The Illinois Seal of Biliteracy is a state award for high school graduates who demonstrate a high level of proficiency in English and in at least one other language. Illinois was an early adopter, adding the award in 2014, and it carries a benefit few states match: automatic college credit. This guide covers the requirements, the exact proficiency level, the accepted assessments, the benefits, and how students earn it.

What the Illinois Seal of Biliteracy Is
Quick answer: the Illinois State Seal of Biliteracy is awarded by a school district or nonpublic school to graduating students who show a high level of proficiency in English and in at least one language other than English (a LOTE), demonstrated during grades 9 to 12. It appears on the student’s diploma and transcript, and it signals college- and career-ready bilingualism.
Illinois Seal of Biliteracy by the Numbers
Illinois launched its seal in 2016, and 2026 marks ten years of steady growth across the state.
| Metric | Figure |
|---|---|
| Participating districts | 116 (up from 80 in 2018) |
| Participating schools | 264 |
| Languages awarded | 26 (up from 17 in 2018), from Spanish and Polish to Malayalam and Wolof |
| Program anniversary | 10 years in 2026 |
| College credit | Illinois public universities must award course credit for the seal |
Two things stand out in the Illinois data. The linguistic diversity: 26 languages have been awarded, reflecting communities from across the state, not just the largest language groups. And the credit guarantee: Illinois is one of the few states where public universities are required by law to grant course credit for the seal, which turns the award into measurable tuition savings.
Illinois Seal of Biliteracy Requirements
Illinois sets two requirements: proficiency in English and proficiency in the other language.
| Requirement | How it is met |
|---|---|
| English proficiency | Meet the state’s English measures (for example, proficiency on the required state English/language arts assessment, or the equivalent for English Learners). |
| Other-language proficiency | A composite of Intermediate High (ACTFL Proficiency Guidelines 2012) or its equivalent, across all four domains: speaking, writing, listening, and reading. |
Intermediate High is a meaningful bar: the student can handle most everyday and many academic tasks in the language, not just memorized phrases.
Accepted Assessments
Students prove the second language with an approved assessment. The State Superintendent posts an updated list each year by July 1. Commonly accepted options include:
- AAPPL (ACTFL Assessment of Performance toward Proficiency in Languages): form B requires a score of I-5 (Intermediate High) across the four skills.
- AP world language and culture exams at a qualifying score.
- IB language exams at a qualifying score.
- DELE (Diploma de Espanol como Lengua Extranjera) and other approved standardized language assessments.
Because the accepted list and cut scores can change annually, confirm the current year’s list with your district or the Illinois State Board of Education before testing.
How to Earn It in Illinois
- During grades 9 to 12, take an approved assessment in the target language and reach the Intermediate High composite.
- Meet the English proficiency requirement through the state’s measures.
- Your district applies the seal to your diploma and transcript at graduation.
Heritage and bilingual students often already speak the language at home; the seal simply verifies and credentials it. Students still developing the language should build listening, reading, and especially speaking across the high school years.
The Commendation Toward Biliteracy
Illinois also offers a Commendation Toward Biliteracy, an interim recognition for younger students (for example, at the end of eighth grade or early high school) who are on the path to the full seal but have not yet reached Intermediate High. It keeps students motivated toward the graduation award.
Benefits in Illinois
Illinois offers one of the strongest benefits in the country: all Illinois public colleges and universities must accept the State Seal of Biliteracy as equivalent to two years of foreign language coursework and award course credit. Beyond credit, the seal strengthens college applications, signals bilingual skills to employers, and formally recognizes the languages of Illinois’s multilingual families.
Why the All-Domains Composite Matters in Illinois
Illinois sets its world-language bar at an Intermediate High composite across all four domains: speaking, writing, listening, and reading. This is a stricter structure than a single overall score, because a student cannot lean on a strong reading result to offset weaker speaking. On the AAPPL, for example, the standard route requires an I-5 (Intermediate High) result across the four skills. The practical implication is that planning should identify the student’s weakest domain early, since that domain, not the average, determines whether the composite clears the bar.
For most learners the limiting domain is speaking, which is the hardest to develop to Intermediate High and the one a course sequence tends to build least. Heritage speakers often face the reverse pattern, with strong speaking and listening but developing academic reading and writing. Either way, the composite structure rewards balanced proficiency, so students benefit from targeting the specific domain that is holding the composite down rather than practicing broadly.
The College-Credit Value in Concrete Terms
