Rubric descriptors children understand: "I can" wording, one verb a cell, three grade bands

Grades K–87 chapters, about 8 minutesUpdated October 2026

A rubric only helps a student who can read it and find their own work in it. Write each row's goal as an "I can" sentence in the student's voice, put one action in each cell, and make the levels differ by one thing a child can see on the page. Write the middle level first and build the others from it. This guide shows the habits, then walks one criterion through three grade bands using real rows from our premade rubrics.

1 Why the wording decides whether a rubric works

Most rubrics are written for the grown-up who scores them. The words make sense to us because we already know what good work looks like. A student reading the same cell has to guess what "demonstrates thorough understanding" means for the paragraph in front of them, and most give up and look at the points instead.

A rubric written for the student does a different job. Before the work starts, it tells them what to aim at. During the work, it gives them something to check against. Afterward, it tells them what to do next time. None of that happens unless the student can read a cell and say, "That's me" or "That's not me yet."

Three habits do most of the work:

  • Say the goal in the student's voice. An "I can" line turns a criterion into something a child can promise.
  • Put one action in each cell. One verb, one thing to look for, so a student can check it in a few seconds.
  • Change one thing between levels. If "meets" and "exceeds" differ in four ways, nobody can tell which one they are in.

The rest of this guide takes each habit in turn, then shows one criterion written for three ages.

2 Start every row with an "I can" line

Before you write any cells, write one sentence for each row that starts with "I can" and says what meeting the goal looks like. This sentence is the target. It is also the single-point version of the row and the line on a student checklist, so you get three uses from one sentence.

Good "I can" lines share a few traits. They name something the student does, not something they are. They use words the student already uses. They describe the work, not the effort or the attitude. And they are short enough to say aloud in one breath.

  • Weak: "I can be a good writer." (Not something you can check.)
  • Weak: "I can demonstrate organizational coherence." (Words the student doesn't use.)
  • Better: "I can give my talk a beginning, a middle and an end."
  • Better: "I can give reasons for what I think."

The two better lines come straight from the 3–5 presentation rubric and the K–2 opinion writing rubric. Every premade rubric on Rubrics for every assignment carries an "I can" line for each row, and the "Print the I can checklist" button prints those lines on their own.

Try this Read the "I can" lines aloud before the work starts and ask students to put a thumb up for each one they think they can already do. The thumbs tell you which row to teach first.

3 One verb a cell

A cell that asks for three things can't be scored honestly. "Uses vivid words, varied sentences and correct punctuation" leaves you stuck when a student does the first two and not the third. The student is stuck too, because they can't tell which part they missed.

Give each cell one main action, the same verb across the row, and change only how well or how much. The verb is what the student does: tell, give, show, label, look, explain, answer. The change across the row is the amount or the quality.

Look at the K–2 "My reasons" row from the opinion writing rubric:

  • Wow! I give two or more reasons, using "because."
  • Yes: I give one reason.
  • Not yet: I do not give a reason yet.

Every cell uses the same verb, give. The only thing that changes is how many reasons. A six-year-old can count their reasons and find their cell without help.

If a row truly needs two actions, it is usually two rows. Split "capitals and periods and spaces" into separate rows for young writers, or keep them together only when you will teach and check them as one habit, as the K–2 opinion rubric's "Capitals and periods" row does.

4 Write the middle first, then change one thing

The level that matters most is the one that says "you did what was asked." In a K–2 rubric that is Yes; in a 3–5 or 6–8 rubric it is Meets. Write that cell first, and make it match exactly what you taught. Then write the other levels as changes to that sentence.

  1. Write the middle cell as a plain description of the work you expect.
  2. Write the level above by adding one thing a student can see: a second reason, a source named, an ending that loops back.
  3. Write the level below by taking one thing away or making it partial: the reason is there but not explained, the order is there but jumps.
  4. Write the bottom level as "not yet" for that same thing, never as a judgment of the student.

This keeps the levels honest. A student who reads the row sees one ladder with one rung changing, not four different paragraphs. It also stops the top level from turning into "everything in the middle cell, plus be amazing", which nobody can aim at.

Avoid words that only rank: excellent, good, fair, poor, some, many. Each of them needs the reader to know the other levels to make sense. Words that describe the work, such as "one reason" or "two or more reasons", make sense on their own.

