Learning ten key is a little bit different than learning to type. For example, the home row contains the numbers 4,5,and 6, and is typed by the index finger, middle finger and ring finger respectively. The right hand is used, though there are left handed people who modify ten key for the left hand. There are also some keyboards with the ten key pad on the left side of the keyboard.
Instead of measuring speed of ten key proficiency with words per minute (wpm) measurements as in typing, ten key is measured in either keys per minute (kpm) or strokes per minute. Most use the kpm designation when seeking employees and set a minimum kpm for applicants. Minimal proficiency in ten key is considered at least 140 kpm, though some companies which require only a little data entry might accept less.
Employment agencies frequently ask for applicants to take typing and ten key tests so they can pass this information along to interested employers. Usually most people gain proficiency in a short period of time, since there are fewer keys to learn. If you claim a certain kpm rate, however, you must be certain you can prove consistent error free ten key typing at this rate.
Few traditional ten key classes exist for those who wish to become proficient. However, there are some excellent software based courses that can easily help one acquire the skills to perform proficient ten key work. Many consider one the best of these to be Mavis Beacon Teaches Typing, which teaches not only traditional keyboard typing but also ten key fingering. The software is available on both PC and MAC platforms and tends to be fairly inexpensive, usually about 20 US dollars (USD).
With a few weeks of practice, you can usually learn all the keys of ten key and demonstrate proficiency. If you are already an accomplished typist, the skills may take less time to acquire.
