My daughter attended GBCS from Kindergarten through 8th grade. We could not have been happier with our experience, they provided a safe place for our daughter to figure out the way she learned best. She has graduated, but continues to view GBCS as "home" and visits frequently. As with all schools it does have challenges, however I saw the administration deal with many issues, either social or academic, efficiently and with great care.
What a warm and caring school community! GBCS seems to be a place where everyone feels truly welcome. As other reviews note this school has an amazingly dedicated staff. They struggle, however, with meeting a very diverse set of needs and often seem to teach to the lowest common denominator. Although the concept of the Personalized Education Plan (PEP) is great in theory, parents of students performing at or above grade level must be prepared to advocate for challenges in the classroom to ensure their bright kids don't get bored. The school also struggles to engage a diversity of parents in Board and other organizing efforts -- those parents that do participate are committed, but represent a very small subset of the community. Lastly, with the exception of the 2011 Talent Show (which was a truly remarkable effort), after school programming leaves a lot to be desired. The regular fee-based ASP is little more than a holding pen.
This school is very good for developing social skills. Unfortunately, there is not much help offered for children who need more challenging work. It is a struggle to get the teachers to cooperate with challenging your child's limits. They could also use more structure and discipline.
This school offers flexibility and excellent teachers. Some classes appear to be somewhat out of control but my child's teachers are better able to maintain order than others. She has done well on standardized testing but I don't about other scores. Parents are much more involved than in regular public schools. However, there still some parents who expect the school to do everything. Overall, we are very satisfied with this school.
