Parents fight about it. Teachers assign it. Students hate it. But does homework actually work? We checked 30 years of meta-analyses.
After looking at the evidence, a few things stood out to me.
The Evidence Is Surprisingly Clear
Cooper et al. (2006) analyzed 60+ studies spanning 3 decades. The findings:

- Elementary school (K-5): Near-zero correlation between homework and achievement. Reading is the exception.
- Middle school (6-8): Modest positive effect, but only up to 60-90 minutes per night. More than that = diminishing returns.
- High school (9-12): Meaningful positive effect, peaking at about 2 hours per night.
The 10-Minute Rule
The National PTA and NEA endorse the 10-minute rule: 10 minutes per grade level per night. Grade 1 = 10 min. Grade 6 = 60 min. Grade 12 = 120 min. This aligns almost perfectly with the research.
What Type of Homework Matters
- Practice (math problems, reading): Works. Reinforces skills.
- Preparation (pre-reading for tomorrow): Works. Primes learning.
- Projects and busywork: No evidence of benefit. Often counterproductive.
