Revise education laws related to PIR days and meetings of teacher organizations

Added 'end-of-term records days' to the list of activities that count as pupil-instruction-related days.

Updated the definition of professional development to require that it be aligned with the standards of the Board of Public Education.

Rephrased the exclusion of state teacher organization meetings to clarify that these activities are not included in the count of pupil-instruction-related days.

Added a requirement that professional development must be solely devoted to improving instruction and aligned with state standards, while explicitly prohibiting political activity and divisive partisan content.

Changed the requirement for school trustees to close schools for teacher organization meetings from a mandatory mandate to a discretionary permission, allowing boards to choose whether to close schools.

Updated the definition of allowable activities to ensure state meetings of teacher organizations are only permitted if they meet the new educational alignment standards.

The bill title was changed from LC 0384 to HB 557.1, and the list of primary sponsors was updated to include the current legislators.
