The CPOM comprises 16 items to be administered during morning instruction in Kindergarten
through sixth grade classrooms. Alternatively, an abbreviated 10‐item version can be
administered during any other structured classroom instructional period. Observations typically
last 60 minutes and can be scored live in the classroom or using videos of classroom instruction.
Coding materials consist of the coding protocol and a two‐page scoring sheet. Full Measure
