All boards of education of public school districts, vocational-technical high school districts, and all boards of directors of charter schools shall digitally record all of their public meetings and shall make the recordings available to the public on the districts' or charter schools' websites within 7 business days of each meeting. These recordings shall remain available on the website for at least 1 year after their posting on the website. These recordings are not official board minutes, but are a means to enhance communication to the public and to state legislators. The requirements of this section do not apply to board executive sessions, or workshops and retreats where no voting will take place.
