Associate of Science (A.S.) — Build Your STEM Foundation for Less
What Is the Associate of Science?
The Associate of Science is a two-year degree with a focus on science, technology, engineering, and mathematics (STEM). Like the A.A., it is designed as a transfer degree, but with heavier emphasis on math and science courses that prepare you for STEM bachelor's programs. The A.S. requires more rigorous coursework including Calculus, Chemistry, Physics, or Biology depending on your intended major. It is the ideal starting point for students who want careers in engineering, computer science, healthcare, or the natural sciences but want to complete their first two years affordably at a community college.
Who Is the A.S. For?
Students planning to major in a STEM field at a four-year university, future engineers, computer scientists, and healthcare professionals, budget-conscious students who want a strong math and science foundation, and career changers moving into technical fields.
Common Classes in a A.S. Program
Here are the 10 core courses you can expect to take in a typical Associate of Science program:
Calculus I & II
Covers limits, derivatives, integrals, and series. Required for virtually all STEM bachelor's programs.
General Chemistry I & II with Lab
Atomic structure, chemical bonding, stoichiometry, thermodynamics, and laboratory techniques.
General Physics I & II with Lab
Mechanics, thermodynamics, electricity, magnetism, and optics with hands-on laboratory experiments.
General Biology I & II with Lab
Cell biology, genetics, evolution, ecology, and organismal biology with dissection and microscopy labs.
English Composition I & II
College-level writing with emphasis on technical and scientific writing, research papers, and documentation.
Introduction to Computer Science
Programming fundamentals, algorithms, data structures, and computational thinking using Python or Java.
Statistics
Probability, data analysis, hypothesis testing, and statistical reasoning used in scientific research.
Linear Algebra or Discrete Math
Mathematical structures and reasoning used in computer science, engineering, and advanced mathematics.
Lab Science Elective
An additional lab science in your area of interest: Organic Chemistry, Anatomy & Physiology, Environmental Science, or Geology.
Public Speaking or Technical Communication
Oral and written communication skills with emphasis on presenting scientific or technical information clearly.
Career Paths With a A.S.
Salary ranges are approximate national averages and will vary by location, experience, and employer.
Pros
- Save 50-70% on your first two years of a STEM degree
- Smaller lab sections mean more hands-on time with equipment
- Strong transfer pathways to engineering and science programs
- Many community colleges have modern STEM labs and equipment
- Pell Grants can cover most or all of community college tuition
Cons
- STEM courses are demanding — requires strong time management
- Lab schedules can conflict with work hours
- Some competitive university programs prefer students who started at their institution
- Need to carefully match course sequences with transfer requirements
Expert Tips for A.S. Students
- 1
Take Calculus and Chemistry in your first year — these are prerequisites for nearly everything else.
- 2
Join the STEM club or tutoring center at your community college for study groups and networking.
- 3
Many universities offer guaranteed admission for A.S. graduates with a minimum GPA (often 3.0).
- 4
Do not skip the lab portions — STEM employers and grad schools look for hands-on experience.
