The University of Illinois Urbana-Champaign publishes a general university-wide TOEFL range for admission, but individual colleges — especially Grainger Engineering, Gies Business, and the Siebel School of Computing and Data Science (UIUC's computer science school, formerly the Department of Computer Science) — expect scores well above the published floor from competitive international applicants. TOEFL iBT is accepted alongside IELTS Academic across UIUC.
Does UIUC Accept TOEFL?
Yes. UIUC accepts TOEFL iBT as proof of English proficiency for international applicants at both undergraduate and graduate level. IELTS Academic is accepted as an equivalent alternative.
TOEFL MyBest Scores: UIUC's Graduate College and most undergraduate programmes accept TOEFL MyBest superscores. Confirm the specific policy with your college, since some professional and specialised programmes require a single-sitting score.
UIUC TOEFL Requirements by College
College of Liberal Arts and Sciences (LAS)
| Requirement | Detail |
|---|---|
| University-wide minimum | 79 iBT (undergraduate) |
| Recommended competitive floor | 100–102 iBT |
| Competitive score | 100–115 among admitted international students |
| Notes | LAS houses a broad range of majors from Economics to Biology; requirements are largely the university-wide baseline |
Grainger College of Engineering
| Requirement | Detail |
|---|---|
| Minimum TOEFL | 79–102 iBT depending on programme |
| Per-section guidance | No section typically below 20–21 |
| Competitive score | 100–115 |
| Notes | Graduate programmes (MS/PhD) generally expect scores toward the top of this range, especially for funded research positions |
Siebel School of Computing and Data Science (within Grainger)
| Requirement | Detail |
|---|---|
| Minimum TOEFL | Same as Grainger university floor (79–102 iBT) |
| Competitive score | 105–118 |
| Notes | Formerly the Department of Computer Science, renamed the Siebel School of Computing and Data Science in 2024 following a major gift from alumnus Thomas Siebel. UIUC CS is one of the most selective and highly ranked CS programmes in the US; the effective competitive bar for admitted international students runs well above the published minimum |
Gies College of Business
| Requirement | Detail |
|---|---|
| Minimum TOEFL (undergrad) | ~79–100 iBT |
| Minimum TOEFL (MS programmes) | ~100–102 iBT |
| Competitive score | 100–113 |
| Notes | Gies's direct-admit undergraduate business programme and popular MS in Business Analytics/Accountancy tracks are highly competitive for international applicants |
UIUC TOEFL Requirements — Summary Table
| College | Typical Min Overall | Competitive Score |
|---|---|---|
| Liberal Arts and Sciences (LAS) | 79 (undergrad) | 100–115 |
| Grainger College of Engineering | 79–102 (varies) | 100–115 |
| Siebel School of Computing and Data Science (Grainger) | 79–102 (varies) | 105–118 |
| Gies College of Business | 79–102 (varies) | 100–113 |
UIUC's official general range for undergraduate admission is commonly cited as 79–102 iBT; the specific floor and recommended score vary by college and programme level. Always confirm current thresholds directly with the college you are applying to.
TOEFL Per-Section Strategy for UIUC
Writing and Speaking — Especially for Teaching Assistantships
Graduate applicants hoping to be considered for Teaching Assistant (TA) positions typically need a strong Speaking subscore, since UIUC — like most large US research universities — applies a separate oral English proficiency check for international students before they can be assigned teaching duties. This matters specifically for funded PhD and some MS positions in Engineering and LAS departments; confirm the current departmental threshold directly, as it can vary by programme.
Target: Speaking 26+ if TA funding is a goal; Writing 24+ across all competitive programmes.
Computer Science Applicants — All Sections
Because UIUC CS is one of the hardest CS admits in the country for international students, admitted applicants typically present balanced, high scores across all four sections rather than a strong overall total carried by one section.
Target: No section below 24 for competitive CS applications.
Reading and Listening
A competitive UIUC application in any college should show Reading and Listening scores of 25+.
Minimum vs. Competitive at UIUC
UIUC's official general floor (79 undergrad; up to 102 in some graduate programmes) is significantly below what successful applicants to the university's most competitive programmes actually present. Competitive applicants typically score:
- Computer Science (undergrad and MS): 105–118
- Grainger Engineering (MS/PhD, funded): 100–115
- Gies Business (MS programmes): 100–113
Rule of thumb: Treat 79 as a bare minimum to be eligible for review, not a competitive target. Aim for 100+ broadly, and 105+ specifically for Computer Science.
TOEFL vs. IELTS for UIUC
UIUC treats TOEFL and IELTS as broadly equivalent. The choice generally comes down to preference and test-centre access.
| Feature | TOEFL iBT | IELTS Academic |
|---|---|---|
| Format | Fully computer-based | Computer + face-to-face or video Speaking |
| Speaking | Recorded responses | Live examiner interview |
| Score range | 0–120 | 0–9 (half-band increments) |
| Results | 4–8 days | 3–5 days (online) |
| MyBest / Superscore | Generally accepted | N/A |
Score Validity at UIUC
TOEFL scores are valid for two years from the test date. UIUC requires scores to be valid at the time of application.
How to Prepare for a UIUC-Level TOEFL Score
Reaching 100–118 requires solid, consistent performance across all four sections, with particular attention to Computer Science and Engineering benchmarks.
Speaking (target 24–30, 26+ for TA eligibility):
- Use the full response time and structure answers clearly
- Practise integrated tasks that summarise short lectures accurately
Writing (target 24–30):
- Independent task: build a clear, well-supported argument with specific examples
- Integrated task: accurately connect the lecture's points to the reading passage
Reading and Listening (target 25–30):
- Practise with authentic STEM and academic passages, since Grainger and CS applicants are often evaluated against a technically literate applicant pool
- Focus on inference and detail questions specifically
Common Mistakes UIUC TOEFL Applicants Make
Treating 79 as a target instead of a floor. The published minimum is designed to filter out clearly underprepared applicants — it is not remotely competitive for Grainger, CS, or Gies.
Ignoring the TA Speaking threshold. Graduate applicants seeking funded positions who score below the Speaking threshold may be admitted but denied TA eligibility, which can affect the feasibility of full funding.
Underestimating CS-specific competitiveness. UIUC Computer Science is regularly ranked among the top CS programmes in the US; applicants sometimes apply with scores that would be competitive elsewhere but fall short here.
A UIUC TOEFL score in the competitive range (100+, and 105+ for Computer Science) removes English proficiency as a concern and lets the strength of the rest of a STEM-focused application carry full weight.
