In order to apply for membership in Job's Daughters, one must be a girl between the ages of 10 and 20. The original age for membership was 13–18, as stated in "The Official History of the International Order of Job's Daughters", but has been changed several times over the years. Until August 2015, the girl must be related to a Master Mason or Majority Member. Now, she may be sponsored by a Majority Member and Master Mason if no relation is found.
