What questions can the Education Impact Calculator answer?

       1. Comparing achievement scores of students in one group to students in another similar group. For instance, school board members or parents might want to know more about the differences in achievement scores of schools in their district. Are these differences large enough to be considered educationally important or statistically significant? Policy makers might want to know more about differences between districts. Are the differences between two districts large enough to be considered educationally important or statistically significant? 

 )      2. Comparing achievement scores of students in one group to those in a larger population, such as the district or state. State assessment scores are routinely published for individual schools, districts, and the state as a whole. With the EIC consumers can find out if the differences between their school and the district or state are large enough to be educationally and statistically significant.  

3)      3. Comparing achievement scores for students in one year to those in another year. When schools or districts introduce new curricula or other innovations it is important to assess the impact of the change. The EIC allows consumers to compare the results before the change was introduced to the results in subsequent years. For example, one might compare the percentage of fourth graders at benchmark in 2013 with the percentage of fourth graders at benchmark in 2015.

4)      4. Comparing changes over time in one group to changes over time in a similar group. This option expands the comparison over time that is in option three. It allows consumers to compare changes from one year to the next in their school or district to changes over this time period in another school or district. 

5)      5. Comparing changes over time in one school to changes in a larger population, such as a district or state. This option gives additional controls to the comparison in number three by looking at how the change in a school from one year to the next compares to the changes in the district or state. For example, one can assess the educational and statistical significance of the change in percentage of fourth graders at benchmark in one school relative to the changes seen in all schools in the district or state.
