Ed Trust on the Achievement Gap

Ed Trust is out with a study looking at how states have done since 2003 on the achievement gap: Gap.pdf.  It looks at a number of different ways one can measure progress (or lack thereof):


To gain a true picture of gaps in student achievement requires looking at the data from at least four different perspectives:

• Simple Gap Narrowing: Have absolute gaps in mean performance between groups decreased over time?

• Progress for All: Have all groups of students gained over time?

• Gap Size: What is the current size of the gap between groups?

• Group Comparisons Across Jurisdictions: How does each group of students currently perform compared with their counterparts in other jurisdictions?
