According to the Policy Handbook for Elementary and Secondary Schools in the Archdiocese of New Orleans:
All tuition payments must be up-to-date one month before the end of each semester.
If tuition is delinquent one month before the end of the Fall semester, the student may not be permitted to return to school after Christmas break.
If tuition is delinquent one month before the end of the Spring semester, the student may not be allowed to return to the school for the next school year, even if the student is already registered.
Schools are not obligated to allow students with delinquent tuition to return for the next school year.
