So today (9-27-18) my kids come home from school...they qualify for free lunches but the applications had expired. My kids tell me that they are taking an abundance of the kids school lunches since their app had expired... My problem is as a parent that I was in no way informed that this had happened and my kids had food pretty much pulled from their mouth. And since there appears to be a lot of people that this is happening to in one day then I believe the school sent out no notice at all! There is no way that many parents didn't just do the application. This is wrong and someone should be apologizing for singling out the kids and embarrassing them they way they have for their negligence.

This school needs to have more activities because my daughter and a bunch of her friend just love Japanese anime . But they have no where to learn the culture or the history of it and this is the lone thing i dislike about this school . But in the end i believe this school is great .

This school is amazing. The teachers are great, and the administration is outstanding. Sebastian offers a wide variety of school Clubs, as well as sports. My son didn't like his old school back in New York, but when we moved here to Sebastian, it's like he lives only for school. If your looking to move down to Sebastian,
I TRULY recommend this school!
