The district administration needs to do more research before it presents the School Committee the specific number of students who have left Swampscott for private schools.
School Committee member Jaren Landen had requested the information last month.
The departing student information compiled by the superintendent's office as of the last School Committee meeting, last week, was incomplete, according to Committee Chairman Larry Beaupre.
The district did not have the number of students lost to at least some parochial schools including St. John's Prep.
The chairman expects the information will be available at a future meeting.
The district has been asking parents of the departing students the reason or reasons why they opted to send their children elsewhere, the chairman said earlier.
Maintaining strong enrollment numbers in the district is important, in part, because it determines the amount of education funding the district receives from the state.
