Star Unified Scale Score and Spanish IRL
The Star Unified Scale score is the actual score that a student received on the Star Reading Spanish assessment. It is calculated based upon the difficulty of the questions and the number of correct responses. It ranges from 600–1400. The score can be seen on both the Monitor Student Mastery view and the Review Student Results view.
The range of the Star Unified Scale score for all Star programs is 0–1400; however, scores for Star Reading Spanish do not span the entire range. See the Reading Dashboard help for more information on the Star Unified Scale.
Spanish IRLs can be found on the following reports:
