Southern Illinois University Carbondale's engineering programs sit inside the College of Engineering, Computing, Technology, and Mathematics, a college built around six schools: Civil, Environmental, & Infrastructure Engineering; Computing; Applied Engineering & Technology; Electrical, Computer & Biomedical Engineering; Mathematical & Statistical Sciences; and Mechanical, Aerospace & Materials Engineering. For international applicants comparing options, SIU's pitch is straightforward: ABET-accredited degrees, a genuinely high admit rate, and total costs well below most US flagship engineering schools, at a Research 1 university with graduate programs that U.S. News & World Report ranks third among Illinois public universities in Computer, Civil, Electrical, and Mechanical Engineering.
This guide covers acceptance rate, fees, admission requirements, how to get in, English proficiency rules, and career outcomes specifically for SIU's engineering programs.
Acceptance Rate
SIU does not publish a college-specific (engineering-only) acceptance rate. What is verifiable:
- SIU's overall undergraduate acceptance rate is commonly reported by third-party aggregators (Niche, AcceptanceRate.com) in the high-80s to mid-90s percent range; this is a third-party estimate, not a figure SIU itself publishes as a single official statistic.
- Undergraduate engineering admission at SIU is test-optional: the College of Engineering, Computing, Technology, and Mathematics evaluates applicants primarily on high school course patterns (especially math sequence completed), GPA, and completed documentation rather than a comparative, holistic review, which is consistent with the university-wide admissions model.
- Graduate admission is decentralized by department. Engineering graduate programs (Civil, Electrical, Computer, Mechanical, Biomedical) each set their own bar; SIU does not publish a single engineering-wide graduate acceptance rate.
Because undergraduate engineering admission leans on GPA and a minimum math/science course pattern rather than a competitive applicant pool, well-prepared applicants with a clean academic record are admitted at a high rate, consistent with SIU's broader access-oriented admissions model.
Fees and Cost of Attendance
SIU's engineering programs are billed at the university's standard international student rate; the College of Engineering, Computing, Technology, and Mathematics does not carry a separate, higher tuition band the way SIU's College of Business and Analytics does. Based on SIU's own International Admissions cost figures:
| Cost item | Undergraduate (International) | Graduate (International) |
|---|---|---|
| Tuition & fees | ~$24,439/year | ~$25,566/year |
| Living expenses (food, books, transportation, personal) | ~$16,165/year | ~$12,174/year |
| Total estimated cost of attendance | ~$40,604/year | ~$37,740/year |
These are the minimum amounts SIU requires international applicants to document for visa/I-20 purposes; SIU notes they are estimates subject to change. High-achieving international students may qualify for reduced tuition rates comparable to in-state resident rates on a case-by-case basis. Graduate engineering students are also frequently able to access graduate/research/teaching assistantships that combine a stipend with a tuition waiver, though availability varies by department (Electrical, Computer & Biomedical Engineering and Mechanical, Aerospace & Materials Engineering both run active, externally funded research labs, which is where most assistantship funding originates); confirm current openings directly with the specific school you're applying to.
Admission Requirements
Undergraduate
- Completed online application and $40 nonrefundable application fee
- Official secondary school transcripts, translated into English if not originally issued in English
- Minimum 2.75 GPA (4.0 scale) for freshman applicants; minimum 2.0 GPA for transfer applicants
- A high school math sequence through at least pre-calculus is strongly recommended for engineering majors, since it directly affects which introductory math and physics courses a student can start in
- Evidence of English proficiency, or eligibility for the CESL conditional admission pathway (see below)
- Financial documentation sufficient to meet SIU's published minimum cost-of-attendance figures, required for I-20/visa processing
- SAT/ACT scores are not required (test-optional)
Graduate
Requirements vary by school/department within the college, but generally include:
- Online application through SIU's Graduate School, with a $65 (domestic) or $75 (international) application fee
- Official transcripts from all post-secondary institutions attended
- Statement of purpose
- Letters of recommendation (typically 2-3)
- Resume/CV
- English proficiency scores (unless exempt)
- GRE scores for some engineering programs; policy varies by school, so confirm directly with the specific department (Civil, Electrical, Computer, Mechanical, or Biomedical Engineering) before applying
Because SIU's engineering graduate admission is run department by department rather than college-wide, always confirm the exact document list and standardized test policy with the specific program.
