Learn How to Become an Illinois Certified Court Interpreter

Becoming a Certified Court Interpreter in Illinois involves several steps to ensure you meet the state's requirements for professional interpretation in legal settings. Here’s a step-by-step guide to help you navigate the process:


Step 1: Determine Eligibility

To become a Certified Court Interpreter in Illinois, you must meet the following basic requirements: ✔ Be at least 18 years old
✔ Have a high school diploma or equivalent
✔ Be authorized to work in the U.S.
✔ Have proficiency in English and the target language


Step 2: Register with the Illinois Court Interpreter Certification Program

Illinois follows the Consortium for Language Access in the Courts (CLAC) certification process, managed by the Administrative Office of the Illinois Courts (AOIC).

  • Visit the AOIC website and submit an application to participate in the certification process.

Step 3: Complete the Mandatory Court Interpreter Orientation

All candidates must attend a Court Interpreter Orientation program.
This orientation covers:
📌 Ethics & professional conduct

Step 4: Pass the Written Exam

After completing orientation, you must take the Written English Proficiency Exam, which tests:

Step 5: Take and Pass the Oral Proficiency Exam

Candidates for certification must take the Oral Court Interpreter Exam, which assesses:

🗣 Consecutive Interpretation – Listen, pause, then interpret
📄 Sight Translation – Read & translate legal documents aloud

Passing Score: Generally, a minimum of 70% in each section is required for certification.

For languages that do not have an oral exam, candidates may need to pass an alternative proficiency assessment.


Step 6: Complete a Background Check

Some jurisdictions require a criminal background check before final certification.
