O*Net is an online career exploration tool funded by the US Department of Labor. It has so many great features, including a keyword search where you can enter key terms or job titles you are interested in and the tool will break down the types of technical skills, abilities, knowledge and even job related tasks associated with it. It is a great exploration tool to help you learn the jargon in your field of interest and identify which skills you may already have and those you need to enhance.
Another great feature about O*Net is that you can take their Interest Profiler Assessment to learn about how your interests correlate with various careers. Once you have completed the Interest Profiler, and you have been given your 3-letter interest code, you can enter them here here to see which careers correspond with that code.
Pretty cool tool!
