This paper describes the O*NET Center’s initial identification of “Hot Technologies.” A “Hot Technology” is a technology requirement frequently included in employer job postings. The concept of hot technologies was developed in order to enable a wide variety of customers to learn what types of software skills are in demand within the current United States economy. The hot technologies are incorporated within the primary O*NET websites. Hot technologies are distinguished by a fire icon. In the near future, the hot technology information will be available within the O*NET Web Services.
