New research reveals that English-speaking children continue to refine their capitalization skills well past the early grades, despite being taught the rules early.
Across two studies, students in Grades 3–6 made more errors than older students and relied more heavily on having “two clues”—such as a proper noun at the start of a sentence—to capitalize correctly.
Older students and adults showed stronger mastery but still made occasional unnecessary capitalizations.
The findings suggest that revisiting capitalization rules and focusing on sentence-level understanding can strengthen writing accuracy through adolescence.
