This page includes data from the Wisconsin Department of Public Instruction on Grade 3 Reading proficiency. The Grade 3 Reading proficiency rate is the percentage of all Grade 3 public school students rated as proficient or advanced in grade-level reading based on the annual Wisconsin Knowledge and Concepts Examination. The Grade 3 Reading performance gap is the percentage point difference between the Grade 3 Reading proficiency rates of the economically disadvantaged and non-economically disadvantaged Grade 3 public school students. Economic disadvantage is based on income eligibility for free or reduced-price lunch. Economically disadvantaged students tend to perform at much lower proficiency rates than non-economically disadvantaged students.
