When I applied to work as a receptionist/transcriptionist there were only seven requirements as I remember they were...
Knowledge of medical terminology. Above-average spelling, grammar, communication and memory skills. Ability to sort, check, count, and verify numbers with accuracy. Skill in the use and operation of basic office equipment/computer; eye/hand/foot coordination. Ability to follow verbal and written instructions. Records maintenance skills or ability. Above-average to excellent typing skills.
I also had to have extensive knowledge of medical practices, and have two years experience.
