What is one constraint in assigning homework which can be done only with parents?

One constraint in assigning homework which can be done only with parents is ensuring that the homework is appropriate for the student's age and developmental level. Parents can help teachers understand their child's strengths and weaknesses, and can provide support and guidance as needed. Additionally, parents can help ensure that the homework is completed in a timely and effective manner, and can provide a quiet and distraction-free environment in which the student can work.
