New research continues to show the validity of the Independent Reading Level Assessment (IRLA). The evidence-backed IRLA, in addition to delivering specific and actionable information that drives instruction, also serves as an indicator of how students will perform on end-of-year standardized tests.  Updated from the fall release, Edition 2 of the Validity of the IRLA Research Brief includes: 

• Results from 13 studies conducted in districts across the country

• IRLA and state test score correlations in DE, OR, WA, and WY

• IRLA and interim assessment correlations in MN, NE, NY, OR, RI, and WA
