but that is a rare occasion.
* I used the example for a doctor as he in the above, of course woman are doctors as well.
