The Michigan Seal of Biliteracy (MI-SoBL) recognizes high school graduates who show proficiency in English and at least one other world language. Michigan is notable for a heritage-friendly pathway: students can prove the second language either by assessment or by documented schooling in that language. This guide covers the requirements, the proficiency level, the accepted assessments, and how students earn it.

What the Michigan Seal of Biliteracy Is
Quick answer: the Michigan Seal of Biliteracy is awarded to graduates who demonstrate proficiency in English and in a language other than English (a LOTE). English is shown by completing the Michigan Merit Curriculum and any district requirements; the second language is shown by reaching Intermediate High on an approved assessment, or by documented schooling in that language.
Michigan Seal of Biliteracy by the Numbers
Michigan’s program is growing fast, and the Michigan Department of Education published fresh numbers in April 2026.
| Metric | Figure |
|---|---|
| Graduates earning the seal in 2024-2025 | 2,797, a record |
| Prior year (2023-2024) | 2,253 |
| First full year (2018-2019) | 1,164 |
| Top languages (2024-25) | Spanish (1,817), Arabic (266), French (94) |
The trajectory matters more than the absolute numbers: awards have more than doubled since the first full year, and Arabic’s strong second place reflects Michigan’s communities in a way few other state programs do. For districts, the growth means colleges and employers in the state see the credential more often each year.
Michigan Requirements
| Area | How to meet it |
|---|---|
| English proficiency | Complete the Michigan Merit Curriculum (MMC) graduation requirements, plus any individual district requirements. |
| Other-language proficiency | Reach at least Intermediate High (ACTFL) across all domains on an approved world-language assessment; OR provide school records showing education to at least grade 6 in the language. |
The schooling-record option is especially useful for immigrant and heritage students who were educated in the language but may not have a test score.
Accepted Assessments
Michigan accepts a range of proficiency and performance assessments appropriate for grades 9 to 12, including:
- AAPPL (ACTFL Assessment of Performance toward Proficiency in Languages);
- the ACTFL Oral Proficiency Interview (OPI);
- the ACTFL Writing Proficiency Test (WPT); and
- other approved commercial assessments on the state’s list.
Most languages are assessed across four domains: listening, speaking, reading, and writing.
How to Earn It in Michigan
- Complete the Michigan Merit Curriculum and any district requirements for English.
- Reach Intermediate High on an approved language assessment, or submit records of schooling to grade 6 or higher in the language.
- Your district awards the seal at graduation.
The Michigan Department of Education recommends testing from the second semester of junior year through the first semester of senior year, so plan the assessment window early.
Benefits in Michigan
The seal signals college- and career-ready bilingualism, strengthens applications, and formally recognizes the languages of Michigan’s multilingual communities. Many colleges accept it toward world-language credit or placement, and the heritage-schooling pathway makes it accessible to students whose skills were built outside a traditional world-language course.
The Heritage-Schooling Pathway in Detail
Michigan’s most distinctive feature is that it lets students prove the second language in two very different ways: by assessment or by documented schooling. Under state policy, a student can meet the other-language requirement either by reaching Intermediate High across the assessed domains on an approved world-language assessment, or by providing school records showing education to at least grade 6 in that language. The schooling-record option is designed for immigrant and heritage students who were educated in the language abroad but may not have a standardized test score in it.
This dual pathway changes how families should plan. A heritage student with transcripts from schooling in the language may be able to document eligibility without sitting a proficiency exam at all, which is faster and avoids a testing fee. A student without those records, or one whose home language was learned informally rather than in school, will generally need the assessment route and should plan for it. Confirming early which documentation a district accepts prevents a late scramble to locate school records or register for a test.
Planning Around the Testing Window
For students taking the assessment route, Michigan’s recommended testing window is narrow: the Michigan Department of Education recommends testing from the second semester of junior year through the first semester of senior year. Because the AAPPL and similar assessments are offered only on limited dates, and because the seal requires Intermediate High across the assessed domains, students benefit from identifying test dates in grade 11 and confirming registration well ahead. A student who is close to Intermediate High but not quite there should build targeted speaking and listening practice before the window opens, since the runway to retake within that window is short. Completing the Michigan Merit Curriculum and any district requirements satisfies the English side, so most of the planning effort belongs on the world-language assessment timing.
Frequently Asked Questions
What are the Michigan Seal of Biliteracy requirements?
Complete the Michigan Merit Curriculum for English, and reach Intermediate High (ACTFL) in a second language on an approved assessment or show schooling to at least grade 6 in that language.
What proficiency level is needed?
At least Intermediate High on the ACTFL scale across the assessed domains in the language other than English.
Which assessments does Michigan accept?
The AAPPL, ACTFL OPI and WPT, and other approved commercial assessments; testing is recommended from second semester junior year to first semester senior year.
Can heritage speakers qualify without a test?
Yes. Documented schooling to at least grade 6 in the language is an accepted way to demonstrate proficiency.
What documented schooling qualifies without a test?
School records showing education to at least grade 6 in the language can demonstrate the other-language proficiency, an option designed for immigrant and heritage students educated in the language abroad. Confirm with your district which records it accepts.
When should I take the language assessment?
The Michigan Department of Education recommends testing from the second semester of junior year through the first semester of senior year. Because test dates are limited and the runway to retake is short, register early.
How is the English requirement met in Michigan?
By completing the Michigan Merit Curriculum graduation requirements plus any individual district requirements. Most of the planning effort therefore focuses on the world-language side.
How many students earn the Michigan Seal of Biliteracy?
2,797 graduates earned it in 2024-2025, a record, up from 2,253 the year before and 1,164 in the first full year (2018-2019), according to the Michigan Department of Education.
Which languages are most awarded in Michigan?
Spanish leads by far (1,817 in 2024-25), followed by Arabic (266) and French (94). Any language with an approved assessment can qualify.

The Narrow Window to Reach Intermediate High
Michigan asks for Intermediate High across all four domains, and the state recommends testing in a window that runs only from second-semester junior year through first-semester senior year. That is a short runway. A heritage student may speak the language comfortably at home yet still need to sharpen the oral proficiency the AAPPL or OPI actually measures before the window closes.
The obstacle is practice time, not talent. Moving a domain up a full ACTFL level takes many hours of spoken interaction with feedback, and one world-language teacher cannot supply that individually to a roomful of students preparing for the same assessment. The schooling-record pathway helps some, but students testing their way in need reps the school day does not contain.
So some Michigan districts are adding practice students can do on their own schedule. Telo AI is one example, providing adaptive conversation and feedback through separate English, Spanish, and French apps calibrated toward the level the seal expects.

With enough practice before the window opens, the assessment confirms a proficiency students already own rather than one they are scrambling to reach. A seal earned that way marks a durable skill, which is the whole point of certifying biliteracy in the first place.
