The total number of students enrolled at The Sanibel School (K-8) during the reporting period. This number is divided into the number of students enrolled at The Sanibel School whose primary residence is located outside of Sanibel Island (off-island) and those that are listed as living on Sanibel Island (on-island). Enrollment levels reflect the size of the school-age population connected to the Sanibel community. Changes in enrollment may reflect shifts in resident population, housing patterns, or family residency trends. The reason to show the split is that number of students commuting shows the regional role of the school within the broader community and for those staying on island, shows the long-term residential stability within the community.
