While the researchers’ focus was on measuring teaching quality at the preschool level, instruments for all grade levels were evaluated. Only COEMET is for the preschool age group, the other 2 instruments are for K-12. However, based on their study, the researchers note that RTOP seems to be more suited for older grades (grades 6 to university level) whereas the Inside the Classroom Observation Protocol seems to be better suited to the younger grades (grades K-5).
“The broad range of applicability for many of these measures is possible because they do not focus on information that is specific to an age range, instead addressing constructs that apply to education of students of all ages,” the researchers report.
