Legacy Online School is fully accredited by the Western Association of Schools and Colleges (WASC), a distinction that underscores our commitment to high standards of excellence in education.
According to the National Center for Education Statistics, almost 21% of U.S. students choose online high schools.
That change is a bigger trend in American education: online learning is still a big part of how students finish their classes, because students want more control over their schedule and the chance to keep learning even when there are tough situations, like health issues.
But studies show that results from online high schools can be very different from one another. When looking at hundreds of online programs across the country, graduation rates are usually lower than in traditional public schools.
That’s why parents should take the time to carefully choose the right school. We understand how confusing this process can be, so teachers from Legacy Online School have identified the main point parents should focus on to avoid making mistakes.
An accredited online high school is a virtual secondary school that has been officially checked and approved by a known accrediting organization. In the United States, accreditation is the factor that determines whether kids can use their diplomas after the learning process. For example, in other institution or at work. Most U.S. colleges and universities require applicants to hold a diploma from an accredited high school. Without accreditation, colleges may:
Reject a diploma
Refuse to accept transferred credits
Require additional placement testing or remediation
Federal student aid programs are also tied to enrollment histories from accredited institutions.
The rapid growth of online education has also led to an increase in unaccredited and misleading programs. Accreditation acts as a safeguard against:
Diploma mills
Credit-for-pay schemes
Programs that lack real instruction or assessment
The National Center for Education Statistics (NCES) says that over 4.7 million U.S. students were taking part in distance or virtual learning programs in recent years, and online high schools have become a daily part of the education system. But results can be very different — that’s why how you choose is really important.
Accreditation should be non-negotiable. In the U.S., schools should be accredited by agencies recognized by the U.S. Department of Education. Regional accreditation is generally the most widely accepted by colleges and universities.
A strong online high school should be transparent about student outcomes. For context, the average four-year graduation rate for U.S. public high schools is about 87%, according to NCES.
When evaluating a school, look for:
Published graduation rates
College acceptance or enrollment statistics
Evidence that graduates attend accredited colleges and universities
High-quality online high schools typically offer:
Honors or Advanced Placement (AP) courses
College-prep or dual-enrollment options
Clear alignment with state or national academic standards
Freedom In planning is one of the biggest reasons families choose online school, but without support it doesn’t work for most students.
Research and national reporting consistently show that student support services are a major factor in online learning success. Look for programs that provide:
Academic advisors or counselors
Access to certified teachers
Tutoring or progress monitoring
Independent platforms like Niche compile data from the U.S. Department of Education along with parent and student feedback to rank online high schools nationwide. While no ranking is perfect, these tools help identify schools that consistently perform well across multiple metrics.
Pay attention to patterns:
Do parents mention strong teacher engagement?
Do students feel prepared for college?
Are concerns recurring or isolated?
The difference between online high schools goes beyond course lists. How lessons are delivered influences how students stay engaged and perform academically, making the learning model a key factor to consider. Here’s what our experts believe you should consider when evaluating the programs and formats offered by a school.
Asynchronous online high schools allow students to complete coursework on their own schedule. Lessons and assessments are available on demand, with deadlines set weekly or by semester.
This is the most common online learning format in U.S. K-12 education. NCES data shows that the majority of virtual secondary programs rely primarily on asynchronous instruction due to scalability and flexibility.
This type of programs is best for independent learners, students balancing athletics, work, health needs, or international schedules.
Synchronous programs have a planned schedule with real–time classes led by teachers, similar to a regular schoolday but happening online.
Reports from across the country show that programs with consistent live classes and instant interaction usually have better participation and remember more information than those that are completely on your own schedule.
These programs are great for students who need a structured approach and instant feedback as they go.
Blended programs combine asynchronous coursework with scheduled live sessions or teacher check-ins. This model has grown rapidly as schools respond to outcome gaps in fully self-paced programs.
Education research indicates that hybrid online models outperform fully asynchronous programs in student persistence and course completion.
This type of programs is best for students who want flexibility but still need guidance and oversight.
Online high schools typically offer:
Full-time diploma programs, where students earn all credits online
Part-time or single-course enrollment, often used for credit recovery or supplemental coursework
NCES reports that part-time online enrollment is increasingly used by students already enrolled in traditional schools, especially for AP or scheduling conflicts.
The cost of accredited online high schools varies widely depending on whether the school operates within the public education system or as a private institution. In 2025, families can choose between tuition-free public options and paid private online schools.
| School Type | Typical Annual Cost (USD) | Accreditation | Diploma Recognition | Who Covers the Cost? |
| Public Online High School | $0 | State-approved | Fully recognized public diploma | State funding |
| Online Charter High School | $0 | State-approved | Fully recognized public diploma | State funding |
| Private Accredited Online High School | $4,000–$12,000 | Regional or national | College- and NCAA-dependent | Family |
| Premium Private Online Programs | $12,000–$25,000+ | Regional | Widely recognized | Family |
Regardless of cost, accreditation remains the most critical factor. Colleges and universities evaluate online high school diplomas based on recognized accreditation. Families comparing costs should always verify accreditation status before enrollment to ensure credits and diplomas are accepted for postsecondary education.
Accreditation is the primary mechanism used to verify the quality and legitimacy of a school’s curriculum and credentials. Here are the benefits of such schools:
