Summary:
Thompsonville CUSD 174 has one elementary school, Thompsonville Grade School, serving prekindergarten through eighth grade and enrolling 204 students. Its latest reported results show a mix of strengths: all-grades English language arts (ELA) and fifth-grade science were above Illinois results, while all-grades math was below. The clearest overall takeaway is that ELA is a relative strength, but math remains the school’s main achievement gap with the state.

The strongest reported grade-level result was seventh-grade ELA, at 76% compared with 58% statewide. Fifth-grade science was another standout: 65% proficient, 17 points above the state. ELA was above the state in every grade with a reported school result, though the size of the advantage varied.

ELA rose 15 points, from 49% to 65%, while the state rose 3 points; math increased 12 points, from 16% to 27%, but remained below the state. Fifth-grade science jumped 58 points, from 7% in 2024–2025 to 65% in 2025–2026, moving from 34 points below the state to 17 points above.
