How to Verify Illinois School Accreditation

Illinois accreditation landscape

Illinois has a layered accreditation system that varies by institution type. Understanding which body governs each type is the first step in verification:

• Public and private degree-granting colleges and universities — accredited by the Higher Learning Commission (HLC), one of the seven regional accreditors recognized by the US Department of Education. HLC covers 19 states in the Midwest, including Illinois. The University of Illinois system, Northwestern, DePaul, Loyola Chicago, Illinois State, and hundreds of other institutions hold HLC accreditation.
• Public K-12 schools — operated under the Illinois State Board of Education (ISBE). Illinois public K-12 schools do not hold independent "accreditation" in the same sense as higher education; they operate under ISBE oversight and may seek voluntary accreditation through Cognia (formerly AdvancED) or the Illinois State Accreditation process.
• Private K-12 schools — not required to obtain state accreditation in Illinois, though many voluntarily seek accreditation through Cognia or the Independent Schools Association of the Central States (ISACS), an NAIS affiliate.
• Private postsecondary schools (non-degree) — cosmetology schools, trade schools, and other non-degree postsecondary programs are regulated by IBHE and must hold IBHE approval to operate in Illinois.
• Online institutions operating in Illinois — must hold regional accreditation (typically HLC) and comply with IBHE's out-of-state institution approval requirements under the State Authorization Reciprocity Agreement (SARA).

Verifying Illinois colleges and universities: HLC

The Higher Learning Commission is the regional accreditor for Illinois higher education. Its accreditation is recognized by the US Department of Education and required for students to receive federal financial aid. HLC-accreditation is the baseline for any legitimate Illinois college or university.

How to check HLC accreditation

1. Go to hlcommission.org and navigate to "Institutional Accreditation" → "Institutional Directory."
2. Search by institution name or state (select Illinois) to find the school's record.
3. Confirm the accreditation status: Accredited, Accredited — On Probation, or Accredited — Show Cause. Probation and Show Cause are warning statuses that indicate the institution is under scrutiny for failing to meet HLC standards.
4. Note the next comprehensive evaluation date and any current sanction details.

Major Illinois institutions in HLC's database

All of Illinois' flagship public universities hold HLC accreditation: University of Illinois Urbana-Champaign, University of Illinois Chicago, University of Illinois Springfield, Illinois State University, Northern Illinois University, Southern Illinois University Carbondale, and SIU Edwardsville. Major private institutions including Northwestern University, University of Chicago, Loyola University Chicago, DePaul University, and Illinois Institute of Technology also hold HLC accreditation. If an Illinois institution claiming college-level status is not found in HLC's directory, treat it as unaccredited.

Verifying private postsecondary schools: IBHE

The Illinois Board of Higher Education (IBHE) maintains oversight of private postsecondary institutions and out-of-state institutions serving Illinois students. Private career and vocational schools in Illinois must obtain IBHE approval under the Private Business and Vocational Schools Act.

How to verify IBHE approval

1. Visit ibhe.org and search the database of approved private postsecondary institutions under the "Private Colleges & Universities" or "Non-Degree Granting Institutions" sections.
2. Confirm the school holds current IBHE approval for the program of study in question.
3. For closed institutions, IBHE maintains records and can direct student records requests to the appropriate archive.

An Illinois private school claiming to issue certificates or degrees that is not found in IBHE's database is operating outside regulatory requirements. Credentials from such institutions should not be accepted as legitimate.

Verifying Illinois K-12 schools

For high school diploma verification from Illinois public or private secondary schools:

Public K-12: ISBE School Finder

The Illinois State Board of Education maintains a public school directory at isbe.net/Pages/Illinois-School-Report-Card.aspx. Use the ISBE school finder to confirm a public school's existence, district affiliation, and operational status. Illinois public high schools issue diplomas upon completion of state-required coursework; verification of an individual diploma goes through the high school's registrar or the district administration office.

Private K-12: ISACS and Cognia

Illinois private K-12 schools are not required to hold state accreditation, but many voluntarily seek accreditation through:

• ISACS (Independent Schools Association of the Central States) — accredits independent schools in Illinois and surrounding states. Verify member school status at isacs.org.
• Cognia (formerly AdvancED/North Central Association) — accredits both public and private K-12 schools nationwide, including many in Illinois. Search the Cognia school locator at cognia.org.
• ISBE's voluntary accreditation — Illinois offers a state accreditation process through ISBE for schools that seek formal state recognition.

For high school diploma verification, regardless of accreditation status, always contact the school's registrar directly. Illinois public school records more than seven years old may be archived with the district or ISBE.

Illinois-specific diploma mill patterns

Illinois — particularly Chicago — has historically been a hub for diploma mill activity given its large population and reputation as a business center. Common patterns to watch for:

1. Institutions using "Chicago" or "Illinois" branding without HLC accreditation — names designed to mimic the University of Illinois, University of Chicago, or Northwestern. Always verify the full institutional name in HLC's directory. Confusingly similar names (e.g., "Illinois University Online," "Chicago Institute of Technology") may not correspond to any accredited institution.
2. Private postsecondary schools not listed in IBHE's database — a certificate-issuing school in Illinois not found in IBHE records is unregulated. Vocational and cosmetology program credentials from unlisted schools should not be accepted.
3. Institutions claiming ACICS accreditation after 2016 — the Accrediting Council for Independent Colleges and Schools (ACICS) was terminated by the US Department of Education in 2016, then reinstated with conditions in 2018. A number of Illinois for-profit colleges closed during the ACICS termination period. Verify whether the specific institution's ACICS accreditation was active during the claimed enrollment period.
4. Closed for-profit colleges — Illinois saw significant closures of for-profit institutions affiliated with Westwood College, Sanford-Brown College, and Robert Morris University Illinois. Degrees from closed Illinois institutions are still verifiable through IBHE or ISBE records — contact those agencies to locate archived student records.
5. Online institutions claiming HLC accreditation without appearing in HLC's directory — a common fraud pattern is claiming regional accreditation status that was never granted. Always verify against HLC's institutional directory, not the school's website.
