Levels of Understanding Poster is based on Marzano's Proficiency Scales.
This poster is an easy way to help your students self-assess and monitor where they are with their understanding and an extremely quick and useful tool for teacher's to use as an informal assessment.
I created an enlarged poster of this document in my 8th-grade classroom. Upon completion of a lesson on a new concept, I would have students refer to the poster and hold up their fingers indicating where they felt their understanding was at that time. When I wanted a more in-depth and honest explanation of their understanding, I would have them use this poster as a reference and have them write in their Reader's/Writer's Notebook with their level and an explanation.
