The skill standards cited here are abstracted from a report1 prepared jointly by the Electronic Industries Association (EIA) and the Electronic Industries Foundation (EIF). The project was funded in 1992 by the U.S. Department of Education's Business and Education Standards Program which is, in turn, an offshoot of the Secretary's Commission on Achieving Necessary Skills (SCANS) program. SCANS is most widely recognized for its America 2000 report.
