The economy may not be growing right now but enrollment in the Twin Falls School District sure is.  Enrollment is up 102 students in the district compared to the same time last year with a total of 7,801 students.  As a result the Twin Falls School Board voted this week to make a couple of staffing adjustments.  An additional kindergarten teacher will be hired for Morningside School and a third grade teacher at Lincoln Elementary School will be transferred to teach 5th grade at Oregon Trail Elementary.  Oregon Trail, in the South Park area, experienced the largest increase in enrollment of the schools in Twin Falls with an additional 30 students this year over last year.  School Superintendent Wiley Dobbs says small adjustments at the beginning of each school year are normal and enrollment wise, the district is just about where projections indicated.
