The discipline gap: who gets suspended at Washington public schools

Washington's statewide discipline rate in 2023-24 was 4.5% — about 1 in 22 students. For Black students it was 11.3%, for Native Hawaiian/Pacific Islander students 13.9%, for American Indian/Alaska Native students 11.6%. At the 217 Washington schools that publish non-suppressed rates for both Black and White students, the median Black rate runs 5.9 points higher than the White rate at the same building. 92% of those schools show Black students disciplined more often than White students.

11.3% / 4.2%
Share of Black students vs. White students disciplined statewide in Washington public schools in 2023-24 — a ratio of about 2.7 to 1

OSPI publishes a discipline rate for every public school: the share of enrolled students who received at least one short-term suspension, long-term suspension, expulsion, or emergency expulsion during the year. The statewide enrollment-weighted rate in 2023-24 was 4.5% — about one student in 22 — but that number averages over a wide variance both between schools and between student groups.

The statewide picture by race

2023-24 discipline rate by race in Washington public schools (state aggregate, denominator-weighted across all schools that report)
Native Hawaiian / Pacific Islander13.9%
American Indian / Alaska Native11.6%
Black11.3%
Two or More Races8.5%
Hispanic / Latino6.3%
All students4.5%
White4.2%
Asian2.8%

Computed directly from OSPI's school-level discipline file (data.wa.gov dataset sm68-769y), rolled up across all schools' published Black/White/etc. denominators and numerators. Suppressed cells (denominator <10) are excluded.

On the same OSPI source we use for school-level rates, Black students are disciplined at 2.7 times the rate of White students; Native Hawaiian/Pacific Islander students at 3.3 times; AI/AN at 2.7 times; Hispanic at about 1.5 times. Asian students are disciplined at about two-thirds the White rate.

But the within-school gap is what reporters want

The state-aggregate gap can be largely explained by which schools each group disproportionately attends — Black and Hispanic students are concentrated in higher-poverty schools, which have higher overall discipline rates regardless of race. The sharper question is whether students at the same school get disciplined at different rates by race. OSPI's school-level discipline file publishes per-race rates per building, with cells suppressed where a subgroup is fewer than 10 students. We pulled all schools where both the Black and the White discipline rate are non-suppressed and the denominator for each is at least 20 — a sample of 217 schools statewide.

Median Black-minus-White discipline-rate gap at the same school (n=217), and the share of those schools where Black students are disciplined more often than White students

Eight percent of the 217 schools have Black students disciplined at a lower rate than White students — a real but small minority. At the other end, more than a quarter of the 217 schools show a Black-White gap of 10 percentage points or more, and a substantial chunk of those are middle schools.

Computed from OSPI's school-level discipline file (sm68-769y). *Green Hill is a juvenile rehabilitation facility school, where the population is itself selected for prior discipline history; we include it for transparency but the comparison isn't a fair read on a typical school. Three of the top ten are Tacoma SD middle schools, which is a real pattern worth investigating.

Tacoma School District has four middle schools in the top ten by within-school Black-White gap (Oakland HS, Hilltop Heritage, Truman, Gray). That's not statewide cherry-picking — those four schools together produced about 18% of the schools-in-the-top-25, despite Tacoma SD being about 2% of Washington schools by count. Federal Way SD, Clover Park SD, and Spokane SD each show up too. The geography is south Sound + a single Spokane site; the level is overwhelmingly middle school.

And the poverty gradient

WA K12 Academic Atlas; quartiles defined on each school's low-income share of enrollment.

Schools in the highest-poverty quartile have median discipline rates roughly double those in the lowest-poverty quartile (4.0% vs 1.9%; Pearson r = +0.27 between low-income share and discipline rate). 129 Washington public schools discipline more than one in ten of their students; 11 schools discipline more than one in five. Many of the highest-rate schools are alternative or option placements where students were sent because of behavior history, so the rate isn't directly comparable to a comprehensive school's; we flag this rather than mix them.

What we still can't see well: discipline rates by race × school × grade with non-suppressed cells. OSPI's file publishes by grade, but the per-grade × race × school cells get suppressed far more aggressively than the all-grades × race × school cells we used above. The reporter-ready view here is the 217-school cross-section of all-grades within-school gaps; the next level of detail would need a public-records request or OSPI changing its suppression threshold.

Methodology

Source is OSPI's 2023-24 school-level discipline file on data.wa.gov (Socrata dataset sm68-769y), pulled into data/parquet/discipline_2023_24.parquet as part of the WA K12 Academic Atlas build. The file publishes for each (school, student_group, gradelevel) tuple: discipline denominator (enrolled count), numerator (disciplined count), and rate. We use the rows where organizationlevel='School' and gradelevel='All' (the all-grades roll-up). State-aggregate by-race rates are denominator-weighted across all schools' published Black/White/etc. rows, with suppressed cells dropped. For the within-school Black-White gap, we keep schools where both the Black row and the White row have non-null denominator and rate AND each subgroup denominator is ≥20 (a sample of 217 schools); we then compute Black-rate minus White-rate. The chart of largest gaps further requires that both numerators be reported (not suppressed). The poverty-quartile chart at the bottom uses the broader universe of public schools with enrollment ≥50 and a non-null overall discipline rate (n=1,428), with quartiles defined on each school's low-income share. Note: an earlier draft of this piece cited "7.1% Black / 3.1% White ≈ 2.3x" from a single news-article reference. The figure on this page (11.3% / 4.2% ≈ 2.7x) comes directly from OSPI's published school-level file rolled up to the state and is the rate to use.
