Accreditation is a process by which an external agency evaluates schools and other educational institutions to determine if they meet specific quality standards. Accreditation is important because it helps ensure that schools provide high-quality education to their students. Some colleges and universities require that students have a degree from an accredited school to be eligible for admission. Online schools can be accredited just like traditional schools. However, the accreditation process for online schools may be different, as the school may not have a physical campus or may have students located in other states or countries. Some online schools are accredited by regional accrediting agencies, recognised by the U.S. Department of Education and the Council for Higher Education Accreditation (CHEA). Other online schools may be accredited by national accrediting agencies, which the U.S. Department of Education and CHEA recognise. Therefore, it’s essential to research the accreditation of any school you are considering attending, whether it is an online school or a traditional school. You can check a school’s accreditation status by contacting the school directly or by visiting the accrediting agency’s website. Learn more about 21K School accreditation here.
