Reading level relates to an individual student's reading comprehension ability. Reading level indicates the most difficult text a student can comprehend based on a standardized test (such as Star Reading) or results from Reading Practice Quizzes. For example, the Grade Equivalent (GE) score in Star Reading measures the highest level at which a student can comprehend short passages on a test. This is not the same level that a student should be expected to read consistently and for long periods (such as up to 60 minutes of daily reading practice). GE scores can be a useful way to estimate a range of book levels that are appropriate for a student.
