Here's a general breakdown of how the levels work:
Level 1: student did not demonstrate an understanding of the purpose of the task and/or the required skills.
Level 2: student demonstrated some understanding.
Level 3: student demonstrated a good understanding.
Level 4: student demonstrated all of the required skills.
Pictured below are four samples of level 4 responses to assist parents and students in understanding how their own quiz was scored. I've also made a brief video that I hope assists parents and students. My hope is that parents will review the video with their child to help them see where they went wrong and what they did right.
