Flexible modular scheduling is a type of academic scheduling where a day is broken into many 10-20 minute modules or "mods". The technique resembles some common college scheduling schemes.
One such example of high school modular scheduling is utilized at the Bergen County Academies in New Jersey. At this school, the day is broken down into 27 separate 18 minute modules. Classes vary in size, from a small class of 2 mods to a larger class of 3 mods. Labs, projects, and certain electives can even run for as long as 9 mods. Student schedules often change between different weekdays (i.e. one could have Literature one day for 3 mods, then 2 mods on the next day - or not at all). This type of scheduling allows for many free periods during the day as well as the possibility for more classes. These "free mods" can go to as long as 180 minutes of continuous free time without classes. This time could be utilized for lunch, study, or socializing. Due to the latter, students are advised to spend most of their free time in study halls so that such time is not misused. An additional bonus is the ability for students to have more than 2 elective classes (according to free time), whereas in the traditional period scheduling, students are limited to 1-2 electives.
East High School in Salt Lake City, Utah used a modular flexible scheduling system during the 1970s and 1980s until the Salt Lake School Board voted to change back to a more traditional program. At the time, it was felt that the programming difficulties resulted in too much time and effort to be feasible.
St. Teresa's Academy in Kansas City, Missouri has used a rotating modular schedule since the 1970-71 school year.
Westside High School in Omaha, Nebraska has used some form of modular schedule since the fall of 1967. Rather than study halls, Westside's modular schedule system uses IMC's (Instructional Materials Centers) as work locations for students with unscheduled, independent study time. These IMC's are curriculum-specific and are located near the desks of each subject-area's teachers.
Holland Hall High School in Tulsa Oklahoma also uses a modular schedule with 18 22 minute mods
Ursuline Academy in Blue Ash, Ohio, a suburb of Cincinnati, uses a mod schedule broken up into 18 20 minute mods.
