I give a full Language Arts credit for successful completion (averaged grade of at least 75% for each semester) of the course. Each student will receive a PDF documenting the credit and an overall assessment of writing progress.
States differ in their requirements for documentation. I am accredited by The Institute for Excellence in Writing, not by state agencies. It is the responsibility of parents to determine whether the documentation I provide is acceptable for their state.
In Georgia, where I am based, my documentation is sufficient to meet state requirements. I am not familiar with the requirements of other states. However, to date I have had students from South Carolina, Florida, New York, Connecticut, and Missouri who have returned for more classes. 🙂
