School bells are ringing again across the State of Wisconsin. State law requires at least 180 days of instruction. Wisconsin Administrative Code PI 8.01(f) allows for only five of those days to be used for non-instruction, such as parent-teacher conferences or snow days. In addition, unless given DPI approval, public school districts may not commence the school year before September 1, see Wisconsin Statute 118.045 and Administrative Code PI 27.03. Although school cannot start before September 1, the law does not prohibit any school district from holding year-round school.
