These degrees are designed to provide the student introductory information into the sciences that would be a foundation for continued study in a bachelor's degree program. Students can choose to follow certain specialties that they will expand on in the next level. The fields of study could include chemistry, physics, biology, computer science, earth science, engineering, and environmental science. Students choosing to go directly to the workforce with the two-year degree should receive an advantage over other applicants with only high school diplomas. In a current job, they can gain valuable skills toward recognition or promotion.