How to Get Into SIU's Engineering Programs
-
Complete a strong math and science course sequence in high school. Because SIU's undergraduate engineering review weighs course pattern and GPA heavily rather than essays or extracurriculars, having completed pre-calculus (ideally calculus) and lab sciences gives you the strongest foundation for both admission and your first-semester course placement.
-
Submit a complete, accurately translated transcript early. SIU's process is document-driven; incomplete or untranslated transcripts are the most common cause of delayed admission decisions.
-
Use the CESL conditional admission pathway if your English score isn't there yet. If you meet SIU's academic requirements but haven't reached the required IELTS/TOEFL/Duolingo/PTE score, SIU can admit you conditionally into its Center for English as a Second Language. You complete English coursework, receive a Certificate of Completion, and move directly into your engineering program without a new application.
-
For graduate applicants, contact the specific school directly. Because Civil, Electrical, Computer, Mechanical, and Biomedical Engineering each run separate graduate admissions, reaching out about GRE policy, funding availability (especially research/teaching assistantships), and faculty research fit before applying meaningfully strengthens an application.
-
Have financial documentation ready at application time. International admission is tightly linked to visa processing, so proof of funds meeting SIU's published cost-of-attendance minimum should be ready before you apply, not after admission.
English Proficiency Requirement (IELTS/TOEFL)
SIU's engineering programs follow the university-wide English proficiency thresholds; there is no separate, higher bar specific to engineering.
| Test | Undergraduate minimum | Graduate minimum |
|---|---|---|
| IELTS Academic | 6.0 | 6.5 |
| TOEFL iBT | 68 (520 PBT) | 80 (4.5 on the redesigned scale for tests taken on/after January 21, 2026) |
| PTE Academic | 47 | 64 |
| Duolingo English Test | 95 | 115 |
Applicants who fall short of these minimums but meet SIU's academic requirements can be admitted conditionally into the Center for English as a Second Language (CESL), complete coursework, and move into their degree program without a new application. For the full breakdown of SIU's testing policy and the CESL pathway, see Southern Illinois University Carbondale: Acceptance Rate, Fees, IELTS/TOEFL Requirements, and How to Get In.
Career Outcomes
SIU does not publish a single, prominently displayed engineering-specific employment rate or average starting salary figure; that data is tracked through SIU's Career Development Center in partnership with NACE's First Destination surveys and is best confirmed directly with the Career Development Center or your target department for current class-year figures. What is verifiable:
- SIU's Civil, Computer, Electrical, and Mechanical Engineering programs are ABET-accredited through the Engineering Accreditation Commission, and the Biomedical Engineering BS recently earned ABET accreditation as well, which matters for licensure pathways (FE/PE exams) and for employer recognition of the degree.
- Graduates of these STEM-designated degree programs qualify for the 24-month STEM OPT extension on top of the standard 12-month Optional Practical Training period, giving up to three years of US work authorization after graduation without immediately needing an H-1B.
- SIU's engineering students have access to design and research experiences including the Formula SAE competition and college research facilities, which give hands-on project experience relevant to engineering employers.
- SIU runs a Global Career Accelerator, an online, credit-bearing program connecting international students to real-world projects with companies including Intel, aimed at giving international students US-facing work experience before graduation.
If a specific engineering discipline's placement rate, starting salary, or employer list is central to your decision, confirm current figures directly with SIU's Career Development Center or the relevant school within the college, since this data was not available in a single published, citable source at the time of writing.
