Sounds like a close connection between home and school - that's great.

How do they determine academic eligibility though?
Forgive me, but I am a bit fuzzy in trying to interpret what you mean.
So let me answer this way and see if it answers your question:
SHORT answer: They are eligible based on their current level as if they were in public school as determined by age. For simple academics, if they do not have the knowledge, it would be obvious I am sure. A student who is not academically qualified will not do well in the course work and possibly would flunk as would happen in the real world.
LONG answer:
Children in Florida, can be no YOUNGER than the compulsory age for a given grade.
Compulsory attendance begins at age 6 and the child can start (if they are academically eligible) first grade. Often though, it is difficult to prove they are ready for first grade. So it is advised that parents choose to homeschool (or not

) Kindergarten, then they should also homeschool first grade as well. B/c after that first year of compulsory education, then they will just place you in the proper academic year to your age.
So age 7 prior to 9/1 is 2nd grade, age 8 is 3rd grade, age 9 is 4th grade, et cetera...
I am fuzzy on the states rights regarding this, but essentially if your child is not performing on grade level (in regards to "standard" basics such as reading, writing, and math) there can be some wiggle room on this. So in that case if a parent is planning on later to send their child to public school, it is in their better interest to "keep" their child at least on grade level. But I haven't heard of anyone having too much difficulty placing their child in the classroom when they feel the time is right or necessary to do so (I have known several who have done this), so I think barring your child having developmental issues academically, physically, or psychologically, they just mainstream in. If they are dumb as a rock academically when there is no reason for their academics to have suffered (due to disability or any ongoing external factors)--it will be caught and the state can knock them down a level if necessary.
The same would hold true for any course work taken al a carte.
For any services, they would consult with the county to determine eligibility. Once eligible, then the student can take advantage of those services.
For activities, auditions or tryouts would be necessary.
If that didn't answer your question, I can try again.
