Credit Flexibility 
Credit flexibility is a State of Ohio Department of Education program designed to increase curricular options available to students, increase the depth of study available for a particular subject and tailor the learning time or conditions needed to complete a high school diploma and/or postsecondary degree.

The program documents from the State of Ohio Department of Education can be helpful for states or countries that are searching for ways to provide students or citizens with credits for skills developed outside the traditional education system. Web Link