Illinois offers one of the strongest seal benefits in the country, and it is worth quantifying. State law requires every Illinois public college and university to accept the State Seal of Biliteracy as equivalent to two years of foreign-language coursework and to award course credit. For a student, that can mean skipping introductory college language courses entirely, which saves both tuition and time toward a degree. Because the accepted assessment list and cut scores are updated annually, with the State Superintendent posting the list by July 1 each year, students should confirm the current year’s approved assessments with their district or the Illinois State Board of Education before testing. The Commendation Toward Biliteracy, awarded to students rated at the Intermediate Low or Intermediate Mid range who have not yet reached Intermediate High, gives younger students an interim goal on the way to the full credit-bearing seal.
A Practical Calendar for Illinois Students
Illinois requires Intermediate High across domains, so the assessment window deserves planning rather than a senior-year scramble.
- Grades 9-10: confirm the district participates and target the Commendation Toward Biliteracy as a milestone. Heritage speakers should identify which of ISBE’s approved assessments covers their language.
- Grade 11: take a practice or first attempt at the chosen assessment (AAPPL, STAMP, AP, or another from ISBE’s approved list, which the state updates regularly). Aim to know your domain profile before senior year.
- Grade 12: final attempt scheduled early enough for a retake if one domain falls short. Districts report earners to ISBE and note the seal on the transcript, which unlocks the public-university course credit.
Frequently Asked Questions
What are the Illinois Seal of Biliteracy requirements?
English proficiency plus a composite of Intermediate High (ACTFL) or equivalent in another language, across speaking, writing, listening, and reading, demonstrated during grades 9 to 12 through an approved assessment.
What proficiency level is needed?
A composite of Intermediate High on the ACTFL scale in the language other than English. This is higher than the Intermediate Mid level some states require.
Does the Illinois seal give college credit?
Yes. All Illinois public colleges and universities must accept it as equivalent to two years of foreign language coursework and award credit.
Which assessments does Illinois accept?
Approved options include the AAPPL (form B, I-5), AP and IB world language exams, DELE, and other assessments on the state’s annual list. Confirm the current year’s list with your district or ISBE.
Who awards it?
Illinois school districts and nonpublic schools award the seal to qualifying graduates; it appears on the diploma and transcript.
Do I need Intermediate High in every domain?
Yes. Illinois requires an Intermediate High composite across all four domains: speaking, writing, listening, and reading. A strong score in one domain does not offset a weaker one, so the weakest domain effectively determines eligibility.
What is the Commendation Toward Biliteracy?
It is an interim recognition for students rated at the Intermediate Low or Intermediate Mid range, typically younger students on the path to the full seal, who have not yet reached the Intermediate High bar. It keeps students motivated toward the graduation award.
How much college credit does the Illinois seal grant?
State law requires Illinois public colleges and universities to treat the seal as equivalent to two years of foreign-language coursework and to award credit, which can let students place out of introductory college language courses.
How many districts participate in the Illinois Seal of Biliteracy?
116 districts and 264 schools in ISBE’s most recent public report, up from 80 districts in 2018, with awards spanning 26 languages. The program marks ten years in 2026 and participation has grown every year.
Which languages have been awarded in Illinois?
Twenty-six languages so far, including Spanish, Polish, French, German, Arabic, Mandarin, Cantonese, Czech, Malayalam, and Wolof. Any language with an ISBE-approved assessment can qualify, and the approved list is updated regularly.

Conclusion
The Illinois Seal of Biliteracy sets a clear, ambitious bar, Intermediate High in a second language, and backs it with real value: automatic college credit at every public university in the state. For heritage speakers it credentials a language they already have, and for language learners it rewards years of practice. Reaching it reliably comes down to consistent speaking and listening through high school.

A Higher Bar With Real College Credit on the Line
Illinois sets one of the steeper bars in the country: an Intermediate High composite across all four domains, not an average that a strong reading score can prop up. And because every public university in the state must grant two years of course credit for the seal, a student who falls a level short in speaking is not just missing a diploma sticker, they are leaving tuition credit on the table.
That makes the weakest domain decisive, and for most learners the weakest domain is speaking. Lifting it to a full Intermediate High composite takes sustained oral practice with feedback, and a single world-language teacher cannot deliver that individually to every student aiming for the seal in a given year.
So some Illinois districts are adding practice that targets the productive skills the composite depends on. Telo AI is one example, providing adaptive conversation and feedback through separate English, Spanish, and French apps calibrated toward the Intermediate High benchmark.

When speaking rises to meet reading and listening, the composite clears the bar and the college credit follows. A seal that converts into real tuition credit is worth reaching for, and reaching it comes down to practicing the domain that a classroom can least often provide.
