According to Wikipedia "Seventh-day Adventist education is the second-largest Christian educational system in the world. It is also considered the largest Protestant educational system. The church operates 9,845 educational institutions across over 100 countries, with 2,177,933 students in 2023. This includes 6,897 primary schools and 116 tertiary institutions."

The Meaning and Importance of “True Education”

"Let’s start by examining the foundational concepts and emphases of the mission of Seventh-day Adventist schools. 

As the Adventist denomination was forming and growing fast, early Adventists recognized a need in their communities for “true education“—a system of learning and development that included and emphasized family values and Christian principles. This was a welcome idea compared with the public education system at the time, which didn’t place much importance on morality or values and ignored many health and physical fitness principles as well.

So true education became a whole-person focus: striving to enrich the students’ minds and bodies, which also included spirituality and socio-emotional growth. 

These values included educational standards that existed in all Adventist schools at a time before public education in the United States was standardized across all schools. This meant that, depending on location, a child’s educational experience could vary significantly. So it was noteworthy that Adventist students learned the same principles and educational building blocks no matter where they might attend an Adventist school. 

This type of education included not only the children, but the whole family as learners. And it added a very important textbook—the Bible."
