Indiana Learning Evaluation Assessment Readiness Network (ILEARN) is the summative accountability assessment for Indiana high school students in Biology. Students are required to participate in the ILEARN Biology End-of-Course Assessment (ECA) upon completion of the high school biology course to fulfill a federal participation requirement. A student may only have one test attempt for any given ILEARN assessment. There are no retest opportunities available for ILEARN assessments. ILEARN is an untimed assessment.
