I followed your link below and these 1,000 students are part of the 3,000 students total in Lahaina.

There are still 2,000 missing enrollments [since the fire].

from the article:

As of Monday only 538 of the Lahaina students had reenrolled in other Hawaii public schools, and 438 students had signed up for the State Distance Learning Program, according to a “Maui Wildfire Impacts” report that state Schools Superintendent Keith Hayashi is scheduled to present today at a state Board of Education meeting.

That leaves 2,025 Lahaina students “who have not enrolled in another public school or opted for distance learning (may have moved out of state, enrolled in private schools),” Hayashi’s report says.

I did a search with those words and came up empty.
