From the time of its inception in the 1850s until the early part of the 20th century, the Adventist Sabbath School in North America was highly attended. During those times Sabbath School reached the highest attendance rate when Sabbath School membership was sometimes even larger than church membership. Following that time, the attendance rate at Sabbath School has significantly declined. Currently it is estimated that less than 25% of the Seventh-day Adventist Church membership in North America attends Sabbath School on a regular basis. This study explores factors related to declining attendance at the adult Sabbath School in the North American Division of the Seventh-day Adventist Church.
