Schools can use a variety of techniques, based on their individual needs, to integrate multi-level intervention classes into their schedules. Such integration generally depends on the existing school structure. Often, using elective periods is the most common approach to scheduling secondary- and tertiary-level classes. For example, if a school used a 7-period school day, and two of those periods were for elective classes, then the school designated the electives as intervention classes for students needing interventions. Additional options are to shorten the time of their classes (e.g., by 5 minutes) and add an additional class period to the school day. Also you may look at shortening transition times between classes to increase instructional time.
