Career Clusters: Forecasting Demand for High School Through College Jobs 2008-2018 presents forecasts on job opportunities and skill requirements through 2018, broken down by the 16 career and technical education (CTE) clusters. The report breaks down the best jobs within these clusters for individuals at the various education levels (high school graduate, some college/associate's degree, bachelor's degree and above), and finds that while it is still possible for individuals to achieve middle class status without a college degree, it has become increasingly difficult to find and secure such jobs.
