Summary

William Mason School is an elementary school located in Montville Township School District, serving 290 students from kindergarten to 5th grade. The school consistently outperforms the state average on standardized tests, with 63.7% of 3rd graders proficient or better in ELA compared to the state average of 44.9%. William Mason School also maintains low chronic absenteeism rates and serves a relatively affluent student population, with only 2.35% to 5.17% of students receiving free or reduced-price lunch.

While William Mason School is a high-performing institution, it is not quite at the same level as some of the top-ranked elementary schools in the Montville Township School District, such as Hilldale School and Valley View School, which have even higher test scores and lower chronic absenteeism rates. However, William Mason School still maintains a strong reputation and provides a quality education for its students, with a low student-teacher ratio and consistent performance across different student subgroups.

Interestingly, William Mason School's spending per student of $19,549 in 2018-2019 is higher than the state average and the nearby schools in the Montville Township School District, which range from $13,513 to $19,750 per student. This investment in the school's resources may contribute to its overall academic success and positive learning environment.
