Be respectful, and ready to communicate. This will ensure that the conversation is productive, and that no one feels defensive. Teachers and parents have differing areas of expertise, and it is in the best interests of your child for you to combine your expertise to offer the most appropriate help.
Make notes about your concerns. This could include jotting down observations that highlight your concerns. Take into account other circumstances -- a hungry, tired child is less likely to want to read, for example, then a happy one, and may put forth less effort.
Share your observations with your child's teacher. Have you noticed any specific areas that your child seems to struggle with? For example, does he struggle with comprehending the story, or with remembering what has happened? Are there external factors which could be impacting your child's ability to read, such as attention problems? Discuss these, and ask if the same issues occur at school.
Discuss the school's current teaching program. There are a wide range of educational reading programs, one or two of which are usually used by each school. This could be a range of storybooks, for example. Are there changes that could be made to the program to make it more effective for your own child? Some children may benefit from individual reading sessions, for example, or from having more time to read each book.
Share other ways that could help your child develop his reading further. This could be by reading about things that interests him, whether this is a favorite animal, country or activity, or books by a certain author. Magazines and websites can be used alongside books to encourage children to read about their passions.
Talk about how the school can help to support your child. If your child is struggling to read, he may feel frustrated and upset, and may have been put off trying to read. A joint effort between school and home should be made to reassure and encourage.
Make a follow up plan. Include details of what you will do next, details of what the teacher will do next and when you will meet again to discuss the matter. For example, it may be advisable to take your child to have his eyes tested, to see if his vision is adequate. The school may produce an education plan, to show what next steps should be taken, and arrange individual reading sessions. Arrange a scheduled phone call or meeting to discuss progress.
