As of Friday, the district reported the preliminary for the new year was 17,968 - with more students still checking in (Right now we are at 17,968 total but our halls are packed with students coming in.”).

A new enrollment projection report given to the School Board earlier this year predicted steady growth for the district in coming years. The report projected enrollment will grow by nearly 850 students during the next five years.
