NNAT® Level C vs Level D: what changes?

Pearson’s NNAT®3 materials list Level C for 2nd grade and Level D for 3rd and 4th grade. If your district screens all 2nd graders and then offers another opportunity later, the later version may use Level D. Chino Valley Unified families, for example, have heard that retakes are typically offered in 4th grade using NNAT Level D.

The structure is similar

Both Level C and Level D are built around nonverbal reasoning. Children work with shapes, colors, patterns, matrices, analogies, and spatial relationships rather than reading passages or vocabulary questions. Both levels use the same overall NNAT3 administration pattern: 48 multiple-choice questions in about 30 minutes.

What gets harder on Level D

The hard part is not a brand-new subject. It is the density of the visual reasoning. Level D questions can ask a child to track more features at once, compare more similar answer choices, and hold a mental transformation steady for longer before choosing an answer.

In Pattern Completion, distractors may match color while breaking one edge of the design. In Reasoning by Analogy, the rule may combine orientation, position, and fill. In Serial Reasoning, the row and column rules may both matter. In Spatial Visualization, a child may need to fold, rotate, or combine pieces mentally before checking the choices.

Why Level C preparation still helps later

A child who understands the four question formats is not starting from zero when the level increases. The same habits carry over: check every edge, name the transformation, test the row and column, and build the folded or combined image before looking at answer choices.

That is why good Level C practice should not be built around memorizing answers. It should teach a child how to read the visual rule. Once that skill is in place, harder Level D questions become more approachable because the child knows what kind of thinking the test is asking for.

What to ask your district

1. Which NNAT level will my child take this year?
2. If my child does not qualify this year, when is the next retake opportunity?
3. Does the later retake use Level D?
4. When are results expected?
5. If my child qualifies, what additional educational opportunities are offered in the current grade level and beyond?

How to practice without overdoing it

For 2nd grade students, start with short, calm sessions that introduce the format. Five or ten focused questions with explanations can be more useful than a long worksheet marathon. Once the child understands the formats, mix in timed practice so pacing becomes familiar.

For older students preparing for Level D, the goal shifts from “what is this question asking?” to “can I hold the rule precisely while choosing among close distractors?” That is where harder practice sets, answer explanations, and full-length timed tests help most.
