In recent years, homework has become a very hot topic. Many parents and educators have raised concerns about homework and questioned how effective it is in enhancing students’ learning. There are also concerns that students may be getting too much homework, which ultimately interferes with quality family time and opportunities for physical activity and play. Research suggests that these concerns may be valid. For example, one study reported that elementary school students, on average, are assigned three times the recommended amount of homework.

So what does the research say? What are the potential risks and benefits of homework, and how much is too much?

Academic benefits

First, research finds that homework is associated with higher scores on academic standardized tests for middle and high school students, but not elementary school students. A recent experimental study in Romania found some benefit for a small amount of writing homework in elementary students but not math homework. Yet, interestingly, this positive impact only occurred when students were given a moderate amount of homework (about 20 minutes on average).

Non-academic benefits

The goal of homework is not simply to improve academic skills. Research finds that homework may have some non-academic benefits, such as building responsibility, time management skills, and task persistence. Homework may also increase parents’ involvement in their children’s schooling. Yet, too much homework may also have some negative impacts on non-academic skills by reducing opportunities for free play, which is essential for the development of language, cognitive, self-regulation and social-emotional skills. Homework may also interfere with physical activity and too much homework is associated with an increased risk for being overweight. As with the research on academic benefits, this research also suggests that homework may be beneficial when it is minimal.

What is the “right” amount of homework?

Research suggests that homework should not exceed 1.5 to 2.5 hours per night for high school students and no more than one hour per night for middle school students. Homework for elementary school students should be minimal and assigned with the aim of building self-regulation and independent work skills. Any more than this and homework may no longer have a positive impact.
