Can I make one part of a rubric count more than the others?
Yes. Give that criterion a weight, so its points count two or three times in the total. Tell students which parts are weighted before they start, so they spend their effort where the grade is.

Weighting is useful when one part of the work matters more than the rest. In a science project, getting the ideas right should count for more than how neat the poster is. Without weights, a tidy poster with a wrong conclusion can score as well as a messy one with a right one.
Keep weights few. If every row is weighted differently, students cannot tell what matters, and the arithmetic gets hard to check. One or two weighted rows on a rubric of four to six is usually enough.
In the rubric maker
- Each criterion has a "counts" setting of ×1, ×2 or ×3.
- A weighted row prints "counts ×2" (or ×3) under its name, so students see it on the paper.
- The score column shows each row's most possible points with the weight included, and the total at the bottom adds them up.
- Some premade rubrics for grades 3–8 already weight their most important row. The K–2 versions never do, since they print without points by default.
