Madison Falls High School will provide you with a qualification which is recognized by the US Department of Education. The organization may provide what it says, so anything saying its a scam (i.e. It is not fraudulent), but when you read the small print you can see they do not actually provide a high school education or award any nationally recognized and accredited qualifications.
The Madison Falls High School website appears to offer a free high school diploma but the organization is not recognized by the US Department of Education so the diploma is, effectively, worthless as a an indication of academic achievement. Effectively you simply pay for a certificate which looks like a legitimate high school qualification.
The website implies the diploma is accredited but the actual small print only states that the school is a member of the American Accreditation Council of Higher Education, an organization which does not appear to exist. Readers, and search engines, may confuse this with the Council for Higher Education Accreditation, but they are definitely not the same organizations.
This website asks you to complete a few online tests of 12 to 26 questions in maths, science, language/reading and social science which are approximately at high school graduate level. Once you have completed the tests you then order your diploma for which you have to pay (at time of writing) $219 plus shipping.
There is no information given about the pass rate so you may well be able to pass the tests with a score of zero. If you can’t manage the test, there is also an opportunity to simply state which life skills you have and then to write an essay about what you can do, for which no proof or verification is required.
Madison Falls High School also appear to offer a GED but actually they only sell you a GED kit and you have to take the test at a registered test center (which you will have to arrange and pay for yourself). The kit only consists of resources you could get yourself such as popular study guides, a calculator and a stress ball.
If you are looking to get a genuine high school diploma or GED make sure you apply to a recognized and accredited educational organization. You can check for accredited institutions using the US State Department’s accreditation database on their website.
