Terms of Study

There are four 8-week terms during the regular academic school year and one in Summer. Check out the complete term schedules. The terms begin in August, October, January, March, and May, making a total of five enrollment periods for the year.


Initial course placement into the seven five-level program is initially determined by your score on an internationally recognized English proficiency exam (such as the Duolingo test, TOEFL, IELTS, or equivalent). For admission to CESL's lowest level, English language proficiency must be at this level: TOEFL iBT 40, TOEFL ITP 425 or TOEFL PBT 425/IELTS 4.0/Duolingo English Test 75/CEFR B1. Placement once made is then verified by an internal Diagnostics Exam during the first day of class. We no longer offer each level every term so it is very important to know if your level will be open BEFORE you travel to Carbondale

Overview & detailed description of CESL Curriculum

The complete CESL program has five levels. The number of levels needed to complete the program is based on initial placement. All students receive in all levels 20 hours per week of intensive English language instruction. At each level, all language skills are treated in a “core” class meeting 10 hours per week. Additional instruction is provided at each level in two 5-hour classes that differ by level, as indicated below.

Average class size is 6-7 students, so there is a lot of interaction in each class between classmates and with teachers.

CESL Level Descriptions

Progression Through Program

Level Promotion Guidelines: (Effective October 2021)

The following conditions must be met to pass a level:

Levels* Grade Required**

Category: Advanced

AE 1
AE 2
80% grade or above in all classes

Category: Academic Preparation

EAP 1 80% grade or above in all classes
EAP 2 80% grade or above in all classes
GSE 80% grade or above in all classes

* All levels can be repeated a maximum of 2 times and can be taken a maximum of 3 times.

**A specific TOEFL score is not required for progression between any two CESL proficiency levels, but it is required that students take the CESL-offered TOEFL ITP in the EAP1, EAP2, and GSE levels, in consideration of the fact that SIU, as do other universities, requires minimum TOEFL scores of 520 and 550 (requirement can vary by school, college, or program) for entry into undergraduate and graduate degree programs, respectively.

CESL Completion Certificate:

Students will receive a completion certificate from CESL after passing all required levels:

  • If your goal is undergraduate studies, you must pass the EAP2 level to receive the certificate.
  • If your goal is graduate studies, you must pass the GSE level to receive the certificate.

Completing CESL does not guarantee admission to SIU. Students must apply and meet all SIU admission requirements (academic and language) to be eligible for admission. Please visit the Center for International Education (CIE) or the Graduate School office website for a complete list of admission requirements.

>SIU Campus


The student advisor plans orientation programs for each CESL term. These sessions explain topics such as safety, academic success, immigration, the opportunities available in Carbondale and SIU Carbondale. Organized extracurricular activities at SIU Carbondale, picnics, and parties are a regular part of life at CESL.


There are many affordable housing options. Explore SIU housing options online. Most students prefer living in student residence halls near campus. The approximate cost of room and board is indicated under the COST tab. 

We would be happy to email you information about housing or we can help you arrange living accommodations when you arrive.


A Certificate of Completion is awarded to students who successfully complete a CESL program at either the undergraduate or graduate level. A Certificate of Attendance can be issued reflecting the actual dates you attended. Transcripts of performance are mailed directly to an institution upon the request of the student. Unofficial student copies are also available.
