Asian (last reported 2024), Black (last reported 2023) and Two or more races (last reported 2022) stop before 2025: IL suppresses a group once too few of its students are tested, so the line ends rather than the school having stopped testing.

Percent meeting or exceeding the state standard, by student race and ethnicity. Only groups IL reports for this school appear — small groups are suppressed at the source to protect student privacy, so a missing line means too few testers, not zero.
