Every year, Niche asks students and parents what their school is like, then weighs their answers against national education data. In the Niche 2027 rankings, that combination places Crimson Global Academy (CGA) at #2 Best Private Online High School in America, up from #5 last year. It also makes CGA the highest-ranked co-educational school on the list.
The Crimson Global Academy Niche ranking rests on a year of hard work from our students and teachers, and on 209 reviews from the community that knows CGA best. It’s their achievement as much as ours.
The rest of this year’s rankings, released on 25/09/2026, show the same progress, including a move up to #5 in America for STEM and three #1 rankings in Florida. The table below has the full picture, and the sections after it explain what each result means for your child.

#2 in Niche’s Best Online Private School Rankings, and the Highest Ranked Co-Ed School
What should a great online school actually be judged on? This year, for the first time, Niche answered that with a methodology built specifically for private online high schools, using factors designed around online instruction. Niche’s best online high schools rankings now list public and private schools separately, and under the new measures, CGA has moved from #5 to #2. The one school ranked above us is girls-only, which makes CGA the highest-ranked co-educational school on the list.
That matters to us because online isn’t a version of something else at CGA. It’s what the school was built for from day one. Students are placed by ability rather than age, and every live lesson is recorded so it can be revisited. Families pick the format that fits their week, whether that’s live group classes, 1:1 Da Vinci courses, or CGA Flex, our asynchronous option.
Best STEM High Schools in America 2027: CGA Ranks #5
At CGA, a student can start AP biology as soon as they’re ready for it, whatever their age or year group. It’s how we approach maths and science across the school, with students moving into Advanced Placement (AP) courses, A Levels, and International GCSEs when they’re ready rather than when their age says so. Some start very early. Read how Xander scored a 5 in AP Biology at 10.
This year’s Niche rankings add to that picture. CGA has moved up to #5 of 8,963 schools in Niche’s Best High Schools for STEM in America, from #6 last year. For the exam results, see our 2026 AP results.
Top 10 in Niche’s New College Prep Ranking
★★★★★
Our son joined CGA during his junior year. He is now a graduating senior attending his first choice school, NYU. Besides his work ethic and discipline, I attribute a significant part of his success to the rigors of the academics including all the options for AP classes, interesting electives as well as other opportunities such as virtual work internships and research. He has met students from all over the world and the administrators and faculty have been extremely responsive and supportive throughout his time here. Certainly an online education is not for everyone. As the world has become more global and requiring our workforce to also be more virtual, believe an online high school education with a global school reach can be a great fit and extremely beneficial for more and more students.
Parent, Niche review
Helping each student reach the university that’s right for them is what college prep is for, and this year Niche recognised CGA for it. For 2027, Niche has split College Prep into separate public and private lists, and CGA enters the new Best College Prep Private High Schools in America at #10 of 3,986, with an A+ for College Prep.
It comes in CGA’s most successful admissions cycle to date. In 2026, CGA students received 325 offers from more than 190 universities across the US, UK, Europe, Canada, and Australia, double the previous year. University counselling starts early and stays personal, so each student’s applications are built around where they actually want to go. See the full 2026 admissions results.
#1 in Florida Across Three Niche Rankings
Florida is where Crimson Global Academy, USA is based, in Orlando, and it’s where CGA’s Niche results are strongest.

- #1 of 548 Best High Schools for STEM in Florida
- #1 of 273 Best College Prep Private High Schools in Florida

Among Niche’s Best High Schools in America
This is the ranking that measures CGA against private high schools across the whole country, online or on campus. CGA is #23 of 4,672 in Niche’s Best Private High Schools in America. Online isn’t a separate category here, and it doesn’t need to be. It’s simply how CGA delivers its education.
A Global Classroom, Graded A+ for Diversity
In a single CGA class, a student in Florida might be working through a problem with classmates in Tokyo and Dubai. Niche’s new standalone Most Diverse Private High Schools ranking reflects the range of places and backgrounds students come from, and CGA ranks #22 of 5,273 nationally, with an A+ for Diversity. Many of those friendships carry on offline, at regional meet-ups and school camps.
★★★★★
Our daughter attends CGA full-time following the UK curriculum, which offers a rigorous, knowledge-rich pathway setting students up well for university and beyond… She has made great friends at CGA and is always in contact with them, as well as in-person meet-ups, camps and events that are organised by the school to facilitate face-to-face meetings. Meeting like-minded friends and sharing classes with students from other countries has been really enjoyable and valuable, she feels part of a community, a family…Parent, Niche review

★★★★★
Switching to Crimson Global Academy for junior year was a transformative “leap of faith” for our son, a competitive rower and dedicated student. CGA’s flexibility allowed him to balance rigorous academics and science research with a demanding athletic schedule. The expert, international faculty bring real-world passion to the “rich tapestry” of his education.
Beyond the curriculum, he gained a competitive edge in digital fluency - mastering Zoom and collaborative platforms essential for the modern workforce. With recorded classes and supportive administrators accommodating his competitions, he never falls behind. CGA perfectly balances high-level intellectual pursuits with the freedom to excel outside the classroom.
Parent, Niche review
★★★★★
As a transfer student from an IB program, Crimson was very flexible and allowed me to transfer into a few AP classes, helping me in my academic goal. They have been very supportive in scheduling my classes and want me to be able to have the best profile possible so I can get into good universities. They hire excellent teachers and tutors and are easy to contact. They support questions and create a safe learning environment.
