01 About ISASP

Iowa's state writing assessment, rubric by rubric

ISASP (Iowa Statewide Assessment of Student Progress) is Iowa's annual summative assessment for grades 3 through 11. The writing portion appears within the ELA assessment as a constructed response, where students produce one written response per test in the genre assigned for their grade and form.

ISASP uses the same four-trait analytic rubric structure across every genre and grade band: Prompt Task, Development (of Opinion, Argument, Narrative, or Explanation), Organization, and Language Use. Each trait is scored 1 to 5, for a maximum of 20 points per rubric. The trait names and structure stay constant; the descriptor language at each score point evolves with grade and genre.

Grade 3 uses opinion and narrative only. Informative/explanatory writing enters at Grade 4. Argument replaces opinion starting in Grade 6, and opposing viewpoints become an expectation at Grade 7. High school rubrics at Grades 9 through 11 use the same four traits and add expectations around objective tone, audience anticipation, and logical sequencing.

03 Scoring

How ISASP scores writing

Every ISASP writing rubric scores responses on four analytic traits, each on a 1 to 5 scale. The four traits are the same across every genre and grade, only the descriptor expectations change. A response that earns 5s across all four traits earns 20 points; a typical proficient response lands around a 3 or 4 on each trait.

01
Prompt Task

Scored 1 to 5. Measures how clearly the response addresses the prompt and uses evidence or details from provided texts. At higher score points, the response takes a clear position, uses ample relevant evidence, and (for argument at Grades 7 plus) acknowledges opposing viewpoints.

02
Development (of Opinion, Argument, Narrative, or Explanation)

Scored 1 to 5. Measures the quality and depth of supporting ideas, examples, reasons, and details. At higher score points, the response provides several thoughtful supporting ideas with complete explanation and effective elaboration.

03
Organization

Scored 1 to 5. Measures introduction, conclusion, paragraphing, and use of transitions or temporal words to connect ideas. At higher score points, the response has a well-developed introduction, a logical conclusion, and varied transition words used effectively throughout.

04
Language Use

Scored 1 to 5. Measures word choice, sentence variety, and (at higher grades) audience-appropriate style and tone. At higher score points, the response uses precise and varied word choice with well-controlled sentences of varied length and complexity.

04 FAQ

Common questions about Iowa ISASP writing

What is the ISASP writing rubric?
It is the official Iowa Department of Education rubric for scoring constructed-response writing on the Iowa Statewide Assessment of Student Progress (ISASP) for grades 3 through 11. ISASP uses four-trait analytic rubrics, Prompt Task, Development, Organization, and Language Use, each scored 1 to 5 for a maximum of 20 points per rubric. Separate rubrics exist for opinion, argument, informative/explanatory, and narrative writing.
How many points is each ISASP writing rubric worth?
20 points total per rubric. Each of the four traits (Prompt Task, Development, Organization, Language Use) is scored 1 to 5 independently, then summed. The 1 to 5 scale is consistent across every grade and every genre on ISASP.
What genres does ISASP assess at each grade?
Grade 3 covers opinion and narrative. Grades 4 and 5 add informative/explanatory, for three genres total at those grades. Starting in Grade 6, opinion is replaced by argument, and Grades 6 through 11 are assessed on argument, informative/explanatory, and narrative.
When does ISASP expect opposing viewpoints in argument writing?
Starting in Grade 7. The Grade 6 argument rubric does not require students to acknowledge alternate or opposing viewpoints, but Grades 7, 8, and 9 explicitly add "Acknowledges alternate or opposing viewpoint(s)" to the top score points on the Prompt Task trait. Grades 9 through 11 strengthen this further, expecting students to address both strengths and limitations of their own viewpoint.
Is this rubric the official version from the Iowa Department of Education?
