The Hood River County School District has seen unexpected enrollment growth this year, with the most recent count showing the district up by 56 students…the biggest jump in about a decade.  But the difficult part for district administrators is trying to determine is if this simply a bubble or part of a long-term trend.  Superintendent Dan Goldman says there are signs that would make the district expect more growth, particularly in the lower portion of the Hood River Valley.  Goldman used May Street Elementary School as an example, noting there is no more space to add a classroom there.  He says additional classroom space will be a big discussion point for the district as they prepare to go out for a bond measure in the near future.
