 | The public school enrollment projections are based upon trends observed in the number of students moving from grade to grade.  The Grade Progression Rate Method was used  to project enrollments for 2nd through 12th grade.  This is a ratio of the enrollment in each grade-level and year who then enroll in the successive grade-level and year.  This ratio is then multiplied by the number of enrollees in previous grade level and year.  The kindergarten and first grade enrollees are projected using historical ratios of past estimates of numbers of births in each school district in relation to past enrollments of kindergarten students 5 years later (and first grade students 6 years later).
