COR Advantage

Modified on Wed, 19 Feb at 11:01 PM

COR Advantage is an observation-based assessment at COA for birth through PreK. It is backed by research from HighScope, which has led to its wide acceptance as the leading assessment for early childhood educators. In addition, COR Advantage software makes it simpler than ever to collect and share meaningful developmental data with all stakeholders, and keeps teachers focused on what matters most.

COR Advantage is based on 36 items that are proven by research to best prepare children for school success.


In addition to thoroughly covering eight major areas of growth and development, COR also offers two items specifically designed to support English language learning. COR’s items are based on current early childhood standards, ensuring that teachers have access to widely held expectations of what children should know and be able to do right at their fingertips.


Respectful of teachers’ time, COR Advantage has the fewest items of any early childhood assessment and does not have additional hidden items or dimensions within each category. COR’s structure allows teachers to assess accurately with as few items as possible –– keeping the instructional day focused on what is most important: children’s own interests and explorations.
