Technical skills are specialized skills that are practical. They can be physical and mental labor or non-physical, such as working at a computer all day. Physical and mental labor may come in the form of an offshore diver who caps underwater oil well leaks. Contrast this to an auto worker on an assembly line who does simple, repetitive tasks. Technical skills are often not repetitive or simple.
Some examples of technical skills include mechanics, information technology, mathematics, and science. These skills can require years of specific training, and in many cases, advanced training to master. Another example of technical skills includes a stock analyst who is able to determine specific buy and sell points for a stock. Or they may determine the fair value of a company, which can show if a company is over or undervalued.
