Format
All 4 of the Sergeant Bluff-Luton schools follow a Semester format and the High School uses block scheduling with four 90 minute classes a day.
Students have alternating "A" and "B" days and therefore only have each of their classes two or three times a week.
The district converted to semesters from trimesters for the 2010-11 year.
