I have a student in my classroom that has enrolled in public school for the first time this year as a third grader. Previously, he was homeshooled. I noticed quickly that he had a difficult time reading and calling basic site words. After performing a reading assessment on him, I realized he was on a first grade reading level. After bringing his parents in to discuss his progress, I asked their permission to begin the RTI process on their child to start inventions in reading. They were against the idea and said their son could read just fine and I was the first person to ever comment on his reading ability. They did not want him to get any more support because they did not believe he had a problem, even after showing them his responses to the testing information. How can I make them see that he needs help and is struggling in all subject areas because he has difficulty reading?
