School Reviews

North Plainfield High School is an awful school. A few great teachers and counselors and staff, but for the most part, the rest are terrible at their jobs. NPHS students' are not set up to succeed academically or mentally because of lack of rigor and incredibly low expectations, particularly if you belong to a group that is viewed as not capital, academically, by society at large. Burn the school to the ground and bus its students to Watchung Hills.

honestly it is a bad school because they don't even give that much help in office hours they only give 1:30 to 3 back in old school they would give help 3:25 to 5 o'clock and most of the teachers don't even do their jobs also and when they teach they literally teach way to fast and some people can't even understand but some teacher actually do a good job and teach in a normal paste also some teacher can a little rude but usually complaining to us about our Wi-Fi
