Is high diploma online recognize by 50 states?

Answer 1

I believe the questioner meant: "Is an online high school diploma recognized in all 50 states?"

And the answer is that whether or not the high school diploma was earned online or in the classroom is not the issue. The issue is whether or not the high school is accredited by an agency approved by the US Department of Education (USDE); and, even more specifically, whether said agency is one of the US's six big USDE-approved "regional" accreditors (in other words, whether it's "regionally" accredited).

Employers, colleges/universities and government agencies will not recognize a high school diploma -- regardless of whether it's of the online or in-classroom type -- unless the school that issued it is "regionally" accredited. Period.

Yes, there's such a thing as "national" accreditation that's also USDE-approved, but at the high-school level, only "regional" accreditation will do.

At the college level, it's a different story: At that level, "national" accreditation, as long as it's either USDE-approved, or approved by the USDE-sanctioned Council for Higher Education Accreditation (CHEA), can be okay. But even at that level, "regional" accreditation is still better. And at the high school level, "national" accreditation isn't good enough; only "regional" accreditation, again, will do.

So the bottom line answer to the question is yes, an online high school diploma is recognized in all 50 states exactly the same as an in-classroom high school diploma; however, in either case, the school from which it came must be "regionally" (and not "nationally") accredited.
