As of 2024, the Annual Historian report is no longer required, and the job of Historian is no longer a required member of the executive board. Your PTA may choose to continue to collect the hours for your records but it does not get submitted to the California State PTA.
It is still an excellent entry level position for someone who would like to be a member of the board or for a student board member.
Many PTAs like to have a record of how many volunteer hours were accumulated throughout the year and the grand total presented to your school board as an example of the value of volunteering.
The historian can also serve as the person who documents all the activities of your PTA. Having a photographic record that you can show off at a back-to-school event can encourage other people to volunteer and helps to show off exactly what your PTA provides for your school community.
