Which element best supports measurement of success within an IEP?

• A. Documentation of personal preferences alone.
• B. Timelines provided with no criteria for success.
• C. Criteria for success, timelines, and progress indicators.
• D. A list of unrelated personal achievements.

Answer: (C)

Measuring success in an IEP relies on having clear, observable goals and a plan to track progress. The best choice includes criteria for what counts as progress, a timeline for when goals should be reached, and progress indicators or data-collection methods to monitor advancement. This combination lets educators determine when goals are met and when instructional adjustments are needed.

Documentation of personal preferences alone doesn't specify learning outcomes. Timelines without criteria for success offer no standard to judge progress. A list of unrelated personal achievements isn't tied to the student's IEP goals and therefore doesn't demonstrate progress toward those objectives.
