When data are inconsistent during annual reviews, what sequence best ensures an up-to-date and accurate IEP?

• A. Review data histories, gather new data, consult with the team, verify accuracy, and update the IEP accordingly.
• B. Ignore the inconsistencies and proceed with the existing plan.
• C. Cross-check data with at least two sources, collect any missing data, involve the family, and revise the IEP as needed.
• D. Delay updates until the next annual review.

Answer: (C)

When data are inconsistent, you want to build a solid, up-to-date picture of the student's needs by verifying information through multiple sources, filling any data gaps, and involving the family before updating the IEP. Checking data against at least two independent sources helps confirm what’s really happening rather than relying on a single point that might be biased or incomplete. Collecting missing data ensures you don’t miss important aspects of the student’s progress or barriers. Involving the family brings essential insights, routines, and context from home that can influence performance and participation. With this corroborated, comprehensive information, you can revise the IEP to reflect accurate goals, services, and accommodations. Delaying updates or proceeding with an inconsistent or incomplete picture risks ineffective supports and misalignment with the student’s current needs.
