An intervention is a system of scaffolded, research-based, instructional supports to progress a student on a targeted strategy/skill to mastery. Research has shown that for interventions to be successful there are four key components:

    1. Proactive - Accurate and ongoing evaluation of data to address areas of need before they are a problem
    2. Intentional - Strategies are consistent in addressing an identified area of weakness
    3. Formal - Progress monitoring is consistent; the method to address area of weakness is targeted and specific
    4. Flexible - Scaffolding takes place to meet the need of the individual student

    An intervention is specific academic skill instruction that differs from activities occurring in the student’s classroom as part of the general curriculum.  An intervention is designed to build/improve an at-risk student’s skills in areas that are necessary to allow him/her to achieve grade-level expectations.

    An intervention is:

    • Focused on remediating a skill deficit(s).
    • Provided in a small group or individually.
    • Provided in addition to not in place of the core curriculum.
    • Provided consistently a minimum of three times a week over a period of at least 6 weeks.



    Differentiation includes changes to instruction designed to meet the needs of all students at different instructional levels within the classroom and should be a natural part of good core instruction at Tier 1.  It may also include additional small group instruction and/or purposeful design of instructional materials within the classroom.


    Modifications may be changes in instructional level, content, and performance criteria, and may include changes in test form or format or alternative assignments.  It is reducing demands not lowering expectations.


    Accommodations are changes in how students access their learning or how they are tested. Accommodations eliminate obstacles that may interfere with a student’s ability to perform or produce at the same standard of performance as all general education students.
