Today's trained technicians in alternative energy fields are finding even more career opportunities open to them as the United States and the world turn to green technology to power their homes and businesses. Wisconsin's Gateway Technical College is training workers for green collar careers in geoexchange heating and cooling systems, wind power industry, sustainable energy systems and fresh water resources. Integral to effective programming is assessing skill competencies, so Gateway is using National Occupational Competency Testing Institute (NOCTI) assessments to measure the skills of those entering and leaving its wind technician program. The field of alternative energy is growing quickly in its technical complexity, and Gateway wants to do its part to contribute.
