To summarize it up, every school has changed location and/or grade levels served at least once (Jefferson is the only one of the schools that hasn't changed location). In the mid-to-late 1990s, Jefferson only had 1st and 2nd grades and Madison only had 3rd and 4th grades. Washington had at least a couple first grade classrooms when I attended kindergarten there in 1997-98.
As for the high school, it has changed quite a bit since I graduated and that was just last year. For this past school year, the school switched back to semesters (after five years of trimesters, meaning that I was one of two classes to have trimesters... for all four years of high school), moved the assistant principal to a grade school as a principal, moved the middle school assistant principal to the high school, and went "paperless". For this upcoming school year, they are moving seventh and eighth graders up to the high school as a result of closing two of three elementary schools (I am not sure if the HS building can hold ~750 students) and converting the current middle school, which was the high school until 2003, into an upper elementary school, leaving the remaining elementary school (Jefferson) as the lower elementary school.
