Rethinking Homework: What Actually Works and What to Stop Assigning

The homework debate has been running for decades, and the research findings are consistent enough to guide practice — but they're widely ignored because they conflict with tradition and parental expectations. Teachers assign homework because they always have, because it signals rigor, and because there's work that genuinely doesn't fit in the school day. Students do it (or don't) because it counts toward their grade. Parents expect it because they did homework and therefore believe it matters.

The research doesn't support most of these rationales, and it points clearly toward what does work. This post is about aligning your homework practice with the evidence.

What the Research Actually Says

Elementary school: no consistent relationship between homework and academic achievement. The evidence for homework improving learning in elementary school is weak to nonexistent. The primary effect of homework at this level appears to be teaching students that school is stressful and that learning doesn't stop when you leave the building — and not in a positive way.

Middle school: modest positive relationship between homework and achievement, but highly variable by type of homework. Practice of recently taught skills in modest quantities (ten to thirty minutes) shows some benefit; large projects and long written assignments show less consistent benefit. The relationship is weaker than commonly assumed.

High school: stronger positive relationship, but with diminishing returns above about one to two hours per night across all subjects combined. Beyond that threshold, homework is associated with stress, sleep deprivation, and reduced well-being without additional academic benefit.

The ten-minutes-per-grade rule (ten minutes per night in first grade, twenty in second, up to two hours by high school) captures these findings roughly, though the research support is for "modest quantities" rather than this specific formula.

What Homework Is Worth Assigning

Reading practice: twenty minutes of independent reading at an appropriate level is the homework assignment with the clearest positive effect on reading achievement. It requires no grading, minimal accountability, and compounds dramatically over a school year.

Fluency practice: brief, repeated practice of a skill that needs to become automatic — multiplication facts, sight words, a foreign language vocabulary set. This should be genuinely brief (ten to fifteen minutes) and targeted at skills that genuinely need automaticity.

Preparation for class: watching a short video, reading a brief text, or completing a brief reflection before class discussion. This is the "flipped classroom" model applied to specific lessons where outside preparation genuinely frees class time for higher-level work.

Project work that can't fit in class: extended projects that require time, research, or materials that can't be provided at school. This is legitimate homework, but it requires attention to equity — not all students have the time, space, materials, or support at home to complete project work, and homework that assumes these resources disadvantages students who don't have them.

What to Stop Assigning

Worksheets on new content: students who don't understand the content can't do the worksheet correctly; students who do understand it already are practicing what they don't need to practice. New content is for class time, where you can monitor, respond, and reteach. Sending new content home to be practiced without feedback is an instruction gamble.

Large projects sent home as "homework": projects that require substantial time, materials, or adult support become equity problems. The student with a quiet bedroom, an involved parent, and a laptop produces a different product than the student sharing space with four siblings, working a part-time job, and doing homework on their phone.

Rote copying: copying vocabulary definitions, copying notes from the textbook, writing down facts. This produces the appearance of studying and no actual learning.

Any homework where cheating or copying is trivially easy: if the internet can do the homework, students will let it. This is not a character failure — it's a design failure. Homework that can be done by a quick search needs to be redesigned or eliminated.

The Grading Problem

Homework grades distort the gradebook. Students who have less support at home complete less homework; grading homework on completion or correctness converts home support into academic grades. If your homework grades correlate strongly with socioeconomic status — and they typically do — they're measuring something other than what you intend to measure.

The alternative: don't grade homework for quality. Grade it for completion if you want accountability, or don't grade it at all if the accountability can be maintained through other means (brief class discussion of homework questions, retrieval practice that naturally reveals whether the reading was done). Let the summative assessments — where conditions are equal — carry the grade.

This requires a difficult conversation with parents who believe that grades on homework are appropriate and necessary. That conversation is worth having.

Communicating Your Homework Policy

Whatever policy you adopt, communicate it clearly at the beginning of the year. Parents' expectations for homework are shaped by their own educational experiences and their assumptions about rigor. A teacher who explicitly explains their homework philosophy — what they assign, why, and what research supports — preempts most homework-related complaints.

The most common parental concern: "My child doesn't have enough homework." This usually means "I'm not seeing evidence that rigor is happening." Addressing the underlying concern (rigor, challenge, academic progress) is more productive than increasing homework to address the symptom. Sharing assessment data, noting specific challenging work students are doing, and inviting parents to review their child's class work often satisfies the concern more effectively than a longer homework list.
