Enrollment in the White Salmon Valley School District is essentially flat from last year, but up by 20 students from what was projected heading into this school year.  Superintendent Rich Polkinghorn says they projected 1,042 students, but as of Friday were at 1,062.  Polkinghorn says the jump is concentrated on the freshman class at Columbia High School, which had 15 more students than expected.  Polkinghorn adds they don’t have a specific reason why they saw the new 9th graders.  He does say at school the size of Columbia, adding 15 new students in one grade does bring challenges for staff to keep class sizes where they want to.
