Yes, Walton County is going through a similar transition. SWHS is relatively new, so it's kind of going through a "growing up" transition too. Its first year it had many students that other schools didn't want, so that was a tough year or two. Since then we've had a new principal that put a stop to that. So now most of the kids that go there are from South Walton and grew up together. For the most part it's a good group of kids and they have relatively few behavior issues. As the school has evolved, they've been able to add AP classes and focus more on the education of the kids. Sports is big here too so that gets attention too.
I would have hoped that the test scores would start to improve, but so far, they haven't really. I think it's just a matter of time. Now that we're back to a traditional schedule, and more parents are pushing for better academics, I think we'll eventually start to see test score improvement.
Improving the FCAT scores needs to include and start with the elementary and middle schools too. The middle schools are really starting to take off here. Seaside has always had good scores and now Emerald Coast (also relatively new) is doing really well too. The students that are just now coming into the high school are the ones that have had an improved education at Emerald Coast and Seaside. Perhaps we'll see a rise in high school FCAT scores as these kids go to the high school.
Strictly based on the students that I know, most seem to take both tests. Unfortunately many of them wait until 12th grade to take the tests. I haven't evaluated the SAT test taker numbers lately, but perhaps they include the lower classmen in the count? Many of our students end up going to NWFSC after they graduate and it's not a requirement that they take the SAT or ACT to get in. It is a requirement that they take it if they want Bright Futures money. There's another big perk that Florida gives their kids, Bright Futures scholarships. Look that up and I think you'll be pleasantly surprised.
BTW - the dual enrollment, collegiate high school and virtual schools are all free. Students can earn a lot of free college credit before they even graduate from HS.
As parents we all have to continue to push for better classes and higher expectations. We have to impress this upon the school administration and the school board of the county. As the expectations of the schools changes I would hope that the school board composition and expectations will change too. We've got some good people on the board, but I think the county is due for some changes. We'll see improvement as things evolve.
