Massachusetts's state writing assessment, rubric by rubric
MCAS (Massachusetts Comprehensive Assessment System) is the state's annual summative assessment program. The writing portion appears within the ELA assessment as a series of constructed-response items. Grades 3 and 4 include both Short Response items and Essay items. Grades 5 through 8 and Grade 10 include longer Essay responses.
MCAS Essay rubrics use a two-trait analytic structure. Idea Development covers quality and development of the central idea or thesis, selection and explanation of evidence and/or details, organization, expression of ideas, and awareness of purpose or task and mode. Standard English Conventions is a separate analytic trait covering sentence structure and grammar, usage, and mechanics.
The Idea Development trait uses a 1 to 4 scale at Grades 3-5 and a 1 to 5 scale at Grades 6-8 and Grade 10. Standard English Conventions uses a 0 to 3 scale at every grade band. For narrative writing (Standard 3), the quality and development of narrative elements (plot, character, setting, dialogue, action, description) is assessed in place of a central idea.
The four MCAS writing rubrics
Each MCAS Essay rubric scores writing on two analytic traits, Idea Development (scored 1 to 5 at higher grades, 1 to 4 at Grades 3-5) and Standard English Conventions (scored 0 to 3). The Short Response rubric is a single-trait 0-3 holistic rubric used for shorter reading-based prompts at Grades 3 and 4.
Single-trait holistic rubric for shorter reading-based written responses at Grades 3 and 4. Students demonstrate understanding of the reading material with important and specific evidence/details for support. Scored 0 to 3.
Two-trait analytic rubric for essay writing at Grades 3 to 5. Idea Development is scored 1 to 4 across central idea, evidence selection, organization, expression of ideas, and awareness of purpose. Standard English Conventions is scored 0 to 3.
Two-trait analytic rubric for essay writing at Grades 6 to 8. Idea Development is scored 1 to 5 across central idea, evidence selection, organization, expression of ideas, and awareness of task and mode. Standard English Conventions is scored 0 to 3.
Two-trait analytic rubric for essay writing at Grade 10. Idea Development is scored 1 to 5 across central idea/thesis, evidence selection, organization, expression of ideas, and awareness of task and mode. Standard English Conventions is scored 0 to 3.
How MCAS scores writing
MCAS Essay rubrics score responses on two analytic traits. Idea Development (1 to 4 at Grades 3-5, or 1 to 5 at Grades 6-8 and Grade 10) is a single overall score derived from five sub-criteria. Standard English Conventions (0 to 3) is a tighter trait covering sentence structure and grammar, usage, and mechanics. The Short Response rubric at Grades 3-4 is a single-trait 0-3 holistic rubric.
Scored 1 to 4 at Grades 3-5 and 1 to 5 at Grades 6-8 and Grade 10. Five sub-criteria are embedded in each score point, quality and development of central idea (or central idea/thesis at Grade 10), selection and explanation of evidence and/or details, organization, expression of ideas, and awareness of purpose (Grades 3-5) or task and mode (Grades 6-8, Grade 10). For narrative writing, narrative elements replace the central-idea criterion.
Scored 0 to 3. Two sub-criteria, sentence structure and grammar, usage, and mechanics. Both are evaluated relative to the length and complexity of the essay. A response with sentences formed incorrectly and no control of grammar, usage, and mechanics, or with insufficient length, earns 0.
Scored 0 to 3 holistically. Used for shorter reading-based prompts that ask students to demonstrate understanding of a text with specific evidence and details. A 3 demonstrates full understanding with important and specific evidence; a 0 demonstrates no understanding with insufficient evidence. Not used at higher grades.
