This is ridiculous!
I graduated from a public High School at age 17.
(simply by virtue of a late b’day, not superior intellect)
If the requirement is “graduation” what does “age” have to do with anything?
Now, if you suggest the states may further encumber “graduation” requirements, that is a different story and should be slammed at the state and local level.
That there is an age restriction on taking the GED meant that our children never qualified for state university or community college scholarships. I do know that it could impact those homeschoolers wanting to join the military.
My three homeschoolers are now past their mid-twenties. Two have masters degrees. Of these, one has a masters in accounting and the other a masters in mathematics. The youngest earned a B.S. in mathematics and is currently working full-time and working on a second undergraduate degree.