5 One criterion written for three ages

The same skill grows up across the grades. Here is the "reasons" row from our opinion writing rubric in all three bands, word for word, so you can see what changes and what stays.

K–2: My reasons (three levels, no points)

  • I can give reasons for what I think.
  • Wow! I give two or more reasons, using "because." Yes: I give one reason. Not yet: I do not give a reason yet.

3–5: Reasons and facts (four levels, counts twice)

  • I can give reasons and back them up with facts and details.
  • Exceeds: Three or more strong reasons, each backed by facts, examples or details. Meets: Two or three reasons with some facts or details. Approaching: Reasons are few or not backed up. Beginning: Reasons are missing or do not support the opinion.

6–8: Reasons and evidence (four levels, counts twice)

  • I can support my claim with logical reasons and credible evidence.
  • Exceeds: Logical reasons, each supported by relevant, credible, cited evidence and explained. Meets: Clear reasons supported by relevant evidence with some explanation. Approaching: Evidence is weak, uncited or not explained. Beginning: Reasons rest on opinion with little or no evidence.

Notice three things. The K–2 cells are in the first person, so a child reading them is reading about themselves. The 3–5 cells add one new demand, backing reasons up, and keep counting as the main ladder. The 6–8 cells change what counts as backing: credible, cited and explained. The criterion is the same skill each time, asked of an older writer.

6 Test it on a student before you print thirty

The quickest check for any rubric is to hand it to one student with a piece of their own work and ask, "Which box are you in for this row?" If they can point and explain why, the row works. If they hesitate, guess, or point at the points, the wording needs another pass.

  • Can a student read every word in the row, or follow along while you read it?
  • Does each cell name one thing they can see on their own page?
  • Do neighboring levels differ by one thing, and can the student say what it is?
  • Is the "I can" line something the student could promise to do tomorrow?
  • Is there any word, such as "adequate" or "sophisticated", that only makes sense to an adult?

Length is a warning sign too. The free rubric maker shrinks the type to fit each printed cell, and it tells you when a cell is long enough to print very small. Treat that note as a wording note, not a layout problem. Cut the cell to one action and it will fit.

Watch for Ask a student to read their row aloud to a partner and say what they would change to move up one level. If they can say it, your descriptor is doing its job.

7 Words to swap for ones a child can use

A handful of rubric words turn up everywhere and mean very little to a student. Here are plain swaps that keep the meaning and make the cell something a child can check.

  • "Demonstrates understanding" becomes "tells what it means in my own words" or "answers a question about it."
  • "Organized" becomes "has a beginning, a middle and an end" or "puts my steps in order."
  • "Uses details" becomes "adds a fact, an example or something I saw."
  • "Appropriate volume" becomes "everyone hears every word."
  • "Maintains eye contact" becomes "I look at my friends while I talk."
  • "Few errors" becomes "a few mistakes that don't confuse the reader."
  • "Creative" becomes "shows my own idea, not a copy of the example."

Keep the grown-up words where older students need to learn them. A 6–8 rubric can say "claim", "evidence" and "counterclaim" because those are the words of the assignment, and part of the lesson is learning what they mean. Teach the word first, then let the rubric use it.

When you are done, open the row in the rubric maker and switch the kind to Single-point. If the "I can" line still makes sense with no levels around it, the row is ready.

Questions teachers ask

What is a rubric descriptor?
A descriptor is the text in one cell of a rubric: what work at that level looks like for that criterion. Good descriptors name something a student can see in their own work, so they can find their level without asking.
Should rubric descriptors be written in the first person?
For kindergarten to 2nd grade, yes: "I give one reason" reads as a sentence about the child. For older students, the "I can" line can stay first person while the cells describe the work in plain third person, as our 3–5 and 6–8 rubrics do.
How many words should a rubric cell have?
As few as it takes to name one action and how well it was done. If the cell needs "and" twice, it probably holds two criteria. The rubric maker warns you when a cell is long enough to print in very small type.
Where do "I can" statements go on a rubric?
Beside each criterion, as the target for that row. They also work on their own as a student checklist or as the standard in a single-point rubric, which is why every premade rubric on this site has one per row.
