However, this relationship is influenced by such factors as differences in students' grade level. Although statistics concerning the average number of hours spent on homework provide one indication of the role of homework, they do not address the quality of the homework assigned, the degrees to which students actually complete homework, or the effort and care students take in completing it. The corresponding percentages were much lower in all the other countries reported, except in Canada and Scotland at ages 9 and 13 and in Spain at age 9. Whereas the majority of students in all the countries reported having completed no more than 1 hour of homework a day at age 9, by age 13 the majority of students in about half these countries completed at least 2 hours of homework daily. In the United States, however, the majority of students still continued to complete no more than 1 hour of homework a day at age 13.
