The school maintains a 17.4:1 student-teacher ratio and per-student spending of $8,254. The identical 82.5% graduation rate reported for school, district, and state is notable, possibly reflecting data aggregation, but it also aligns with the area's overall healthy academic picture. The principal takeaway for parents is that this is a school with strong upward momentum, exceptional science and ELA instruction, very low chronic absenteeism, and a tightly knit learning environment—with math performance as the one area worth watching in future years.
