    I believe costley lack discipline also. The student have no real consequences for their actions. If suspended and attend school they are sometime let in even though they have been suspended. No real punishment. As well as no real insentive that will motivate them to do better. I would not recommend this school. Although the teacher do the best they can but without administrative support your child will only go but so far. I moved my child to another school.

    This school is definitely lacking in consequences for bad academic as well as behavior. Teachers have very little control over their classes. The children are undisciplined and rowdy. Academic deadlines are not met. If at all possible do not enroll your child at this school. Before entering 6th grade if you have to remain in the area move your child to one of the schools of the arts before they have to audition to gain entrance otherwise unless you plan to admit your child(ren) into private school the choices are limited.
