UPDATE: West Ada enrollment jumps 1,200

West Ada School District reported a preliminary enrollment increase of 1,243 student on its opening day Monday, one of the largest since the start of the recession.

At the same time, Boise School District reported a decline of 150 students led by a drop in kindergarten enrollment.

West Ada School District showed 37,766 students enrolled in school this year, compared with 36,523 last year.

District officials expect the numbers will drop by about 250 over the next several days, leaving a net increase of about 1,000.

West Ada hasn’t seen that level of year-over-year increase since 2008-2009, said Eric Exline, district spokesman.

In Boise, Monday’s preliminary enrollment, which is expected to change, was about 25,324, down from 25,474 on opening day in 2014.

Don Coberly, district superintendent, said the kindergarten class alone dropped from 1,756 to 1,704. The district also saw a decline in first grade from last year.

Coberly said declining birth rates during the recession are a likely reason for dropping enrollment.
