10 Best Online High Schools of 2026

Connections Academy is the first place to check if you want an online high school that costs nothing in tuition. Its schools are public, so state tax dollars pay for the education, and Connections Academy says there are no hidden costs. The program provides certified teachers, virtual classrooms for group lessons and 1:1 support, and the textbooks, workbooks and project materials each course needs. Connections Education is accredited by Cognia, and many of its individual schools also hold regional accreditation. The catch is availability: you can only enroll if your state has a Connections Academy-supported school, and the cost page points families in other states to Pearson Online Academy, the tuition-based private school from the same company. Families pay for standard supplies, optional field trip fees and internet service, and whether a computer or internet subsidy is included depends on state rules. Because it is a public school, expect state standards and the school's own enrollment windows.

Pearson Online Academy is the private, tuition-based sibling of Connections Academy, and it fills the gap for families whose state has no free option or who want more control over courses. Full-time high school tuition is $8,250 for the academic year, or $7,838 with the 5% pay-in-full discount, and the College and Career Readiness program is included. A student who joins for the second semester pays $4,850. Part-time high school courses cost $435 to $850 each, covering credit recovery, original credit, Honors and AP and NCAA-eligible courses, and summer school uses the same per-course model. The school says certified online teachers teach every class and that students can take classes anytime and from anywhere. The main drawback is price next to public online schools, and families on a monthly plan should note the $25 late fee and account suspension if a payment is more than 15 days late.

Acellus Academy is a fit for students who learn well from video and want to start right away: families create a parent account, pick courses and the student is enrolled immediately. Basic tuition is $249 a month, and the Roger Billings Scholarship, offered during enrollment, reduces it to $79 a month. Enhanced at $299 adds priority support, and Premium at $499 adds a locked-down student device that blocks web browsing. Every plan includes hundreds of course options, credits toward an accredited diploma, Vectored Instruction to fill gaps, and the Acellus Writing Tutor. The school is regionally accredited by WASC, its core high school courses are NCAA-approved, and its AP coursework is approved by the College Board. Families can cancel at any time, but payments already processed are not refunded, and a $100 graduation application fee is due at the end. Students who want live discussion with a teacher should look at Stanford OHS or K12 Private Academy.

Excel High School is a budget-friendly accredited option with a clear menu of plans. The High School Silver plan costs $1,950 a year, or 10 interest-free payments of $195, and covers 6 credits, the standard curriculum, the BRYTE AI Tutor and an Academic Coach Help Desk. Gold, at $2,500, raises the limit to 8 credits, adds a 24-credit graduation track and opens honors or California A-G courses; there are also NCAA and CA-AG plans at the same price. Platinum costs $4,900 and includes AP courses and Success Coach Pro. Single courses start at $325, and adults 18 and over can choose a $99 a month diploma path. In December 2025 Excel earned Accredited with Distinction status from Cognia, and its core courses are NCAA-approved. The trade-off is that learning is self-paced with coaching and an AI tutor, so students who want scheduled classes with a teacher should look elsewhere.

K12 Private Academy is the private, tuition-based school from Stride, the company behind the K12 curriculum. For the 2026 to 2027 school year, full-time high school tuition is $7,995, with or without the Career and College Prep option, though that option carries a $25 administrative fee and dual enrollment adds $750. Part-time students pay $1,350 per high school course for the year and can take up to three classes a semester, while full-time students can take up to six. The catalog lists more than 150 standard courses and nearly 40 electives, plus AP options. A team of subject-specific teachers, academic coaches and counselors supports each student, and teachers engage with students every week, often through live Class Connect sessions. Arizona families can use ESA funds, and several other states offer scholarships the school accepts. Families who mainly need a low price should compare the self-paced schools further down this list.

Penn Foster High School suits a learner who mainly wants to finish a diploma cheaply and on their own schedule, including adults returning to school. The program is priced as one fee rather than per year: $1,149 if you pay in full during the offer that ends November 30, 2026, or $1,639 on a monthly plan at $55 a month with $20 down. Each high school course you transfer in takes $20 off. Tuition covers digital textbooks, goal setting and progress tracking tools, unlimited student support and career services, and students can choose career-focused electives such as the HVAC and healthcare pathways. Penn Foster is nationally accredited by the DEAC and Cognia. Its own disclaimer says the diploma is a proprietary program and that acceptance by colleges and employers is up to each institution, so a college-bound teen should check with target schools first. It is a self-study program, not a school with scheduled classes.

The Keystone School suits homeschool families who want accredited courses without committing to a full private-school package. Full-year courses start at $400, semester courses at $289 and credit recovery courses at $169, and Keystone says full-time enrollment typically costs between $1,800 and $2,900 a year depending on grade and courses. Full-time students usually take five or six full-year courses. Every course includes access to certified instructors through a toll-free help line, with answers within one business day, plus record keeping and official transcripts. Keystone is fully accredited, NCAA approved, and offers family discounts, military discounts and a tuition assistance program. It is self-paced, so there are no scheduled live classes, and the school asks families to allow up to 72 hours after purchase for course access to activate. That makes it less suited to a student who needs daily structure from a teacher.

Laurel Springs is a strong fit for students whose schedules do not fit a school day, such as athletes or young performers, who still want a college-prep record. High school tuition is $11,700 a year or $6,450 a semester, and The Academy, a more collaborative path with live workshops and research, costs $17,250 for high school. Single high school courses run from $900 for P.E. to $2,200 for AP. Students choose from more than 240 college-prep courses, 160+ NCAA-approved courses and 60+ Honors and AP courses, and can take dual enrollment through Baylor and Syracuse. Coursework is asynchronous and mastery-based, so students can redo work and retake exams, and Tutor.com provides 24/7 tutoring in every subject. The school reports that 93% of students scored a 3 or higher on at least one AP exam. The cost is the drawback, and the IMPACT learning support program adds $3,000 to $7,500 a year.

Stanford Online High School is the choice for a strong student who wants a real classroom online: courses meet as small, live, discussion-based seminars, modeled on college seminar teaching. Its signature Philosophy Core combines philosophy, science, history and political theory. The school enrolls 1,092 students from 48 U.S. states and 55 countries, and it is an independent school within Stanford University for grades 7 to 12. Tuition is $31,900 a year for full-time students taking four or more courses, $19,140 for two or three courses, and $6,380 for a single course, which suits students who stay at their local school and add, say, college-level math. Books and materials add between $30 and $1,300. Stanford OHS offers need-based aid that can also cover books and some event tickets, but no merit scholarships, and admission requires an application. For most families the price and the application process rule it out.

Oak Meadow suits a self-directed teen who prefers books, projects and written feedback to video lessons. Its high school curriculum is secular and college-prep, with full four-year sequences in English, math, science and social studies plus electives such as Personal Finance and Forensic Science. Families can buy the curriculum for independent homeschooling or enroll in the accredited distance learning school, where students work one-to-one with teachers who give written assessments, narrative evaluations and grades. Enrolled pricing is per course: a full-year course costs $2,150 in tuition plus up to $285 to $759 in materials, and Oak Meadow puts four full-year courses at $8,250 to $9,620. Tuition includes teacher support and college counseling, and an interest-free FACTS payment plan is available for tuition of $900 or more, for a $50 fee. Because each course is priced separately, a full load costs as much as a private online school with scheduled classes.
