New Mexico's state writing assessment, rubric by rubric
NM-MSSA (New Mexico Measures of Student Success and Achievement) is the state's annual summative ELA assessment for grades 3 through 8. The writing portion uses analytic rubrics that score responses across five traits, three for Production of Writing and two for Use of Conventions.
NM-MSSA splits writing scoring into two rubrics. The Production of Writing rubric scores Development/Content, Organization/Focus, and Language, each on a 4-point scale (1 to 4). The Use of Conventions rubric is shared across all grades 3 through 8 and scores Grammar/Usage and Mechanics, each on a 3-point scale (1 to 3). Maximum total per rubric is 18 points.
Genre-specific descriptor language varies, but the trait structure stays constant. Argumentative writing adds an alternate or opposing claims expectation beginning in grade 7. Narrative writing adds a context and point of view expectation beginning in grade 7. These grade-specific expectations are footnoted in the source rubrics.

How MSSA scores writing
Every NM-MSSA writing rubric scores responses on five analytic traits across two rubrics. The Production of Writing rubric covers Development/Content (1 to 4), Organization/Focus (1 to 4), and Language (1 to 4). The Use of Conventions rubric covers Grammar/Usage (1 to 3) and Mechanics (1 to 3). The Use of Conventions rubric is shared across all assessed grades 3 through 8.
Three traits scored 1 to 4 each. Development/Content captures how thoroughly the writing addresses the task and how substantially the topic, opinion, claim, or narrative is developed using relevant sources or descriptive details. Organization/Focus captures the organizational plan, introduction and conclusion, and use of linking words or transitions. Language captures precise word choice, varied vocabulary, and style/tone appropriate to the task.
Two traits scored 1 to 3 each. Grammar/Usage captures command of standard English grammar and usage relative to the length and complexity of the text. Mechanics captures command of standard English conventions including punctuation, capitalization, and spelling. The Use of Conventions rubric is shared across all NM-MSSA grades 3 through 8.
A few descriptor bullets in the source rubrics carry a footnote noting that they are only assessed at grades 7 and 8. These include alternate or opposing claims on the argumentative rubric and context and point of view on the narrative rubric. The 5-trait structure and 4/4/4/3/3-point scales stay constant across grade bands.
