“There are five characteristics that can define an intervention as more intensive: Frequency. The more often a child receives a particular support, the more intensive the intervention. Duration. The more time a student spends receiving a particular support, the more intensive the intervention. Ratio. The smaller the teacher-to-student ratio, the more intensive the intervention. Targeting. The more aligned a particular support is with the individual needs of a specific student, the more intensive the intervention. Training. The more highly trained the staff member is in the student’s area of need, the more intensive the intervention.”
