Deep Dive: How Long Should Students Read Daily to Learn New Vocabulary?

How much should children be reading each day? It is an incredibly important question and one that was answered in a recent paper! This month we’re covering How Much Should I Read? An Analysis of Word Learning Opportunities in Children’s Novels 

The first question we need to answer, though, is how much should read for what purpose? In other words, what is the outcome or goal that the researchers were investigating and in this paper, they were specifically looking at vocabulary growth (new words learned).

Background

Researchers analyzed 45 children’s novels from Project Gutenberg, identified unfamiliar words for different grade levels using vocabulary databases, and used simulation modeling to estimate how many words students could learn based on repetition patterns and established incidental learning rates from the literature.

Why 2,000 words?

The 2,000 word annual target isn’t arbitrary—it’s what research shows students need to learn each year to stay on track for college readiness, with studies indicating that college-ready students know approximately 42,000 words by age 20.

The tl;dr

Sixth grade children should be reading approximately 17 minutes per day during school days (or 8.5 minutes daily year-round) to learn 2,000 new words annually through incidental vocabulary acquisition.

Practical implications

For Educators:

  • Monitor comprehension while students read independently—if they’re struggling with more than 5% of words, the book may be too challenging
  • Focus on strategies that increase incidental word learning rate (using context clues, morphological analysis)
  • Emphasize sustained reading of full-length books rather than just short passages

For Parents:

  • 17 minutes of daily reading during the school year is achievable and impactful
  • Choose books at the right challenge level—not too easy, not too hard
  • Encourage finishing whole books rather than jumping between shorter texts

Some limitations of the study

  • Results are based on public domain books, which may not represent current children’s literature
  • The model focuses solely on vocabulary growth—reading has many other benefits
  • Individual differences mean some students may need more or less reading time

The bottom line

Just 17 minutes of daily reading during school days can put students on a path toward college-level vocabulary—making consistent, sustained reading one of the most efficient investments in academic success.
