In addition, September 3 is the last day for IAR corrections for the purposes of accountability and the School Report Card for school year 2021. You may continue adding your RNVTA codes up until this date.

Learning Renewal Interim Assessments

If you are interested in participating in the Learning Renewal Interim Assessments, please respond to LRIAssessment@isbe.net by August 31. We encourage you to take full advantage of this opportunity.

Benefits to using the Learning Renewal Interim Assessments:

  • Provide timely or immediate individualized diagnostic information to the teacher.
  • Will only take about 45 minutes to administer each content area.
  • Offer useful data to teachers so they can adjust their instruction and allow for more individualized support.
  • Can be customized to match the scope and sequence of the district's curriculum.
  • Will be administered three times per year so that you can actually see student growth.
  • Allow for student mastery because it is computer adaptive.
  • Are a “best practice" toward learning recovery.
  • Are free to school districts, which allows for equity and access for districts that cannot afford interim assessments locally.

Important 2021 IAR Administration Update!

All Students Taking an Online Test Form Will Take Three (3) Test Units for the ELA Assessment.

All students who are scheduled to be administered the online IAR assessment will be given a shortened 3rd session. Schools should prepare to allow between 10-20 minutes for students to complete. No headphones will be needed for this portion of the test. This session will be composed entirely of multiple-choice items and will not be used in the calculation of a student score. Test Administrators should use the same test administration scripts they use for other ELA/L sessions.​​
