In this series: Hawaii 2025-26 Enrollment.

Hawaii's published grade 9 total was 13,958 students in 2025-26, the largest of the state's thirteen totals from kindergarten through twelfth grade. It stood 640 students above grade 4, the next-largest grade at 13,318.

Kindergarten, by contrast, enrolled 11,637 students. Grade 9 was 2,321 students larger, or 119.9% of the kindergarten total.

Those same-year totals show the shape of enrollment, not the movement of individual students. The package does not link a child in one grade and year to that child's enrollment status a year later.

The latest cross-year comparison

The published statewide grade 8 total was 12,675 in 2024-25. The grade 9 total one reporting year later was 13,958. That is a net difference of 1,283 students and a grade ratio of 110.1%.

The calculation is simple: next-year grade 9 minus prior-year grade 8. Its interpretation is narrower. It does not prove that 1,283 students transferred into public schools, and it does not identify private school, charter school, homeschool, migration, retention or data classification as the source of the difference.

Fourteen comparable transitions

The 2011-2026 panel provides 15 adjacent-year grade 8-to-grade 9 comparisons. One is not comparable: the package reports 18,036 students in a separate statewide SPED grade row in 2023, but no separate SPED row in 2024. The complete kindergarten-through-twelfth-grade rows therefore cross a reporting boundary between those years, so the 2023-to-2024 comparison is excluded from historical summaries.

All 14 remaining comparisons have a positive net grade-count difference. Among the 12 comparable transitions beginning from 2011 through 2022, the mean ratio was 111.7% and the mean net difference was 1,354 students. The low was 107.3% for the 2020-to-2021 comparison; the high was 117.3% for 2011 to 2012.

The two comparable transitions after the reporting change are close to that earlier range. Grade 8 in 2024 to grade 9 in 2025 produced a 1,342-student difference and a 110.4% ratio. The latest comparison produced 1,283 and 110.1%. Their mean ratio was 110.3%.

County systems and the charter aggregate

The latest comparison is positive in each of the four published county-system rows and negative in the separate statewide charter aggregate.

Reporting entity	Grade 8, 2025	Grade 9, 2026	Net difference	Grade ratio
Hawaii County	1,697	2,084	+387	122.8%
Maui	1,445	1,687	+242	116.7%
Kauai	660	753	+93	114.1%
Honolulu	7,617	8,495	+878	111.5%
Statewide charter aggregate	1,256	939	-317	74.8%

The five grade 8 rows sum to the published statewide grade 8 total of 12,675. The five grade 9 rows sum to the published statewide grade 9 total of 13,958. That reconciliation confirms the reporting boundary: charter enrollment is a separate statewide aggregate, not allocated among the four county rows.

The table does not show where individual students went. A negative charter difference and positive county-system differences are consistent with several possible flows, but aggregate rows cannot establish a transfer between them.

Grade 9 and kindergarten have reversed positions

In 2011, kindergarten enrolled 15,010 students and grade 9 enrolled 13,312. Grade 9 was 1,698 students smaller, or 88.7% of kindergarten.

By 2026, kindergarten was 11,637 and grade 9 was 13,958. Grade 9 was 2,321 students larger and 119.9% of kindergarten, a 31.3-percentage-point swing from 2011.

That reversal compares different grade groups within the same reporting year. It does not follow one birth cohort through the system, and it cannot by itself distinguish births, migration, sector choice, grade repetition or other mechanisms.

The next grade comparison also needs caution

The published grade 9 total was 14,241 in 2024-25. Grade ten enrolled 12,980 one year later, a net difference of -1,261 and a ratio of 91.1%.

Calling that difference a dropout or retention count would make the same mistake in the other direction. Without linked student records, the aggregate comparison cannot show whether the students represented in the two totals are the same people.

What the data can support

The durable finding is structural: in every comparable year pair in this panel, next-year grade 9 was larger than prior-year grade 8. The latest grade 9 total was also the largest published grade from kindergarten through twelfth grade and substantially larger than kindergarten.

Explaining why requires evidence the enrollment file does not contain: linked student records, prior school sector, entry and exit codes, grade repetition, and geographic moves. Until those are available, the grade totals can measure the pattern but not assign a cause.
