Summary:

Plainfield Public School District includes 15 schools: 10 elementary schools, two middle schools and three high schools. Elementary proficiency averages across grades 3–5 were 25% in ELA and 24% in math, compared with state averages of 49% and 47%, respectively—a gap of about 24 percentage points in both subjects. The most important finding is that these low overall averages hide substantial differences among schools, including a clear elementary standout.

Frederic W. Cook Elementary led the district’s elementary schools in ELA and math in every tested grade in 2025–26. Its grade 5 ELA proficiency was 63%, versus 11% at Evergreen Elementary; grade 4 ELA was 53% at Cook and 6% at Stillman Elementary. In middle grades, Plainfield Academy for the Arts & Advanced Studies led listed schools in grade 6 and 7 ELA and math, and graduated 100% of students in 2024–25. Hubbard Middle had a standout 97% in grade 8 Algebra I, 23 points above the state result. High-school indicators are less reassuring at some schools: Plainfield High School graduated 70%, compared with 89% statewide, while Pinnacle Academy High School had 75% chronic absenteeism.

Elementary results moved farther from state averages between 2024–25 and 2025–26: ELA averages fell from 27% to 25%, and the gap from the state widened from 23 to 24 points. Math averages were about 24% in both years, while the gap widened from 23 to 24 points. Individual schools can differ from that trend; for example, Cook remained the elementary leader in the latest year. SchoolDigger ranked Cook 592nd of 1,331 schools, with 3 stars, while Plainfield High ranked 413th of 434, with 0 stars. As context, in 2024–25 Cook had a 5.5 student-teacher ratio and 50% free/reduced lunch eligible; Pinnacle had a 22.3 ratio and 75% free/reduced lunch eligible. Some Pinnacle test results are suppressed, so its available scores do not give a complete academic picture.
