Here's a breakdown:
* Accredited Diploma: This diploma signifies that the high school granting it has been evaluated and approved by a recognized accrediting agency. These agencies ensure the school meets specific standards in areas such as curriculum, teaching quality, facilities, and financial stability. An accredited diploma is generally more widely accepted by colleges and universities and employers. It provides assurance that the education received met a certain level of quality.
* Regular/Non-Accredited Diploma: A diploma from a non-accredited school means the school hasn't undergone this rigorous evaluation process. The quality of education can vary significantly. Colleges and universities may not accept these diplomas, or they might require additional testing or coursework. Employers might also view them less favorably. The value of the diploma is less certain.
In short: Accreditation provides a level of quality assurance that a non-accredited diploma lacks. While a "regular" high school diploma might be legitimate, its value is considerably diminished without accreditation. It's crucial to check if a school is accredited before enrolling to avoid potential issues later.
