Maintain your common sense. Reading problems are comprehensible in the realm of your ordinary experience. They are not strange or fantastic conditions understood only by experts. You do not have to be a teacher or a specialist to help a student who is experiencing problems. It is possible that you can help your student yourself, especially with some knowledgeable assistance.
Some students are easier to teach than others.
Some students can be downright difficult to teach. For this or other reasons, you may decide that it is best not to teach your student yourself. Use your common sense in deciding whether, and in what ways, you will teach. Demonstrate to students that they are competent. Students who have had problems in the early stages of learning to read, may have lost confidence in their ability.
