The speaker wanders off the topic. Math problems for high stakes testing will often use a holistic rubric. Each criterion needs to be described for each of these performance ratings.
The speaker appears to ignore the listener and the situation. Descriptive ratings may be more informative for students to see how well they are performing, and not necessarily what final numerical grade they are receiving.
Use numbers where appropriate Use consistent leveling throughout; do not make big jumps between each box for one criterion, and then do incremental steps between others.
A holistic rubric scores more quickly than an analytic, and often judges the overall understanding of content or quality of performance.
The speaker says practically nothing. The speaker adapts the content in a specific way to the listener and situation.
The pronunciation and enunciation are clear.
