A Guide When Looking for the Best Accredited Online High School

October 5, 2025

Students and families enjoy the freedom and flexibility that comes with an online high school program. The many benefits of online learning can be enticing, and the first step in selecting the right school is ensuring the program is accredited. 

Accredited online high schools offer a challenging curriculum and equally supportive teachers and counselors to help students achieve academic success and prepare them for college or university.

Dwight Global Online School, an established, accredited online school whose mission is to ignite the spark of genius in every student, is ranked #1 online high school in the Americas. 

What is Accreditation?

Accreditation is a status distributed by accrediting agencies that qualifies the academic institution as meeting educational standards for post-secondary education preparation. Accreditation is the standard by which many schools confirm that an acceptable learning program is being offered to students.

The best accredited online high schools maintain accreditation status to uphold a positive reputation and credibility among prospective students and families, as well as college and universities.

“Accreditation underscores the rigor and college-preparatory experience provided by Dwight Global to all our students,” said Megan Miller, Director of College Counseling. “Accreditation is also crucial for college admissions. Accreditations are always highlighted in the school profile, a snapshot of a school’s mission and philosophy, along with academic and extracurricular offerings. Colleges and universities rely on school profiles to understand the quality and vastness of the educational opportunities and resources available to our students”  

Understand How Schools Are Verified 

Accreditation is a voluntary process for educational institutions. Those that seek to obtain–and maintain–accreditation status undergo regular, rigorous reviews. 

High school accreditations with Cognia, for example, are renewed every six years. There is also a continuous cycle that includes self-assessment and an external review process. While the full accreditation cycle is every six years with Cognia, schools are also monitored annually and must complete evaluations throughout the term to ensure they are meeting Cognia’s Performance Standards.

Within the U.S., there are six accrediting agencies:

• New England: New England Association of Schools and Colleges
• Middle States: Middle States Association of Colleges and Schools
• North Central: North Central Association of Colleges and Schools (now part of Cognia)
• Southern: Southern Association of Colleges and Schools (now part of Cognia)
• Western: Western Association of Schools and Colleges
• Northwest: Northwest Accreditation Commission (now part of Cognia)

Ensure an Online High School’s Accreditation

Confirming a school’s accreditation gives students and families peace of mind. It is possible–and important–to check an institution’s accreditation by using the U.S. Department of Education’s Database of Accredited Postsecondary Institutions. Each school’s website should indicate their accreditation status, as well. 

What is the Difference Between an Accredited School vs. Non-Accredited?

The key difference between accredited online high schools and non-accredited high schools is the evaluation. Accredited online high schools must pass regular external evaluations to ensure that the standard of the learning program is acceptable for post-secondary education preparation. Having a credible, third-party organization to evaluate a school is what sets accredited online high schools apart from the rest.

At an accredited online high school like Dwight Global, families can be certain that their student’s academic future is set up for success. For those interested in college or university, accreditation is essential. The College Board requires a course audit of all high schools wanting to offer AP courses, advanced college-level high school courses that allow students the chance to receive credit from a college or university. Accreditation is also critical for anyone seeking financial aid. Students seeking federal aid and grants in college must graduate from an accredited high school.

With an accredited online high school, prospective students and families can expect experienced faculty and school leadership, rigorous academics, and a strong school community.
