If your block has a written response and you do not hand score it, your report is incomplete and your students look worse than they are.

Calibration is not about being strict. It is about scoring the same way your colleagues do.
Explain why 3/8 + 2/8 = 5/8 and not 5/16. Worth 2 points.
2 Explains what the denominator names 4 “The 8 tells how many pieces the whole got cut into. That does not change when you put pieces together.”
1 Correct conclusion, no reasoning 11 “It is 5/8. I know because I did it that way in class.”
0 Added denominators, restated or blank 9 “You add the tops, and you add the bottoms. So it is 5/16.”
Eleven students got the right answer and could not say why. Only the written item shows that. What made the 2 a 2: the student names the unit, says what stays the same, and counts in the unit.

COMMON TRAPS
Scoring the answer
5/8 is correct, but the rubric scores the reasoning.
Reading into the answer
Score only what is on the page.
The last paper you scored
Compare to the anchors instead.
Undefined words
Agree as a team on what “explains” means.
Rubric: The scoring guide. It describes what each score point looks like.
Anchor paper: A real student response that shows one score point. Score against anchors, not against the last paper you read.
Calibration: Scoring the same responses as a team until you agree. The goal is consistency, not strictness.
Annotation: A note explaining why a response earned its score, tied to the rubric’s words.
Traits: The separate parts of writing, each scored on its own. ELA writing has three:
Organization/Purpose (4 to 1): A clear focus, held through the whole piece, with a beginning, an end, and transitions.
Evidence/Elaboration (4 to 1): Details that support the ideas, explained and connected. In narrative writing, this trait is called Development/Elaboration.
Conventions (2 to 0): Grammar, capitalization, punctuation, and spelling. They’re scored only here, never in the other two traits.
Purpose: What the writing is meant to do. Each purpose has its own rubric.
Narrative (grades 3 to 8): Tell a story.
Opinion (grades 3 to 5) and Argumentative (grades 6 to 11): Take a position and support it.
Informational (grades 3 to 5) and Explanatory (grades 6 to 11): Explain a topic using sources.
Performance task: A set of activities built around one scenario. It ends with a full piece of writing and takes one to two class periods.
