Focused instruction where students are academically engaged with the content and the teacher and receive more opportunities to practice with immediate teacher feedback. Intervention Instruction is provided only to students who are lagging behind their classmates in the development of critical reading skills. This instruction will usually be guided by a specific intervention program that focuses on one or more of the key areas of reading development. This type of instruction is needed by only a relatively small minority of students in a class. In some cases, students in 2nd and 3rd grade may have lagged so far behind grade level development of reading skills that very little content from the grade level comprehensive core program is suitable for them. In these cases, students may need to receive instruction guided by a comprehensive intervention program that is specifically designed to meet their specific needs while at the same time accelerating their growth toward grade level reading ability.
